Trans-European conventional rail system

Technical specification for interoperability subsystem Telematic Applications for Freight

1.INTRODUCTION

1.1.Technical scope

This TSI concerns the telematic applications subsystem for freight services shown in the list in point 1(b) of Annex II to Directive 2001/16/EC.

The commercial operation of trains, wagons and intermodal units throughout the trans-European rail network requires efficient interchange of information between the different Infrastructure Managers, Railway Undertakings and other service providers. Performance levels, safety, quality of service and cost depend upon such compatibility and interchange as does, in particular, the interoperability of the trans-European conventional rail system.

The technical specification for interoperability also has an impact on the conditions of use of rail transport by users. In this respect the term users is understood to mean not only infrastructure managers or railway undertakings but also all other service providers such as wagon companies, intermodal operators and even customers.

Last but not least, the benefit of interoperability of the conventional rail system was taken into account to bring about the conditions for greater interoperability between modes of transport, in particular between conventional rail transport and combined rail transport.

The purpose of this TSI is to ensure also that efficient interchange of information is at all times best adapted, with regard to quality and quantity, to changing requirements so that the transport process may remain as economically viable as possible and that freight transport on rail maintains its hold on the market against the intense competition it has to face.

All this means the building or upgrading of the trans-European conventional rail system for conventional rail transport and intermodal transport. The need for such an upgrade of the rail part of the transport system can also be seen by considering the critical points (interfaces between the various partners involved) in freight transport on road compared with the critical points of freight transport on rail for one simplified scenario as shown in Annex A, Index 5, Chapter 1.1.

To manage shipments under the conditions of so many interfaces by means of information exchange on the basis of the Directives 2001/14/EC(1) and 2001/16/EC of the European Parliament and of the Council is the final goal of this TSI.

This short explanation of the scope of the conventional rail TSI telematic applications for freight also shows the difference to the Conventional Rail TSI Operation and Traffic Management. The Operation and Traffic Management TSI covers — especially under safety aspects — the procedures and related equipment enabling a coherent operation of the different structural subsystems including, in particular, train driving, traffic planning and management, which is the principal business of an RU according the definition (see Chapter 2.3: Overview of the subsystem description).

The TSI telematic applications covers the applications for freight services and the management of connections with other modes of transport which means that it concentrates on the transport services of an RU in addition to the pure operation of trains. Safety aspects are only considered as far as the existence of data elements, e.g. wrong or not actual values, may have an impact on the safety operation of a train.

1.2.Geographical scope

The geographical scope of this TSI is the trans-European conventional rail system as described in Annex I to the Directive 2001/16/EC. But this TSI may also be applied to the complete freight transport rail network of the Member States of the EU, with the restriction that the requirements of this TSI are not mandatory for freight transport arriving from or going to a non-EU country.

1.3.Content of this TSI

In accordance with Article 5(3) of Directive 2001/16/EC, this TSI:

Lastly, this TSI also comprises, in Chapter 4 (Characterisation of the subsystem), the operating and maintenance requirements specific to the scope indicated in paragraphs 1.1 (Technical scope) and 1.2 (Geographical scope) above.

2.DEFINITION OF SUBSYSTEM/SCOPE

2.1.Functions within the scope of the TSI

The subsystem Telematic Applications for Freight is defined by Annex II of the Directive 2001/16/EC, Section 2.5(b).

It includes in particular:

applications for freight services, including information systems (real-time monitoring of freight and trains),
marshalling and allocation systems, whereby under allocation systems is understood train composition,
reservation systems, whereby here is understood the train path reservation,
management of connections with other modes of transport and production of electronic accompanying documents.

2.2.Functions outside the scope of the TSI

Payment and invoicing systems for customers are not within the scope of this TSI, nor are such systems for payment and invoicing between various service providers such as railway undertakings or infrastructure managers. The system design behind the data exchange in accordance with Chapter 4.2 (Functional and technical specifications of the subsystem), however, provides the information needed as a basis for payment resulting from the transport services.

Also the long-term planning of the timetables is out with the scope of this telematic applications TSI. Nevertheless at some points there will be reference to the outcome of the long-term planning in so far as there is a relationship to the efficient interchange of information required for the operation of trains.

2.3.Overview of the subsystem description

2.3.1.Involved entities

This TSI takes into account the present service providers and the various possible service providers of the future involved in freight transport as they are for (this list is not exhaustive):

wagons
locomotives
drivers
switching and hump shunting
slot selling
shipment management
train composition
train Operation
train monitoring
train controlling
shipment monitoring
inspections and repair of wagon and/or locomotive
customs clearance
operating intermodal terminals
haulage management.

Some specific service providers are defined explicitly in the Directives 2001/14/EC and 2001/16/EC. Since both directives have to be taken into account, this TSI considers in particular the definition of (see also Annex A, Index 6):

‘“Infrastructure Manager (IM)” means any body or undertaking that is responsible, in particular, for establishing and maintaining railway infrastructure. This may also include the management of infrastructure control and safety systems. The functions of the infrastructure manager on a network or part of a network may be allocated to different bodies or undertakings.’

Based on this definition, this TSI regards an IM as the service provider for the allocation of paths, for controlling/monitoring the trains and for train/path related reporting.

According to Directive 2001/14/EC the body or undertaking to which an IM allocates a path is defined as an applicant.

‘“Applicant” means a licensed railway undertaking and/or an international grouping of railway undertakings, and, in Member States which provide for such a possibility, other persons and/or legal entities with public service or commercial interest in procuring infrastructure capacity, such as public authorities under Regulation (EEC) No 1191/69 and shippers, freight forwarders and combined transport operators, for the operation of railway services on their respective territories.

Whereas a “Railway Undertaking” is defined as any public or private undertaking, licensed according to applicable Community legislation, the principal business of which is to provide services for the transport of goods and/or passengers by rail with a requirement that the undertaking must ensure traction; this also includes undertakings which provide traction only.’

Based on this definition, this TSI regards the RU as the service provider for operating trains.

Regarding the allocation of a train path for running a train, Article 13 of the Directive 2001/14/EC also has to be taken into account:

‘Infrastructure capacity shall be allocated by an infrastructure manager, and once allocated to an applicant may not be transferred by the recipient to another undertaking or service. Any trading in infrastructure capacity shall be prohibited and shall lead to exclusion from the further allocation of capacity. The use of capacity by a railway undertaking when carrying out the business of an applicant who is not a railway undertaking shall not be considered as transfer.’

In relation to the communication scenarios between infrastructure managers and applicants in the execution mode of a transport, only the IM and the RU have to be considered and not all types of applicants, which may be relevant for the planning mode. In the execution mode a defined IM–RU relationship is always given, for which the message exchange and the information storage is specified in this TSI. The definition of an applicant and the resulting path allocation possibilities remain uninfluenced.

As already mentioned various services have to be provided for a freight transport. One for example is the provision of wagons. This service can be related to a fleet manager. If this service for a transport is one of the services offered by the RU, the RU acts also as fleet manager. A fleet manager again can manage his own wagons and/or wagons from another keeper (another service provider for freight wagons). The needs for this kind of service provider are taken into account independent of whether the legal entity of the fleet manager is an RU or not.

This TSI does not create new legal entities and does not force an RU to involve external service providers for services which the RU itself offers but it does name, where necessary, a service by the name of a related service provider. If the service is offered by an RU, the RU acts as the service provider for that service.

When taking into account the needs of a customer, one of the services is to organise and manage the transport line according to the commitment to the customer. This service is provided by the Lead Railway Undertaking (Lead RU or LRU). The LRU is the single point of contact for the customer. If more than one railway undertaking is involved in the transport chain, the LRU is also responsible for the co-ordination with the other railway undertakings.

This service can also be undertaken by a forwarder or by any other entity.

The involvement of an RU as LRU can differ from one type of transport flow to another. In the intermodal business the managing of capacity in block trains and the preparing of waybills is done by an intermodal service integrator, who could then be customer for the LRU.

The main point, however, is that the RUs and the IMs and all other service providers (in the sense as defined above) must work together, either through cooperation and/or open access, as well as through efficient interchange of information, to deliver seamless services to the customer.

2.3.2.Considered processes

This TSI for the railway freight transport industry is limited according to Directive 2001/16/EC to IMs and RUs/LRUs with reference to their direct customers.

In the operation of freight services, the activity of an LRU, regarding a consignment, starts with the receipt of the consignment note from its customer and, for example, for wagon loads with the release time of the wagons. The LRU creates a preliminary trip plan (based on experience and/or contract) for the transport journey. If the LRU intends to have the wagon load in a train under Open Access mode (the LRU operates the train for the complete journey), the preliminary trip plan is per se the final one. If the LRU intends to put the wagon load in a train which involves the cooperation of other RUs, he first has to find out which RUs he should address and at what time an interchange between two successive RUs can occur. The LRU then prepares the preliminary wagon orders individually for each RU as subsets of the full consignment note. The wagon orders are specified in Chapter 4.2.1 (Consignment note data).

The addressed RUs check the availability of the resources for the operation of the wagons and the availability of the train path. The responses from the various RUs enable the LRU to refine the trip plan or to start the interrogation anew — perhaps even with other RUs — until the trip plan finally fits customer requirements.

The RUs/LRUs must in general have, at minimum, the capability of:

DEFINING services in terms of price and transit times, wagon supply (where applicable), wagon/intermodal unit information (location, status and the wagon/intermodal unit related estimated time of arrival ‘ETA’), where shipments can be loaded on empty wagons, containers, etc.,
DELIVERING the service that has been defined in a reliable, seamless manner through the use of common business processes and linked systems. There must be a capability for RUs, IMs and other service providers and stakeholders such as customs to exchange information electronically,
MEASURING the quality of the service delivered compared to what was defined. i.e. billing accuracy against price quoted, actual transit times against commitments, wagon ordered against supplied, ETAs against actual arrival times,
OPERATING in a productive manner in terms of utilisation: train, infrastructure and fleet capacity through the use of business processes, systems and data exchange required to support wagon/intermodal unit and train scheduling.

The RUs/LRUs as an applicant must also provide (through contracts with IMs) the required train path and must operate the train within their journey section. For the train path they may use already booked paths (in planning mode) or they have to request an ad hoc train path from the infrastructure manager(s) (IMs) relevant for the journey section(s) over which the RU operates the train. In Annex A, Index 5, Chapter 1.2 an example is given for the path request scenario.

The path ownership is also import for the communication during the train running between IM and RU. The communication must always be based on train and path number, whereby the IM communicates with the RU, who has booked the train path on his infrastructure (see also Annex A, Index 5, Chapter 1.2).

If an RU provides the complete journey A–F (Open Access by RU, no other RUs are involved), then each IM involved communicates directly with this RU only. This ‘open access’ by the RU can be realised by booking the train path via ‘One Stop Shop’ or in sections with each IM directly. The TSI takes account both cases as it is shown in Chapter 4.2.2.1: Path request, Preliminary remarks .

The dialogue process between RUs and IMs for establishing a train path for a freight train is defined in Chapter 4.2.2 (Path request). This function refers to Article 23(1) of the Directive 2001/14/EC. The dialogue process excludes obtaining the licence for an RU providing services in accordance with Directive 2001/13/EC of the European Parliament and of the Council(3), the certification according to Directive 2001/14/EC and access rights according to Council Directive 91/440/EEC(4).

In Chapter 4.2.3 (Train preparation) is defined the information exchange relating to the train composition and the train departure procedure. The data exchange during the running of a train in the case of normal operation is given in Chapter 4.2.4 (Train running forecast) and for exceptions the messages are defined in Chapter 4.2.5 (Service disruption information). Tracing information about train location is defined in Chapter 4.2.6 (Train location). All these messages are exchanged between RU and IM and based on trains.

For a customer the most important information is always the estimated time of arrival (ETA) for his shipment. From the information exchange between LRU and IM (in case of Open Access) an ETA can be calculated. In the case of cooperation mode with various RUs, the ETA and also the estimated times of interchange (ETIs) can be determined from the message exchange between RUs and IMs and provided to the LRU by the RUs, (Chapter 4.2.7 Shipment ETI/ETA).

Also determined from the information exchange between IM and RU, the LRU knows, for example:

when the wagons departed from or arrived at a yard or at defined locations (Chapter 4.2.8 Wagon movement), or
when the responsibility for the wagons was transferred from one RU to the next RU in the transport chain (Chapter 4.2.9 Interchange reporting).

Determined not only from the data exchange between IM and RU, but also from the data exchange between RUs and LRU, various statistics may be evaluated:

for — in the medium term — planning the production process in greater detail, and
for — in the long term — carrying out strategic planning exercises and capacity studies (e.g. network analyses, definition of siding and marshalling yards, rolling stock planning), but above all
for improving the quality of the transport service and productivity (Chapter 4.2.10 Data exchange for quality improvement).

The handling of empty wagons takes on particular relevance when considering interoperable wagons. In principle there is no difference in the handling of loaded or empty wagons. The transport of empty wagons is also based on wagon orders, whereby the fleet manager for these empty wagons must be considered as a customer.

2.3.3.General remarks

An information system is only as good as the reliability of the data within it. Therefore the data that plays a decisive role in the forwarding of a consignment, a wagon or a container must be accurate and captured economically — which means that the data should be entered into the system only once.

Based on this, the applications and messages of this TSI avoid the multiple manual data input by access to already stored data, e.g. the rolling stock reference data. The requirements regarding the rolling stock reference data are defined in Chapter 4.2.11 (The main reference data). The specified Rolling Stock Reference Databases must allow easy access to the technical data. The contents of the databases must be accessible, based on structured access rights depending on privilege, to all IMs, RUs and fleet managers, in particular for purposes of fleet management and rolling stock maintenance. They must contain all transport critical technical data such as:

identification of rolling stock,
technical/design data,
assessment of compatibility with the infrastructure,
assessment of relevant loading characteristics,
brake relevant characteristics,
maintenance data,
environmental characteristics.

In the intermodal transport business at various points (called gateways) a wagon is not only connected to another train, but also the intermodal unit may be moved from one wagon to another. As a consequence it is not sufficient to work with only a trip plan for wagons and therefore a trip plan for the intermodal units must also be drawn up.

In Chapter 4.2.12 (Various reference files) some reference files and various databases are listed, among them, the Wagon and Intermodal Unit Operational Database. This database contains the operational status data of the rolling stock, the weight and dangerous goods information, information related to intermodal units and the location information. In Chapter 4.2.13 (Electronic transmission of documents) the requirements for the electronic transmission of documents are given.

The TSI for telematic applications subsystem for freight services defines the required information, which has to be exchanged between the different partners involved in a transport chain, and permits a standard mandatory data exchange process to be installed. It shows also the architecture strategy for such a communication platform. This is outlined in Chapter 4.2.14 (Electronic transmission of documents) taken into account:

the interface to the subsystem Operation and Traffic Management of the trans-European conventional rail system referred to in Article 5(3) of Directive 2001/16/EC,
the requirements for the content of the Network Statement, which are set out in Directive 2001/14/EC, Article 3 and Annex I,
the information available on the freight wagon rolling stock and the requirements regarding maintenance from the rolling stock TSI.

There is no direct data transmission from the subsystem Telematic Applications for Freight Services into the train, to the driver or to parts of the Control Command and Signalling subsystem and the physical transmission network is a completely different one from the network used by the Command Control and Signalling subsystem. The ERTMS/ETSC system is using GSM-R. In this open network the ETCS specifications clarify that safety is achieved with the appropriate management of open networks hazards in the EURORADIO protocol.

The interfaces to the structural subsystems Rolling Stock and Control Command are only given via the Rolling Stock Reference Databases (Chapter 4.2.11.3: The Rolling Stock Reference Databases), which are under the control of the keepers. The interfaces to the subsystems Infrastructure, Control Command and Energy are given with the path definition (Chapter 4.2.2.3: Path Details message) from the IM, where infrastructure related values for the train are specified, and with the information provided by the IMs regarding restrictions in the infrastructure (Chapter 4.2.11.2: The Infrastructure Restriction Notice Databases).

4.CHARACTERISATION OF THE SUBSYSTEM

4.1.Introduction

The trans-European conventional rail system, to which Directive 2001/16/EC applies and of which the telematic applications subsystem is a part, is an integrated system whose consistency must be verified. This consistency must be checked in particular with regard to the specifications of the subsystem, its interfaces vis-à-vis the system in which it is integrated, as well as the operating and maintenance rules.

Taking into account all the applicable essential requirements, the telematic application subsystem for freight is characterised by:

4.2.Functional and technical specifications of the subsystem

In light of the essential requirements in Chapter 3 (Essential requirements), the functional and technical specifications of the subsystem are as follows:

consignment note data,
path request,
train preparation,
train running forecast,
service disruption information,
train location,
wagon/intermodal unit ETI/ETA,
wagon movement,
interchange reporting,
data exchange for quality improvement,
the main reference data,
various reference files and databases,
electronic transmission of documents,
networking and communication.

The detailed specifications are outlined below. Further details and the formats of the messages are defined in Annex A, Index 1.

General remarks on the message structure

The messages are structured into two data sets:

control data: explanation see below,
information data: the application information.

The control data show the following elements:

status: the status of a message can be:
- ‘New message’, if this is a new message,
- ‘Alteration’, if this is a modification of a previous send message,
- ‘Deletion’, if the previous sent message should be deleted,
message reference with:
- Message type: e.g. ‘path request’ or ‘enquiry about train running’,
- Data and time: actual date and time when the message was sent,
- Message number: number generated by the sender of the message,
related reference, only if the message is the answer to a previous received message (identical to the ‘message reference’ of the received message) with:
- Related type: type of the received message,
- Related date and time: date and time of the received message,
- Related number: number of the received message,
sender of the message,
recipient of the message.

In the following chapters mainly the status ‘New message’ is considered. In Chapter 4.2.2 Path request is also referred to the status ‘deletion’ regarding the Path Request message.

4.2.1.Consignment note data

4.2.1.1.Customer consignment note

The consignment note has to be sent by the customer to the Lead RU. It must show all the information needed to carry a consignment from the consignor to the consignee. The LRU must supplement this data with additional information. These data, including the additional ones, are (for the description of the data see Annex A, Index 3) listed in the table in Annex A, Index 3 with the indication in row ‘Data in consignment note’, whether they are mandatory or optional and whether they must be delivered by the consignor or supplemented by the LRU.

In the case of Open Access the Lead RU contracting with the customer has all the information after the supplement of the data available. No message exchange is needed with other RUs. These data are also the basis for a path request on short notice, if this is required for the execution of the consignment note.

The following messages are for the case of non Open Access. The content of these messages may also be the basis for the path requests on short notice, if required for the execution of the consignment note.

4.2.1.2.Wagon orders

The wagon order is primarily a subset of the consignment note information. It must be forwarded to the RUs involved in the transport chain, since it could become an input for an ad hoc path request (Chapter 4.2.2: Path request). The content of the wagon order must show the relevant information which is needed for an RU to effect transportation during its responsibility until handover to next RU. Therefore the content is dependent on the role to be performed by the railway undertaking: Origin-, Transit- or Delivery RU (ORU, TRU, DRU):

wagon order for the Origin Railway Undertaking (ORU),
wagon order for the Transit Railway Undertaking (TRU),
wagon order for the Delivery Railway Undertaking (DRU).

The data of the wagon orders according the various roles of an RU are listed in detail in Annex A, Index 3, marked as to whether they are mandatory or optional. The detailed formats of these messages are defined in Annex A, Index 1.

The main contents of these wagon orders are:

consignor and consignee information,
routing information,
consignment identification,
wagon information,
place and time information.

Selected data of the consignment note data must also be accessible for all partners (e.g. IM, keeper, etc.) in the transport chain including customers. These are especially per wagon:

load weight (gross weight of the load),
CN/HS number,
dangerous goods information,
transportation unit.

4.2.2.Path request

4.2.2.1.Preliminary remarks

Long-term planning

The train path defines the requested, accepted and actual data to be stored concerning the path of a train and the characteristics of the train for each segment of that path. The following description presents the information which must be available to the infrastructure manager. For a more detailed description: see Annex A, Index 4.

This information must be updated whenever a change occurs.

The main path data must be:

identification of the train path (path number). A path could be either planned usage of capacity along a route section, or the actual routing of a train along a specified line within a route. The exact nature depends upon the processes in use within an IM,
path departure point, which means the place from where the path will start together with the date and time of the departure of a train on that path,
destination of the train path, which means the place where the path will end together with date and time at which a train is due to arrive at that destination,
description of the journey section, which defines the data provided by the IM for each accepted journey section — from the start to the first intermediate stop, further intermediate stops and from the final intermediate stop to the end of the accepted journey. This description may comprise:
- intermediate stops or other designated points along the proposed path with date and time for the arrival, departure or passage at these intermediate points as well with an Activity Code, which defines an activity to be undertaken at that intermediate point en route,
- identification of the IM responsible for the traffic management for the current journey section and identification of the IM responsible for the traffic management for the next journey section,
- description of the equipment (command and control system, radio system, etc.) to be carried by the train; this must be compatible with the infrastructure to enable traction, control and communications from the train to IM control,
- train related data for the journey section: max. weight, max. length, max. speed, max. axle weight, min. brake force, max. weight per metre, information concerning exceptional gauging, identifiers of not allowed dangerous goods,
- path number,
- additional route section running time to allow for recovery, path problems, etc.

Execution path contract: before the running of a train, the journey section must be updated and completed with actual values. The execution mode is independent from the planning mode.

Path request on short notice

Due to exceptions during the train running or due to transport demands on a short-time basis, a railway undertaking must have the possibility to get an ad hoc path on the network.

In the first case, immediate actions have to be started, whereby the actual train composition based on the train composition list is known.

In the second case, the railway undertaking must provide the infrastructure manager with all necessary data concerning when and where the train is required to run together with the physical characteristics in so far as they interact with the infrastructure. These data are mainly given in the supplemented consignment note respectively in the wagon orders.

The path agreement for a train movement at short notice is based on a dialogue between RUs and IMs. The dialogue will involve all RUs and IMs involved in moving the train along the desired path but maybe with different contribution to the path finding process. According to Directive 2001/14/EC, Article 13, mainly two general valid different scenarios can be distinguished for freight transport operating on the infrastructures of several IMs (see also Annex A, Index 5, Chapter 1.3).

scenario A: The RU contacts all involved IMs directly (case A) or via the OSS (case B) to organise the paths for the complete journey. In this case the RU has also to operate the train on the complete journey according to Article 13 of the Directive 2001/14/EC.
scenario B: Each RU involved in the transport journey contacts the local IMs directly or via OSS to request a path for the journey section on which it operates the train.

remark: As already mentioned in Chapter 2 (Definition of subsystem/scope), in the execution mode, the IM will always communicate with the RU which has booked the path. Therefore the ‘path ownership’ is important for the message exchange during operation of the train.

In both scenarios the booking procedure of a path on short notice follows the dialogue between RU and IM involved as described on the next page.

The following table shows the messages used in the dialogue for the path request:

Table 1Path request

Message	Explanation
Messages used in the dialogue for the path request
Path Request	RU to IM(s) involved, this message must be sent for a path request at short notice.
Path Details	This message must be sent from IM(s) to RU confirming details of path in response to RU's ‘Path Request’, perhaps with changed values or if the IM cannot serve the path request, with the indication ‘No alternatives available’.
Path Confirmed	This message must be sent from the RU to the IM for the acceptance of the ‘Path Details’ from the IM in response to the RU's original request.
Path Details Refused	This message must be sent from the RU to the IM when not accepting the ‘Path Details’ from the IM in response to RU's original request, if there are changed values, which the RU cannot accept.

This dialogue ends with the RU by the Path Confirmed message or with the deletion of the path request (Path Request message with status ‘Deletion’, see Chapter 4.2: Functional and technical specifications of the subsystem, General remarks on the message structure). A Path Details Refused message from the RU must always be served with a new Path Details message. If the IM cannot serve the path request with a new proposal within the Path Details message, he must send the Path Details message with the indication ‘No alternatives available’, which ends the dialogue with the IM.

Whether the path was booked in the long-term planning or on a short notice, the RU must have always the possibility to cancel a booked path. For the cancellation of a booked path the following message must be used.

Table 2Path cancellation by RU

Message	Explanation
Message to cancel a booked path by RU
Path Cancelled	Advice from the RU to the IM to cancel a previously booked path or a part of it.

Based on the path agreement, the RU can expect that a booked path is also available. Therefore if something occurs and the booked path is no longer available, the IM must inform the RU as soon as it has the knowledge about this fact. A cause of this may be for example an interruption on the path. This can happen at any time between the moment the train path is contracted and the departure of the train. The IM is obliged to send an alternative proposal together with the indication ‘Path not available’. If this is not possible the IM must send the proposal as soon as possible. With the Path Not Available message a dialogue starts for a new path agreement initiated by the IM.

Messages used in the dialogue for the cancellation of a booked path by IM.

Table 3Path cancellation by IM

Message	Explanation
Messages used in the path cancellation process initiated by IM
Path Not Available	Advice from the IM to the RU that the booked path is not available.
Path Details	This message must be sent from IM(s) to RU proposing an alternative path after the advice from the IM to the RU that the booked path is not available.
Path Confirmed	This message must be sent from the RU to the IM for the acceptance of the path proposed in the Path Not Available message.
Path Details Refused	This message must be sent from the RU to the IM when not accepting the proposal from the IM in the Path Not Available message. In this case the IM must send a new proposal. This dialogue ends by the RU with the Path Cancelled message related to IM's Path Not Available message.

In general, if the receiver of a request or enquiry can not answer in real time he must inform the originator of the message (for example the Path Details message as response to the Path Request can not be sent immediately). This must be done by using the following message:

Table 4Receipt confirmation

Message	Explanation
This message is valid in general
Receipt Confirmation	This message must be sent from the recipient of a message to the originator of the message when the required response cannot be made available within the time interval as defined in Chapter 4.4 (Operating rules), section ‘Timeliness’.

These messages are described by mentioning the main points in the following chapters. The detailed formats are defined in Annex A, Index 1. The logical sequence of these messages is shown in the diagrams in Annex A, Index 5, Chapter 2.1 to 2.3.

4.2.2.2.Path Request message

This is the request from the RU to the IM for a train path. Such a request must contain:

path departure point: place from where the proposed path will start,
path departure date/time: date/time for which the path is requested,
path destination point: destination of train for the requested path,
path destination arrival date/time: date/time at which the proposed train is due to arrive at its destination,
requested journey section:
- intermediate stops or other designated points along the proposed path with date/time at which the proposed train is due to arrive at an intermediate point and the date/time that the train is due to depart from an intermediate point. A blank entry indicates that it will not stop at that point,
- available equipment on the train: traction type, command and control system including on-board radio equipment,
- train weight,
- train length,
- braking system to be used and braking performance,
- maximum speed of the train,

- responsible IM: identification of the IM responsible for the train for the current journey section,
- next responsible IM: identification of the IM responsible for the train for the next journey section (if any).

As an information support for the formulation of the path request, the RU can consult the relevant Network Statement to check whether the data of the train in mind comply with the infrastructure. Data such as dangerous goods information also has to be taken into account.

The keepers of the wagons must give the RUs access to the technical wagon data.

The RUs must themselves ensure access to the reference files, e.g. to the dangerous goods reference file if required.

4.2.2.3.Path Details message

This message is the answer from an IM to the Path Request message from an RU. In the case that the IM cannot serve the path request, he must send this message with the indication ‘No alternatives available’. In the other case he must answer the RU request by sending back a path number together with the same data as in the train path request but perhaps with changed values.

For the alternative proposed by IM the following data must be sent:

new path number,
path departure point: place from where the proposed path will start,
path departure date/time: date/time for which the path is proposed,
path destination point: destination of train for the proposed path,
path destination arrival date/time: date/time at which the train is due to arrive at its destination,
modified journey section:
- intermediate stops or other designated points along the proposed path with date/time at which the proposed train is due to arrive at an intermediate point and the date/time that the train is due to depart from an intermediate point. A blank entry indicates that it will not stop at that point,
- required equipment on the train: traction type, command and control system including on-board radio equipment,
- train weight,
- train length,
- braking system to be used and braking performance,
- maximum speed of the train,
- maximum axle weight of the train,
- maximum weight per metre,
- information concerning exceptional gauging,
- UN/RID numbers relating to any dangerous goods,
- definitions of activity to be undertaken at any intermediate point en route,
- responsible RU: identification of the RU responsible for the train for the current journey section,
- responsible IM: identification of the IM responsible for the train for the current journey section,
- next responsible IM: identification of the IM responsible for the train for the next journey section (if any).

4.2.2.4.Path Confirmed message

This message must be sent from an RU to an IM accepting a proposed path in response to the RU's original request. With this message the path is booked. The main message content is:

path number: to identify the path,
path departure point: place from where the train will depart,
path departure date/time: date/time for which the path is requested,
path destination point: train destination for the requested path,
path destination arrival date/time: date/time at which proposed train is due to arrive at its destination,
indicates that the RU has accepted the proposed path.

4.2.2.5.Path Details Refused message

In the case of a refusal of the proposed path as given in the Path Details message by the IM, the RU must send this message to the IM to advise him, that it does not accept the proposed path as given in the Path Details message. The main data are:

path number: to identify the path,
indicates the refusal of the path details.

As additional information the following data may be sent:

path departure point: place from where the train will depart,
path departure date/time: date/time for which the path is requested,
path destination point: destination of train for the requested path,
path destination arrival date/time: date/time at which the proposed train is due to arrive at its destination.

4.2.2.6.Path Cancelled message

This is the RU advice to cancel a previously booked path. Together with the cancellation indicator (corresponds to the message type), the path number must be sent for the unique identification of the path. This applies to path booking in planning mode and on short notice:

path number: to identify the path,
train number (if already known to the IM),
indicates the cancellation of the booked train path.

As additional information the following data may be sent:

path departure point: place from where the train will depart,
path departure date/time: date/time for which the path is requested,
path destination point: destination of train for the requested path,
path destination arrival date/time: date/time at which the proposed train is due to arrive at its destination.

4.2.2.7.Path Not Available message

The IM must inform the RU as soon as it has the knowledge, that a train path is not available. The message Train Path Not Available can be send at any time between the moment the train path is contracted and the departure of the train. A cause of this message may be e.g. an interruption on the path. The main contents of this message are:

path number of the path which is not available,
train number of the train foreseen for the cancelled path (if already known to the IM),
path departure point with date and time for which path was booked,
path destination point with date and time at which the train is due to arrive at its destination,
Train Path Not Available indication,
indication of the cause.

Together with this message or as soon as possible the IM must send without any further request from the RU an alternative proposal. This is done with the message Path Details related to this Path Not Available message.

4.2.2.8.Receipt Confirmation message

This information must be sent from the recipient of a message to the originator of the message, when the required response cannot be made available within the time-frame as specified in Chapter 4.4 (Operating rules). This message must have an identifier to which it refers (entries in Related message, see Chapter 4.2: Functional and technical specifications of the subsystem, General remarks on the message structure) and the indication: (Application level)

Message Confirmation: indicates that the recipient has received the message and will act upon it as necessary.

4.2.3.Train preparation

4.2.3.1.General remarks

This section specifies the messages which must be exchanged during the train preparation phase until the start of the train. The messages are shown below in Table 5.

For the preparation of the train, the RU must have access to the infrastructure restriction notices, to the technical wagon data (Rolling Stock Reference Databases, Chapter 4.2.11.3: The Rolling Stock Reference Databases), to the dangerous goods reference file and to the current, updated information status on the wagons (Chapter 4.2.12.2: Other databases : The Wagon and Intermodal Unit Operational Database). This applies to all wagons on the train. At the end the RU must send the train composition to the next RUs. This message must also be sent from the RU to the IM(s) with whom it has booked a path section, when requested by the Conventional Rail TSI Operation and Traffic Management or by the contract(s) between RU and IM(s).

If the train composition is changed at a location, this message must be exchanged once more with information updated by the RU responsible.

At each point, e.g. origin and interchange point, where the responsibility changes on the RU side, the start procedure dialogue between IM and RU ‘Train Ready — Train Running Information’ is obligatory.

The messages used within this start procedure dialogue are:

TABLE 5Train preparation

Message		Explanation
Train Composition		RU to IM, this message must be sent according the description above.
	In the case that the IM has received a train composition message send mandatory by the RU, the IM may send:
	Train Accepted	IM to RU: this message is optional, if nothing else is agreed between IM and RU.	Train preparation can be completed.
	Train Not Suitable	IM to RU: this message may be sent by the IM, if this is detected by him.	RU possibilities: modify the train composition, or cancel train path and request new path .
Train Ready		RU to IM: this message must be sent.
Train Position		IM to RU: defines exactly where and when the train must present itself on the network. This message may be sent depending on national rules.
Train at Start		RU to IM: this message may be sent to indicate that the train has started its journey as response on the message: Train Position. This message may be sent depending on national rules.
Train Running Information		IM to RU: this message must be sent to indicate that the train has arrived on the infrastructure.

These messages are described by mentioning the main points in the following chapters. The detailed formats are defined in Annex A, Index 1. The logical sequence is shown in Annex A, Index 5, Chapter 3.

Remark: During the train preparation also a Train Path Not Available message can occur, since this message can be send at any time between the moment the train path is contracted and the departure of the train. The procedure for this is described in Chapter 4.2.2 (Path request).

4.2.3.2.Train Composition message

This message must be sent from the RU to the next RU, defining the composition of the train. This message must also be sent from the RU to the IM(s) when requested by the Conventional Rail TSI Operation and Traffic Management or by the contract between IM and RU. Whenever there is a change in the composition during the journey of a train, the RU responsible has to update this message to all parties involved.

The information, which must be transmitted and be accessible, is:

train number and path number to identify the path,
path departure point and date and time for which the path was requested,
path destination point and date and time at which the proposed train is due to arrive at its destination,
loco(s) identification and position of loco(s) in the train,
train length, train weight, maximum speed of the train,
train composition with the sequence of vehicle IDs,
command and control system including type of radio equipment,
information concerning exceptional gauging,
UN/RID numbers of dangerous goods,
indication if livestock and people (other than the train crew) will be carried,
braking system to be used,
wagon data.

After the receipt of the train composition the IM may verify the entries against the contracted path, if the contract between IM and RU explicitly allows this. In that case the IM must have easy access to the information about possible restrictions in the relevant infrastructure, to the technical wagon data (Chapter 4.2.11.3: The Rolling Stock Reference Databases), to the dangerous goods reference file and to the current, updated information status on the wagons (Chapter 4.2.12.2: Other databases, Wagon and Intermodal Unit Operational Database). This refers to all wagons on the train. In that case also, the IM, who manages his train paths and keeps up the actual status of the path information, must add the train details of the train composition to the path and train data as mentioned in Chapter 4.2.2.1 (Path request, Preliminary remarks).

4.2.3.3.Train Accepted message

Depending on the contractual agreement between the IM and the RU and on regulatory requirements, the IM may also advise the RU if the train composition is acceptable for the booked path. This is effected with this message.

The main contents of this message are:

train and path number,
path departure point with date and time for which the path was requested,
path destination point with date and time at which the proposed train is due to arrive at its destination,
indication that the IM has accepted the train composition as being suitable for the agreed path.

4.2.3.4.Train Not Suitable message

If the train is not suitable for the previously agreed path, the IM may inform the RU, with this message. In this case the RU must recheck the train composition. The main contents of this message are:

train and path number,
path departure point with date and time for which the path was requested,
path destination point with date and time at which the proposed train is due to arrive at its destination,
Not Suitable indication, which indicates that the train does not match the allocated path and therefore may not run,
indication of the cause.

4.2.3.5.Train Ready message

This message must be sent from RU to IM indicating that the train is ready for access to the network. The main contents of this message are:

train and path number,
path departure point with date and time for which the path was requested,
path destination point with date and time at which the proposed train is due to arrive at its destination,
Train Ready indication, which indicates that the train has been prepared and is ready to run,
control contact ID for all ship-to-shore communications,
if the contractual arrangement between RU and IM does not require the Train Position/Train at Start message exchange, the train journey start date/time, which informs the IM of the forecasted date/time at which the train will present itself to the network, must be defined in this message. In the case of the required message exchange Train Position/Train at Start, this data element must not be transmitted.

4.2.3.6.Train Position message

This message may be sent from the IM to the RU defining exactly when and where the train should present itself to the network as an answer to the Train Ready message. The transmission of this message depends on the contractual arrangement between the RU and the IM. In case where the transmission is needed, the main contents of this message are:

train and path number,
path departure point with date and time for which the path is requested,
path destination point with date and time at which the proposed train is due to arrive at its destination,
track identification, which informs the RU of the track ID on which the train should present itself to the network,
train journey start date/time, which informs the RU of the precise date/time at which the train should present itself to the network,
control contact ID.

4.2.3.7.Train at Start message

This message may be sent from the RU to the IM when having received a Train Position message from the IM, to indicate that the train has started its journey. This message must have an identifier to which it refers and the indication:

Train at Start: date/time train actually started journey.

4.2.3.8.Train Running Information

As soon as the train is present on the IM infrastructure, which means that the train has left the departure station, the IM sends this message to the RU who has booked the path. This message is described in Chapter 4.2.4 (Train running forecast).

4.2.4.Train running forecast

4.2.4.1.General remarks

This section specifies the messages which must be exchanged during the normal running of a train without any interruption.

The relevant messages are:

Train Running Forecast,
Train Running Information.

This information exchange between RUs and IMs always takes place between the IM in charge and the RU, who has booked the path on which the train is actually running. In the case of Open Access, which means that the paths for the complete journey are booked by one RU (this RU also operates the train during the complete journey), all messages are sent to this RU. The same is true, if the paths for the journey are booked by one RU via OSS.

For further consideration the following scenarios will be differentiated, taking into account the various communication relations between RUs and IMs according to the path booking scenarios of Chapter 4.2.2.1 (Path request, Preliminary remarks, Scenario A and B):

Train approaching a handover point between IM n1 and his neighbour IM n2

It is supposed that the handover point is not also an interchange (only Scenario B) nor a handling point. Thus, the handover point is a point on the booked paths of one RU and the RU has already sent the train composition to IM n2, whilst simultaneously sending this message to IM n1.

IM n1, after departure from the departure point(5), must send a Train Running Forecast message to IM n2 with the estimated handover time (ETH). This message is simultaneously sent to the RU.

When the train leaves the infrastructure of IM n1 at the handover point this IM sends a Train Running Information with the actual handover time at this point to its path contracted RU.

When the train arrives on the infrastructure of IM n2 at the handover point this IM sends a Train Running Information with the actual handover time from this point to its path contracted RU.

Train approaching an interchange point between RU 1 and the next RU 2 (only Scenario B)

In the path contract an interchange point must always be defined as a reporting point. (TETAs at reporting points will be generated by the IMs as specified in their contracts with the RUs.)

For this point the IM in charge sends, once the train left the previous reporting point, a Train Running Forecast message with the TETA for this interchange point to the RU which has contracted the path with him (e.g. RU 1). RU 1 transfers this message to the next RU (e.g. RU 2) supposed to take over the train. Additionally, this message is also sent to the Lead RU (LRU) for the transport if there is one and if this is defined in the cooperation contract between both RUs.

If the interchange point is also a handover point between e.g. IM n1 and IM n2, IM n1 sends the Train Running Forecast message already after departure from the departure point or from the previous interchange point to IM n2 with the estimated handover time (ETH). This message is also sent to the RU having contracted the path e.g. RU 1. For the RU the ETH is equal to the TETA at the interchange point. RU 1 transfers this message to its neighbour RU 2 and to the Lead RU for the transport if there is one and if this is defined in the cooperation contract between both RUs.

When the train arrives at an interchange point, the IM must send a Train Running Information to his path contracted RU, for example RU 1, with the actual time of the arrival at that point.

Before the train leaves the interchange point, RU 2 must send a new Train Composition message to the IM having allocated the path and follow the departure procedure as defined in Chapter 4.2.3 (Train preparation).

Train approaching a handling point of an RU (Scenario A)

A handling point must always be defined in the path contract as a reporting point.

For this point the IM in charge must send a Train Running Forecast message with a TETA only if this is specified in contract between IM and RU.

But if the handling point is also a handover point between, for example, IM n1 and IM n2, IM n1 must send the Train Running Forecast message after departure from the departure point or from the previous interchange to IM n2 with the estimated handover time (ETH). This message is also sent to the RU. For the RU the ETH is equal to the TETA at the handling point.

When the train arrives at the handling point, the IM must send a Train Running Information with the actual time of arrival at this point to the RU.

Before the train leaves the handling point the RU and IM must follow the departure procedure as defined in Chapter 4.2.3 (Train preparation).

Train arrival at destination

When the train arrives at its destination the IM responsible sends a Train Running Information message with the actual arrival time to the RU which contracted the path.

Remark: In the path contract other locations may also be defined for which a Train Running Forecast with TETA and Train Running Information messages with the actual time are requested. For these points the IM in charge sends these messages as specified in the contract. The further evaluation and processing of the delivered ETHs and TETAs is described in the Chapters 4.2.7 (Shipment ETI/ETA) to 4.2.9 (Interchange reporting).

In the following chapters the message Train Running Forecast and Train Running Information are described by mentioning only the main contents. The detailed formats are defined in Annex A, Index 1. The logical sequence of this message exchange relating to the different communication scenarios is shown in Annex A, Index 5, Chapter 4 with the remark, that regarding the communication relation between RU and IMs for train running, the two path request scenarios A(case A) and A(case B) (Chapter 4.2.2.1: Path request, Preliminary remarks) are identical, because in both cases the IMs know only one RU e.g. RU1 which operates the complete path and is also responsible for new train composition at the handling points.

4.2.4.2.Train Running Forecast message

This message must be issued by the IM for handover points, interchange points and for the train destination as described in Chapter 4.2.4.1 (Train running forecast, General remarks).

In addition, the message must be issued by the IM to the RU for other reporting points according the RU/IM contracts (e.g. for handling points).

The main data elements are:

path number and train number,
scheduled departure date and time at IM location (or scheduled handover time to next IM),
reporting point identification,
forecasted date/time at reporting point.

4.2.4.3.Train Running Information message

This message must be issued upon:

departure from departure point, arrival at destination,
arrival and departure at handover points, interchange points and at agreed reporting points based on contract (e.g. handling points).
The main data elements are:
- path number and train number,
- scheduled departure date and time at IM location,
- most recent reporting point identification,
- actual time at reporting point,
- train reporting point status (Arrival, Departure, Passage, Not Specified, Departure from Origin, Arrival at Destination),
- arrival track at location,
- departure track from location,
- booked scheduled time delta deviation minutes,
- current schedule if multiple re-schedules,
- For each deviation from ‘Booked Scheduled Time’ at that reporting location:
  - reason code (perhaps multiple),
  - deviation time for this reason code (multiple reasons may be posted per reporting point),
  - may add free text about deviation.

4.2.5.Service disruption information

4.2.5.1.General remarks

When the RU learns about a service disruption during the train running operation for which it is responsible, it must immediately inform the IM concerned (no IT-message, e.g. orally by the driver). If necessary the RU updates the Wagon and Intermodal Unit Operational Database. If necessary the IM updates the infrastructure data in the Infrastructure Restriction Notice Database and/or the path, respectively the train database.

If the delay exceeds x minutes (this value must be defined in the contract between RU and IM) the IM concerned must send to the RU a Train Running Forecast message relating to the next reporting point.

If the train is cancelled, the IM sends a Train Running Interrupted message as specified below.

In the cases of exceptions where the RU or the IM is not able to run the train at the forecasted time, a new path according Chapter 4.2.2 (Path request) must be negotiated.

4.2.5.2.Train Running Interrupted message

If the train is cancelled this message is issued by the IM to the neighbouring IM and to the path contracted RU.

The main data elements in this message are:

path and train number,
location identification,
scheduled departure date and time at this location,
interruption reason,
interruption description.

4.2.6.Train location

4.2.6.1.Preface

This section specifies the tracing possibility to get information about train location. The RU may send an enquiry to the IM about its trains at any time. The RU may enquire about:

the running of the train (last recorded location, delays, delay reasons),
a train's performance (delays, delay reasons, delay locations),
all identifiers of a specified train,
train forecast at a specified location,
all train running forecasts for a specified location.

The access to this information must be independent from the communication relation RU/IM during the train running, which means that the RU must have a single(6) access address to this information. The information is based mainly on the stored message exchange as mentioned above.

4.2.6.2.Enquiry about the Train Running messages

Purpose

RU to enquire on the last recorded status (location, delays and delay reasons) of one specific train on the infrastructure of a specified IM.

Enquiry

main data elements:

train running number,
IM identifier,
scheduled departure date and time at IM location.

Response

information data:

most recent reporting location,
actual time at reporting point,
train reporting point status (Arrival, Departure, Passage, Not Specified, Departure from Origin, Arrival at Destination),
arrival track at location,
departure track from location,

booked scheduled time delta delay,
re-scheduled time (against current schedule if multiple re-schedules),
for each delay at that reporting location:
- reason code and delay time for this reason code.

4.2.6.3.Enquiry about the Train Delay/Performance messages

Purpose

4.2.7.Shipment ETI/ETA

4.2.7.1.Preliminary remark

The Chapters 4.2.2 (Path request) through to 4.2.6 (Train location) have mainly described the communication between the RU and the IM. Since the task of the infrastructure manager is the monitoring and control of the trains the key element for this communication is the train number. The wagon information part of the train composition message is relevant for checking the train composition against the IM/RU path-contract and in cases of exceptions.

The individual monitoring of wagons or intermodal units is not covered by this information exchange. This is done on the RU/LRU level based on the train related messages and is described in the following Chapters 4.2.7 (Shipment ETI/ETA) to 4.2.9 (Interchange reporting).

The wagon or intermodal unit related information exchange and updating are essentially supported by storage of ‘trip plans’ and ‘wagon movements’ (Chapter 4.2.12.2: Other databases).

As already mentioned in Chapter 2.3.2 (Considered processes), for a customer the most important information is always the estimated time of arrival (ETA) for his shipment. The wagon related ETA as well as the ETI is also the basic information in the communication between LRU and RU. This information is the main instrument for the LRU to monitor the physical transport of a shipment and to check it against the commitment to the customer.

The forecasted times in the train related messages are all related to an arrival of a train at a certain point, which may be a handover point, interchange point, the train destination or another reporting point. These are all Train Estimated Times of Arrivals (TETA). For the various wagons or intermodal units in the train, such a TETA may have different meanings. A TETA for an interchange point, for example, may be an estimated time of interchange (ETI) for some wagons or intermodal units. For other wagons remaining in the train for further transportation by the same RU, the TETA might have no relevance. It is the task of the RU receiving the TETA information to identify and process that information, store it as a wagon movement in the Wagon and Intermodal Unit Operational Database and communicate it to the LRU, if the train is not running in Open Access mode. This is now considered in the following chapters.

4.2.7.2.ETI/ETA calculation

The ETI/ETA calculation is based on the information from the infrastructure manager in charge, which sends, within the Train Running Forecast message, the Train Estimated Time of Arrival (TETA) for defined reporting points (in any case for handover, interchange, or arrival points including intermodal terminals) on the agreed train path e.g. for the handover point from one IM to the next IM (in this case TETA is equal to ETH).

For the interchange points or for other defined reporting points on the agreed train path, the RU must calculate for the next RU in the transport shipment chain, the estimated time of interchange (ETI) for the wagons and/or intermodal units.

As an RU may have wagons with different journeys and from various LRUs within the train, the interchange point for the ETI calculation for the wagons may be different. This is explained in the following two simplified examples (The pictorial representation of these scenarios is given in Annex A, Index 5, Chapter 1.4 and the sequence diagram based on example 1 for the interchange point C is shown in Annex A, Index 5, Chapter 5).

Example 1

RU 1 has wagons No 1 and 2 from LRU 1 and wagons No 3 to 5 from LRU 2 within the same train. At the interchange point C the further transport of the wagons 1 and 2 will be done by RU 2 and for the wagons 3 to 5 by RU 3. In this case RU 1 must calculate related to the interchange point C the ETI for the wagons 1 and 2 and must send these values to LRU 1. RU 1 must also calculate related to the same interchange point C the ETI for the wagons 3 to 5 and send these values to LRU 2.

Example 2

RU 1 has wagons No 1 and 2 from LRU 1 and wagons No 3 to 5 from LRU 2 within the same train. At the interchange point C the further transport of the wagons 3 to 5 will be done by RU 3 whereas the wagons 1 and 2 remain in the train of RU 1 until the interchange point E, where the responsibility for these wagons will be changed to RU 2. In this case RU 1 must calculate related to the interchange point C only the ETI for the wagons 3 to 5 and must send these values to LRU 2. For the wagons 1 and 2 the interchange point C is not relevant. The next relevant interchange point for these wagons is E and related to this point the RU 1 must calculate the ETI and send these values to LRU 1.

The next RU, based upon the ETI input of the preceding RU, calculates for its part the wagon related ETI for the next interchange point. These steps are effected by each succeeding RU. When the last RU (e.g. RU n) in the transport chain of a wagon receives the ETI from his preceding RU (e.g. RU n-1) for the interchange of the wagon between RU n-1 and RU n, the last RU (RU n) must calculate the estimated time of arrival of the wagons at the final destination. This is to cater for the placement of the wagons according to the wagon order and in line with the commitment of the LRU to his customer. This is the ETA for the wagon and must be sent to the LRU. It must be electronically stored along with wagon movement. The LRU must grant access to the customer for his relevant data, according to contractual conditions.

Remark on intermodal units: for the intermodal units on a wagon, the wagon ETIs are also ETIs for the intermodal units. Regarding the ETAs for intermodal units it should be noticed, that the RU is not in the position to calculate such an ETA beyond the rail transportation part. Therefore the RU can only deliver ETIs related to the intermodal terminal.

The Lead RU is responsible for the comparison of the ETA with the commitment to the customer.

Deviations of the ETA against the commitment to the customer must be handled in accordance with the contract and may lead to an alert management process by the LRU. For the transmission of information on the result of this process is foreseen the Alert message.

As a basis for the Alert management process the LRU must have the possibility for a wagon related enquiry on deviations. This enquiry of an LRU and the response from an RU is also specified below.

4.2.7.3.Wagon ETI/ETA message

Purpose

sending ETI or updated ETI from one RU to the next in the transport chain. The last RU in the transport chain of the wagons sends the ETA or updated ETA to the LRU.

Main data elements

RU identification which has produced the ETI or ETA,
departure or previous interchange station (ETI or departure time at origin station),
train number starting from departure or previous interchange station (from ETI or departure time at origin station),

Purpose

following the comparison between ETA and commitment to the customer, the LRU may send an Alert message to the RUs involved.

Main data elements

wagon number,
commitment to the customer: arrival date and hour,
actual ETA: date and time.

Remark: In case of Open Access the calculation of ETI and ETA is an RU internal process. In this case the RU is the lead RU itself.

Wagon Delivery Notice
Wagon Delivery Confirmation
Wagon Interchange Reporting, will be described separately in Chapter 4.2.9: Interchange reporting

4.2.8.2.Wagon Release Notice message

Purpose

LRU to RU: The Lead RU is not necessarily the first RU in the transport chain. In this case the LRU must tell the RU in charge that the wagon is ready for pull at the customer sidings (place of departure according to the LRU commitment) at the given release time (date and time of departure).

This event must be stored in the Wagon and Intermodal Unit Operational Database.

Main data elements

wagon number,
yard of departure identification,
date and time of departure from the yard.

4.2.8.6.Wagon Exception message

Purpose

The RU must inform the LRU if something unexpected occurs to the wagon, which might have an impact for the ETI/ETA, or requires any additional action. This message requires in most of the cases also a new ETI/ETA calculation. If the LRU decided to have a new ETI/ETA, it sends a message back to the RU, which has sent this message together with the indication ‘ETI/ETA requested’ (message: Wagon Exception message New ETI/ETA Request). The new ETI/ETA calculation must follow the procedure of Chapter 4.2.7 (Shipment ETI/ETA).

This information must be stored in the Wagon and Intermodal Unit Operational Database.

Main data elements

wagon number,
place, date and time of disruption (place where something unexpected happens during the transport),
reason/disruption code.

In addition the following data must be easily accessible as stored data in databases:

4.2.8.7.Wagon Exception message New ETI/ETA Request

Purpose

The LRU may send this message to the actual RU, which has sent the Exception message, to request for new ETI/ETA calculation. The LRU sends this message also to all following RUs to inform them about the deviations. The need for a new ETI/ETA calculation is up to the LRU and is not necessary in any cases.

Main data elements

wagon number,
place, date and time of disruption (place where something unexpected happens during the transport),
reason/disruption code,
new ETI/ETA request.

In addition the following data must be easy accessible as stored data in databases:

Main data elements

wagon number,
identification of placement on consignee sidings (location, zone, track, slot),
date and time of placement.

The Wagon Delivery Notice may be sent a second time as a Wagon Delivery Confirmation with the additional data:

customer identifier.

Remark: In the case of Open Access the described wagon movement is an RU (LRU) internal process. Nevertheless all calculations and data storage must be effected by it as the LRU having a contract with and a commitment to the customer.

The sequence diagram for these messages based on example 1 for the ETI calculation for the wagons 1 and 2 (see Chapter 4.2.7.2 ETI/ETA calculation) is integrated in the diagram for interchange reporting in Annex A, Index 5, Chapter 6.

4.2.9.Interchange reporting

4.2.9.1.Preliminary remark

The interchange reporting describes the messages attached to the transfer of responsibility for a wagon between two railway undertakings, which occurs at interchange points. It also commands the new RU to make an ETI calculation and to follow the process as described in Chapter 4.2.7 (Shipment ETI/ETA).

The following messages must be exchanged:

Wagon Interchange Notice,
Wagon Interchange Notice/Sub,
Wagon Received At Interchange,
Wagon Refused At Interchange.

The information data of these messages must be stored in the Wagon and Intermodal Unit Operational Database. In case of any deviation a new ETI/ETA must be generated and communicated according to the process described in Chapter 4.2.7: Shipment ETI/ETA . The sequence diagram for these messages is shown in connection with the wagon movement messages in Annex A, Index 5, Chapter 6.

The Wagon Interchange Notices and the Wagon Interchange Notices/Sub as well as the wagon received messages may be transferred as a list for various wagons, especially if these wagons are all within one train. In this case all the wagons may be listed within one message transfer.

In the case of Open Access there are no interchange points. At a handling point the responsibility for the wagons does not change. Therefore there is no special message exchange needed. But derived from the running information of the train at this reporting point, the wagon or intermodal unit related information — regarding location and date/time of arrival and departure — must be processed and stored in the Wagon and Intermodal Unit Operational Database.

The contents of these messages are given as follows:

4.2.9.2.Wagon Interchange Notice message

Purpose

With the Wagon Interchange Notice a railway undertaking (RU 1) asks the next railway undertaking (RU 2) in the transport chain whether it accepts the responsibility for a wagon. With the Wagon Interchange Notice/Sub the RU 2 informs its IM, that it has accepted the responsibility.

Main data elements

wagon number,
train number (only if the wagon is in a train),
location; date and time of interchange.

In addition the following data must be easily accessible as stored data in databases:

transportation unit identification (number, size, type),
total weight (booked/actual total weight (mass) of goods, including packing and carrier's equipment),
unit capacity used,
dangerous good details, ID.

4.2.9.3.Wagon Interchange Notice/Sub message

Purpose

With the Wagon Interchange Notice/Sub the RU 2 informs the IM, that it has taken over the responsibility of a particular wagon.

Main data elements

wagon number,
train number (only if the wagon is in a train),
location, date and time of interchange.

In addition the following data must be easily accessible as stored data in databases:

Main data elements

wagon number,
location, date and time of interchange,
reason code for the refuse,
further description (optional).

4.2.10.Data exchange for quality improvement

To be competitive the European Railway Industry must deliver higher service quality to its customers (see also Annex III, Article 2.7.1 to the Directive 2001/16/EC).

A measurement process is an essential post trip process to support quality improvements.

In addition to measuring the service quality delivered to the customer, LRUs, RUs and IMs must measure the quality of the service components that in total make up the product delivered to the customer.

The process involves the IMs and the RUs (especially if they are Lead RUs) selecting an individual quality parameter, a route or location and a measurement period in which actual results are to be measured against predetermined criteria and which normally have been set out in a contract.

The results of the measurement process must clearly show the achievement level against the target which has been agreed upon between the contracting parties.

The measurement reports must be able to access sufficient detail to allow an analysis to indicate the location and apparent cause of reductions in quality, e.g. delays. Root cause analysis must then be carried out on repetitive, quality failures, so that corrective action can be determined by the contracting parties.

It is the obligation of an IM and an RU to provide data, participate in root cause analysis, also with third parties, and to implement any corrective action which has been agreed to.

The measurement process is a repetitive one.

To measure quality the already defined messages may be used as shown under the six headings, listed below:

1. LRU/customer

Transit Time, ETA, Alert Resolution

In contracts between RUs acting as service integrators (LRU) and customers, commitments can be made (depending on the individual agreement) regarding transit time, ETA and alert resolution. The most relevant messages for this measurement of quality are:

Release Notice,
Departure Notice,
Delivery notice.

2. LRU/service providers

Transit and Handling Times, ETAs, ETIs, Reason Codes

In contracts between a Lead RU and other transport service providers commitments can be made concerning transit times (hours) with individual service providers as follows:

release cut off/pull time to interchange delivery,
pick up to in gate,
in gate to loading,
interchange receipt to interchange delivery,
interchange receipt to placement/constructive placement,
grounding to delivery.

The most relevant messages for this measurement of quality are:

Release Notice,
Departure Notice,
Yard Arrival,
Yard Departure,
Arrival Notice,
Wagon Interchange Delivery,
Wagon Interchange Receipt,
Wagon Interchange Refused.

3. RU/IM

Train Performance, Train ETA (TETA), ETH

In contracts between RUs and IMs, a punctuality level for train schedules at specified reporting points can be specified as can the accuracy of train ETAs and ETHs. The most relevant messages for this measurement of quality are:

Train Running Forecast,
Train Running Information,
Enquiry/Response about train delay/performance.

4. RU/IM

Path Availability/Planned

In contracts between RUs and IMs path availability to run trains will be clearly described in terms of a range of times at specified points. Train specifications in terms of maximum length and gross weight, loading gauge etc., will also be covered in these contracts. This aspect will be addressed under item number 6 (IM/RU: Train composition quality).

The procedures and time frames for confirming the utilisation of a path, cancelling the use of a planned path and the extent to which a path can be used outside (early or late) the specified range of times will also be covered in these contracts. The most relevant messages for this measurement of quality are:

Path Cancelled,
Path Not Available.

5. RU/IM

Path Availability on short notice

When an RU wants to run a train outside the time limits established for a planned path, a path request on short notice must be sent to the IM(s) involved (as provided in the Directive 2001/14/EC).

Periodically the RU will compare the path request and the response data for producing reports as follows:

path request response time against framework agreement,
number of paths supplied within certain time periods, within the requested time,
number of rejected path requests.

The most relevant messages for this measurement of quality are:

Path Request,
Path Details,
Path Details Refused,
Path Cancelled,
Path Not Available.

6. IM/RU

Train composition quality

When the train ready messages and/or train composition lists are sent by an RU to the IM(s) or to other RUs, they must comply with the train specifications contained within the applicable contract. For the checking of this compliance and therefore for the measurement of the train composition quality the most relevant messages are:

Train Composition,
Train Not Suitable.

4.2.11.The main reference data

4.2.11.1.Preface

The Infrastructure Data (the Network Statements and the stored data in the Infrastructure Restriction Notice Database) and Rolling Stock Data (in the Rolling Stock Reference Databases and in the Wagon and Intermodal Unit Operational Database) are the most important data for the operation of freight trains on the European network. Both types of data together allow an assessment of the compatibility of the rolling stock with the infrastructure, help to avoid multiple data input, which increase especially the data quality, and they give a clear picture on all available installations and equipment at any time for fast decisions during the operation.

4.2.11.2.The Infrastructure Restriction Notice Databases

Each IM is responsible for the suitability of a path on his infrastructure and the RU is obliged to check the train characteristics against the values given in the path details of its contracted path.

Without prejudice to the conditions for the usage of a path in the Network Statements or to the responsibilities in case of any restrictions in the infrastructure explained in the TSI Operation and Traffic Management, the RU must know before preparing the train, whether there are any restrictions on the line segments or stations (nodes) affecting its train composition described in the path contract.

For this the IMs must install and fill-in Infrastructure Restriction Notice Databases. The structure of such a database is outlined in Annex A, Index 2. The entries of these databases are based on segments in line with the relevant Network Statements with the addition of restriction information. These databases must be accessible via the common interface (4.2.14.1: General architecture and 4.2.14.7: Common interface).

The RU is obliged to take into account all restrictions in the Infrastructure Restriction Notice Database affecting its train running until the pre-departure period. If nothing else is defined in a contract between the IM and RU, the pre-departure period starts one hour before the scheduled time of departure.

In the pre-departure period the IM must notify directly the RU of any relevant changes arising in the Infrastructure Restriction Notice Database.

4.2.11.3.The Rolling Stock Reference Databases

The keeper of a rolling stock is responsible for the storage of the rolling stock data within a Rolling Stock Reference Database.

The Information that must be included in the individual Rolling Stock Reference Databases is described in detail in Annex A, Index 2. They must contain all items for:

identification of rolling stock,
assessment of the compatibility with the infrastructure,
assessment of relevant loading characteristics,
brake relevant characteristics,
maintenance data,
environmental characteristics.

The Rolling Stock Reference Databases must allow easy access (a single common access provided via the common interface) to the technical data to minimise the volume of data transmitted for each operation. Contents of the databases must be accessible, based on structured access rights depending on privilege to all service providers (IMs, RUs, logistic providers and fleet managers) in particular for purposes of fleet management and rolling stock maintenance.

The entries in the Rolling Stock Reference Database can be grouped as follows:

Administrative data,
related to certification and registration items such as reference to the EC registration file, ID of the notified body, etc.; this may include historical data related to ownership, rental, etc. The following steps have to be taken into account:
- EC certification,
- registration in the ‘home’ State,
- date put into service in the State of registration,
- registration in other countries for the use on their national network,
- safety certification for all rolling stock which does not comply with the Rolling Stock TSI.
The keeper is obliged to ensure that these data are available and the processes behind have been conducted.
Design data,
which shall include all constitutive (physical) elements of the rolling stock, including characteristics related to the environment, and all information that is expected to remain valid throughout the life of the rolling stock — this part may contain a history of major modifications, major maintenance, overhaul, etc.

4.2.11.4.The Rolling Stock Operational Data

Beside the reference data for rolling stock, the data representing the actual status of the rolling stock is the most important data for operational purposes.

This data shall include temporary data, such as restrictions, current and projected maintenance actions, kilometers and fault counters, etc.; and all data that could be considered as ‘status’ (temporary speed restrictions, brake isolated, needs for repair and fault description, etc.,).

For use of the operational rolling stock data, three different entities must be considered taking into account the different parties responsible for rolling stock during transport operation:

Railway Undertaking as Duty holder during its transport control,
Keeper of rolling stock, and
User (Hirer) of rolling stock.

For all three different parties the operational rolling stock data must be accessible by the authorised user, down to his predefined authorised level, using the single key given by the wagon ID (wagon number).

The operational rolling stock data is a part of the European-wide Wagon and Intermodal Unit Operational Database as described in Chapter 4.2.12.2 Other databases .

4.2.12.Various reference files and databases

4.2.12.1.Reference files

For the operation of freight trains on the European network the following reference files must be available and accessible to all service providers (IMs, RUs, logistic providers and fleet managers). The data must represent the actual status at all times.

Locally stored and administrated:

reference file of the emergency services, correlated to type of hazardous goods.

Centrally stored and administrated:

reference file of the coding for all IMs, RUs, service provider companies,
reference file of the coding for transport customers,
reference file of the coding of locations (primary, subsidiary and zone-track-spot),
reference file of the coding for customer locations,
reference file of all existing train control systems,
reference file of hazardous goods, UN and RID numbers,
reference file of all different locomotive types,
reference file of all CN and HS codes for goods,
reference file of all European maintenance workshops,
reference file of all European audit bodies,
reference file of all European licensed operators including respective list of national safety certificates granted.

The coding of IMs, RUs, transport organisations and companies and transport customers as well as of locations (primary, subsidiary, etc.) including customer locations are pending.

4.2.12.2.Other databases

To allow for the tracking of train and wagon movements, the following databases, updated at each relevant event in real time, must be installed. Authorised entities such as keepers and fleet managers must have access to the data relevant to fulfil their functions, according to contractual conditions.

Wagon and Intermodal Unit Operational Database,
Trip plan for wagon/intermodal unit.

These databases must be accessible via the common interface (4.2.14.1: General architecture and 4.2.14.7: Common interface).

Wagon and Intermodal Unit Operational Database

The communication between the Lead RU and RUs in the cooperation mode is based on wagon and/or intermodal unit numbers. Therefore an RU, which communicates with the IMs at train level, must break down this information into wagon and intermodal unit related one. This wagon and intermodal unit related information must be stored in the Wagon and Intermodal Unit Operational Database. The information on train movement leads to new entries/updates in the Wagon and Intermodal Unit Operational Database for customer information. The movement part for a wagon or intermodal unit in the database is set up at the latest when receiving the release time for the wagons or intermodal unit from the customer. This release time is the first movement entry for a wagon into the Wagon and Intermodal Unit Operational Database related to an actual transport journey. The messages for the wagon movement are defined in the Chapters 4.2.8 (Wagon movement) and 4.2.9 (Interchange reporting). This database must be accessible via the common interface (4.2.14.1: General architecture and 4.2.14.7: Common interface).

The Wagon and Intermodal Unit Operational Database is the most important one for the tracking of wagons and therefore for the communication between the RUs involved and the Lead RU. This database shows the movement of a wagon and of an intermodal unit from departure through to final delivery at customer sidings with ETIs and actual times at different locations until the final delivery time ETA. The database also shows the different status of the rolling stock such as:

Status: loading of the rolling stock

This status is required for the information exchange between the RU and the IMs and to other railway undertakings involved in the transport journey.

Status: loaded wagon on journey

This status is required for the information exchange between the IM and the RU, with other infrastructure managers and with other railway undertakings involved in the transport journey.

Status: empty wagon on journey

This status is required for the information exchange between the IM and the RU, with other infrastructure managers and railway undertakings involved in the transport journey.

Status: unloading of rolling stock

This status is required for the information exchange between the RU at destination and the Lead RU for the transport.

Status: empty wagon under fleet management control

This status is required to get the information about availability of a vehicle of defined characteristics.

Wagon Trip Plan Databases

Trains normally carry wagons from various customers. For each wagon the Lead RU (RU acting as service integrator) must establish and update a trip plan which corresponds to the train path at train level. New train paths for a train — e.g. in case of service interruptions — lead to revised trip plans for the wagons concerned. The creation time for the trip plan is the receipt of the consignment note from the customer.

The Wagon Trip Plans must be stored by each LRU in a database. These databases must be accessible via the common interface (4.2.14.1: General architecture and 4.2.14.7: Common interface).

Remark:

In addition to the mandatory databases mentioned above, at each IM side a train database may be installed.

This infrastructure manager train database corresponds to the movement part of the Wagon and Intermodal Unit Operational Database. The main data entries are the train related data of the train composition message from the RU. All train events result in an update of this train related database. An alternative storage possibility for these data is the path database (Chapter 4.2.2: Path request). These databases must be accessible via the common interface (4.2.14.1: General architecture and 4.2.14.7: Common interface).

4.2.12.3.Additional requirements on the databases

Under the following points are listed additional requirements which must be supported by the various databases.

These are:

Authentication

A database must support the authentication of users of the systems before they can gain access to the database.

Security

A database must support the security aspects in the meaning of controlling access to the database. The possible encryption of the database contents itself is not required.

Consistency

A database selected shall support the ACID principle (Atomicity, Consistency, Isolation, Durability).

Access control

A database must allow access to the data to users or systems that have been granted permission. The access control shall be supported down to a single attribute of a data record. The database shall support configurable, role based access control for insertion, update or deletion of data records.

Tracing

A database must support logging all actions applied to the database to allow for tracing the detail of the data entry (Who, What, When did the contents change).

Lock strategy

A database must implement a locking strategy which allows access to the data even when other users are currently editing records.

Multiple access

A database must support that data can be accessed simultaneously by several users and systems.

Reliability

The reliability of a database must support the required availability.

Availability

A database must have an availability on demand of at least 99,9 %.

10.

Maintainability

A maintainability of the database must support the required availability.

11.

Safety

Databases themselves are not safety related. Hence safety aspects are not relevant. This is not to be confused with the fact that the data — e.g. wrong or not actual data — may have impact on the safety operation of a train.

12.

Compatibility

A database must support a data manipulation language that is widely accepted, such as SQL or XQL.

13.

Import facility

A database shall provide a facility that allows the import of formatted data that can be used to fill the database instead of manual input.

14.

Export facility

A database shall provide a facility that allows to export the contents of the complete database or its part as formatted data.

15.

Mandatory fields

A database must support mandatory fields that are required to be filled before the relevant record is accepted as input to the database.

16.

Plausibility checks

A database must support configurable plausibility checks before accepting the insertion, update or deletion of data records.

17.

Response times

A database must have response times that allow users to insert, update or delete data records in a timely manner.

18.

Performance aspects

A database shall support the queries necessary to allow the effective run of about 60 000 train runs per 24 hours. About 50 % of these train runs are deemed to take place within two hours.

The number and kind of queries or updates per train are dependent on the overall process for planning and running a train.

19.

Capacity aspects

A database shall support the storage of the relevant data for all freight wagons respectively the network. It shall be possible to extend the capacity by simple means (i.e. by adding more storage capacity and computers). The extension of the capacity shall not require replacement of the subsystem.

20.

Historical data

A database shall support the management of historical data in the meaning of making of data available that has been already transferred into an archive.

21.

Back-up strategy

A back-up strategy shall be in place to ensure that the complete database contents for up to a 24-hour period can be recovered.

22.

Commercial aspects

A database system used shall be available commercially-off-the-shelf (COTS-product) or be available in the public domain (Open Source).

Remarks:

The above requirements must be handled by a standard Database Management System (DBMS).

The usage of the various databases is embedded into various work flows described here before. The general workflow is a request/response mechanism, where an interested party requests information from the database through the common interface (4.2.14.1: General architecture and 4.2.14.7: Common interface). The DBMS responds to this request either by providing the requested data or by responding that no data can be made available (no such data exists or access is refused due to access control).

4.2.13.Electronic transmission of documents

The description in Chapter 4.2.14 (Networking and communication) presents the communication network to be used for data exchange. This network and the described security handling allow any type of network transmission, such as e-mail, file transfer (ftp, http), etc. The type to choose can then be decided upon by the parties involved in the information exchange, which means, that the electronic transmission of documents, for example, via ftp is given.

4.2.14.Networking and communication

4.2.14.1.General architecture

This subsystem will see, over time, the growth and interaction of a large and complex telematic rail interoperability community with hundreds of participating actors (RUs, IMs, etc.), which will compete and/or cooperate in serving the market's needs.

The network and communication infrastructure supporting such rail interoperability community will be based on a common ‘Information Exchange Architecture’, known and adopted by all participating actors.

The proposed ‘Information Exchange Architecture’:

is designed to reconcile heterogeneous information models by semantically transforming the data that is exchanged between the systems and by reconciling the business process and application-level protocol differences,
has minimum impact on the existing IT architectures implemented by every actor,
safeguards IT investments made already.

The Information Exchange Architecture favours a mostly peer-to-peer type of interaction between all actors, while it guarantees the overall integrity and consistency of the rail interoperability community by providing a set of centralised services.

A peer-to-peer interaction model allows the best cost distribution between the different actors, based on actual usage and it will present, in general, lesser scalability problems. A pictorial representation on the general architecture is given in Annex A, Index 5, Chapter 1.5.

4.2.14.2.Network

Networking in this case means the method and philosophy of communication and does not mean the physical network.

Rail interoperability is based on a common ‘Information Exchange Architecture’, known and adopted by all participants, thus encouraging and lowering barriers for new entrants, especially customers.

The security issue will therefore be addressed not by the network (VPN, tunnelling, etc.), but by exchanging and managing inherently secure messages. A VPN network is therefore not required (the administration of a large VPN network will be complex and costly to manage), thus avoiding problems with responsibilities and ownership allocation. Tunnelling is not considered as a necessary means for achieving the appropriate security level.

In any case if some actors already have or want to implement various degrees of security on selected partitions of the network, they can do so.

Over the public Internet network it is possible to implement a hybrid peer-to-peer model with a ‘central repository’ and a ‘common interface’ at each actors' node.

The central repository is approached first to obtain meta-information, such as the identity of the peer (actor) on which some information is stored, or to verify security credentials. Afterwards, a peer-to-peer communication is performed between involved actors.

4.2.14.3.Protocols

Only protocols belonging to the full Internet Protocol suite must be used.

4.2.14.4.Security

To achieve a high level of security, all messages must be self-contained, which means that the information in the message is secured and the receiver can verify the authenticity of the message. This may be solved by using an encryption and signing scheme similar to email encryption. This makes it possible to use any type of network transmission, like e-mail, file transfer (ftp, http), etc. The actual type to choose can then be decided upon by the parties involved in the information exchange.

4.2.14.5.Encryption

Either asymmetric encryption or a hybrid solution based on symmetric encryption with public key protection must be used, due to the fact that sharing a common secret key among many actors will fail at some point. A higher level of security is easier to achieve if every actor takes responsibility for its own pair of keys, even though a high level of integrity of the central repository (the key server) is required.

4.2.14.6.Central repository

The central repository must be able to handle:

metadata — structured data describing the content of messages,
Public Key Infrastructure (PKI),
Certification Authority (CA),
directory (phonebook) — it contains all needed information about the participating actors for exchanging messages.

The management of the central repository should be under the responsibility of a non-commercial co-European organisation.

4.2.14.7.Common interface

The common interface is mandatory for each actor in order to join the rail interoperability community.

The common interface has to be able to handle:

message formatting of outgoing messages according to the metadata,
signing and encryption of outgoing messages,
addressing of the outgoing messages,
authenticity verification of the incoming messages,
decryption of incoming messages,
conformity checks of incoming messages according to metadata,
handling the single common access to various databases.

Each instance of the common interface will have access to all the data required according the TSI within each RU, IM, etc, whether the relevant databases are central or individual (see also Annex A, Index 5, Chapter 1.6).

Based on the results of authenticity verification of incoming messages, a minimum level of message acknowledgement can be implemented:

(i)

positive send ACK;

(ii)

negative send NACK.

The common interface uses the information in the central repository in order to manage the above tasks.

An actor may implement a local ‘mirror’ of the central repository to shorten response times.

4.3.Functional and technical specifications of the interfaces

In light of the essential requirements in Chapter 3, the functional and technical specifications of the interfaces are as follows:

4.3.1.Interfaces with the TSI infrastructure

The infrastructure subsystem includes traffic management, tracking, and navigation systems: technical installations for data processing and telecommunications intended for long-distance passenger services and freight services on the network in order to guarantee the safe and harmonious operation of the network and efficient traffic management.

The subsystem Telematic Applications for Freight uses the data required for operational purposes as given by the path contract, eventually updated in the restriction notice database, as provided by the IM. Thus no direct interface exists between this TSI and the TSI for infrastructure.

4.3.2.Interfaces with the TSI control/command and signalling

The only connection to control command and signalling is via the

path contract, where within the line segment description the relevant information about usable command control and signalling equipment is given, and
various Rolling Stock Reference Databases, where the command control and signalling equipment of the rolling stock must be stored.

4.3.3.Interfaces with the rolling stock subsystem

The subsystem Telematic Applications for Freight identifies the technical and operational data, which must be available for the rolling stock.

The rolling stock TSI specifies the characteristics of a wagon. If the characteristics changes for a wagon, this must be updated in the Rolling Stock Reference Databases within the normal maintenance process for the database. Thus no direct interface exists between this TSI and the TSI for rolling stock.

4.3.4.Interfaces with the TSI operation and traffic management

The subsystem Operation and Traffic Management specifies the procedures and related equipment enabling a coherent operation of the different structural subsystems, both during normal and degraded operation, including in particular train driving, traffic planning and management.

The subsystem Telematic Applications for Freight mainly specifies applications for freight services including real-time monitoring of freight and trains and the management of connections with other modes of transport.

In order to ensure consistency between both TSIs, the following procedure applies.

When the specifications of the TSI Operation and Traffic Management related to the requirements of this TSI will be written and/or will become subject to amendments, then the body in charge of this TSI must be consulted.

In the case that the specifications of this TSI related to operational requirements specified in the TSI Operation and Traffic Management should be subject to any amendment, the body in charge of the TSI Operation and Traffic Management must be consulted.

4.4.Operating rules

In light of the essential requirements in Chapter 3, the operating rules specific to the subsystem concerned by this TSI are as follows:

4.4.1.Data quality

For data quality assurance purposes, the originator of any TSI message will be responsible for the correctness of the data content of the message at the time when the message is sent. Where the source data for data quality assurance purposes is available from the databases provided as part of the TSI, the data contained within those databases must be used for data quality assurance.

Where the source data for data quality assurance purposes is not provided from the databases provided as part of this TSI, the originator of the message must make the data quality assurance check from their own resources.

Data quality assurance will include comparison with data from databases provided as part of this TSI as described above plus, where applicable, logic checks to assure the timeliness and continuity of data and messages.

Data are of high quality if they are fit for their intended uses, which means they:

are error-free: accessible, accurate, timely, complete, consistent with other sources, etc., and
possess desired features: relevant, comprehensive, proper level of detail, easy-to-read, easy-to-interpret, etc.

The data quality is mainly characterised by:

accuracy,
completeness,
consistency,
timeliness.

Accuracy:

The information (data) required needs to be captured as economically as possible. This is only feasible if the primary data, which plays a decisive role in the forwarding of a consignment, a wagon or a container, is only recorded, if possible, on one single occasion for the whole transport. Therefore the primary data should be introduced into the system as close as possible to its source, e.g. on the basis of the consignment note drawn up when a wagon or a consignment is tendered for carriage, so that it can be fully integrated into any later processing operation.

Completeness:

Before sending out messages the completeness and syntax must be checked using the metadata. This also avoids unnecessary information traffic on the network.

All incoming messages must also be checked for completeness using the metadata.

Consistency:

Business rules must be implemented in order to guarantee consistency. Double entry should be avoided and the owner of the data should be clearly identified.

The type of implementation of these business rules depends on the complexity of the rule. For simple rules, database constraints and triggers are sufficient. In case of more complex rules which require data from various tables, validation procedures must be implemented which check the consistency of the data version before interface data are generated and the new data version becomes operational. It must be guaranteed that transferred data are validated against the defined business rules.

Timeliness:

The provision of information right in time is an important point. As far as the triggering for data storage or for message sending is event driven directly from the IT system the timeliness is not a problem if the system is designed in well manner according the needs of the business processes. But in most of the cases the initiation of sending a message is done by an operator or at least is based on additional input from an operator (for example the sending of the train composition or the actualising of train or wagon related data). To fulfil the timeliness requirements the updating of the data must be done as soon as possible also to guarantee, that the messages will have the actual data content when sending out automatically by the system.

In general the following requirements must be fulfilled:

The response time for enquiries must be less then 5 minutes. All data updates and exchanges must be done as soon as possible. The system reaction and transmission time for the update should be below 1 minute.

Data quality metrics

For the completeness (percent of data fields having values entered into them) of mandatory data and for the consistency of data (percent of matching values across tables/files/records) a percentage of 100 % must be reached.

For the timeliness of data (percent of data available within a specified threshold time frame) a percentage of 98 % must be reached. As far as threshold values are not defined in this TSI, these values must be specified in the contracts between the involved parties.

The required accuracy (percent of stored values that are correct when compared to the actual value) must be above 90 %. The exact value and the criteria must been set out in the contracts between the involved parties.

4.4.2.Operating the central repository

The functions of the central repository are defined in Chapter 4.2.14.6 (Central repository). For data quality assurance purposes, the entity operating the central repository should be responsible for the updating and the quality of the metadata and the directory, and also for the administration of the access control (Public keys). Regarding the quality of the metadata a percentage of 100 % must be reached for completeness, consistency, timeliness and accuracy.

4.5.Maintenance rules

In light of the essential requirements in Chapter 3, the maintenance rules specific to the subsystem concerned by this TSI are as follows:

The quality of the transport service must be guaranteed even if the data processing equipment were to break down in full or in part. It is therefore, advisable to install duplex systems or computers with a particularly high degree of reliability, and for which the uninterrupted operation during maintenance is ensured.

The maintenance aspects regarding the various databases are mentioned in Chapter 4.2.12.3 (Additional requirements on the databases), points 10 and 21.

4.6.Professional qualifications

The professional qualifications of staff required for the operation and maintenance of the subsystem and for implementing the TSI are as follows:

The implementation of this TSI does not require a complete new system in hardware and software with new staff. The realisation of the requirements of the TSI leads only to changes, upgrades or functional enlargements of the operation as it is already done by the existing staff. Therefore, there are no additional requirements to the existing national and European rules on professional qualifications.

If necessary, an add-on training of staff should not just consist of showing them how to operate equipment. The member of staff must know and understand his specific role to be played in the overall transportation process. Staff must in particular be aware of the requirement to maintain a high working performance level, since this is a decisive factor for the reliability of the information to be processed at a subsequent stage.

The professional qualifications needed for the composition and operation of trains are defined in the TSI Operation and Traffic Management.

4.7.Health and safety conditions

The health and safety conditions of staff required for the operation and maintenance of the subsystem concerned (or the technical scope as defined in paragraph 1.1) and for the implementation of the TSI are as follows:

There are no additional requirements to existing national and European rules on health and safety.

4.8.Infrastructure and rolling stock registers

In accordance with Article 24(1) of Directive 2001/16/EC, ‘the Member States shall ensure that registers of infrastructure and of rolling stock are published and updated annually. Those registers shall indicate the main feature of each subsystem or part subsystem involved and their correlation with the features laid down by the applicable TSIs. To that end, each TSI shall indicate precisely which information must be included in the registers of infrastructure and of rolling stock.’

Due to the annual update and publication of these registers they are not utilisable for the subsystem Telematic Applications for Freight. Therefore this TSI has nothing to indicate in these registers.

5.INTEROPERABILITY CONSTITUENTS

5.1.Definition

According to Article 2(d) of Directive 2001/16/EC, interoperability constituents are ‘any elementary component, group of components, subassembly or complete assembly of equipment incorporated or intended to be incorporated into a subsystem upon which the interoperability of the trans-European conventional rail system depends directly or indirectly. The concept of a constituent covers both tangible objects and intangible objects such as software’.

5.2.List of constituents

The interoperability constituents are covered by the relevant provisions of Directive 2001/16/EC.

There are no interoperability constituents determined as far as the subsystem Telematic Applications for Freight is concerned.

For the fulfilment of the requirements of this TSI only standard IT equipment is needed, without any specific aspects for interoperability in the railway environment. This is valid for hardware components and for the standard software used like operating system and databases. The application software is individual on each user's side and can be adapted and improved according the individual actual functionality and needs. The proposed ‘application integration architecture’ assumes that applications might not have the same internal information model. Application integration is defined as the process of making independently designed application systems work together.

5.3.‘Constituents’ performances and specifications

See Chapter 5.2, not relevant for the TSI telematic applications for freight.

6.ASSESSMENT OF CONFORMITY AND/OR SUITABILITY FOR USE OF THE CONSTITUENTS AND VERIFICATION OF THE SUBSYSTEM

6.1.Interoperability constituents

6.1.1.Assessment procedures

The assessment procedure for conformity or suitability for use of interoperability constituents must be based on European specifications or specifications approved in accordance with Directive 2001/16/EC.

In the case of suitability for use, these specifications will indicate all the parameters to be measured, monitored or observed, and will describe the related testing methods and measuring procedures, whether in a test-bench simulation or tests in a real railway environment.

Procedures for assessing conformity and/or suitability for use:

List of specifications, description of the testing methods:

Not relevant for the TSI telematic applications for freight

6.1.2.Module

At the request of the manufacturer or his representative established in the Community, the procedure is carried out by a notified body in accordance with the provisions of the pertinent modules of Council Decision 93/465/EEC as set out, amended and supplemented in the Annex to this TSI.

The modules should be combined and used selectively according to the particular constituent.

Not relevant for the TSI telematic applications for freight.

6.2.Subsystem Telematic Applications for Freight

At the request of the awarding authority or its representative established in the Community, the notified body carries out EC verification in accordance with Annex VI to Directive 2001/16/EC.

According to Annex II to Directive 2001/16/EC, the subsystems are broken down into structural and operational areas.

The conformity assessment is obligatory for TSIs in the structural area. The subsystem Telematic Applications for Freight belongs to the operational area and this TSI does not determine any modules for conformity assessment.

However the central repository and a common interface at each actor's node are the backbone of the application integration. The exchange information model is held in the centralised application integration repository, which holds the interface metadata in one physical location. The metadata contains information about the communication content (what is in the data being sent), the touch point identities of the senders and receivers, and the interaction process mechanics application-level business protocols.

The following points are highlighted:

The central repository contains the directory (phonebook) of all participating actors for the exchange of messages. This directory must represent the actual status at all times. Wrong entries become obvious immediately. No assessment procedure needed.
The central repository also contains the certification authority (Open CA PKI). This is mainly an administration act, which is physically implemented. Wrong entries become obvious immediately. No assessment procedure needed.
The central repository contains the message metadata (according to Annex A, Index 1) as the basis for message exchange in a heterogeneous information environment. The metadata must be administrated and updated in the central repository. Any incompatibility in the message structure or content of the messages for sending or receiving data will be recognised immediately and the transfer will be refused. No assessment procedure needed.
The common interface at each actor's node contains mainly the local ‘mirror’ of the central repository for shortening the response time and reducing the load on the repository. It must be ensured, that the data versions in the central repository and in the common interface are always the same. Therefore the data update must be done on the central level and new versions must be downloaded from there. No assessment procedure needed.

7.IMPLEMENTATION

7.1.Modalities of application of this TSI

7.1.1.Introduction

This TSI is oriented to provide information support to the rail freight business process that can lead to a major enhancement of the quality of transportation services. As such its application is independent from the notions of new/upgrade or legacy infrastructure or rolling stock assets as it is usual in other TSI called for by Directive 2001/16/EC.

Due to its pervasive nature the impact of this TSI will be profound on the business and operational processes of the whole of the European rail industry. Moreover, the continuous growth of international freight transport demands a European-wide information management perspective. These facts compound to call for the set-up of a coherent trans-European implementation plan for this TSI. This plan should provide both a vision of what is to be achieved when implementing the TSI and the way and timing to migrate from the present framework of fragmented information systems towards a comprehensive European-wide information highway that can provide value-added to all rail transport stakeholders — infrastructure managers, railway undertakings, freight forwarders and ultimately the client alike.

Set against this background the concept of a Strategic European Deployment Plan (SEDP) is mandated. The SEDP defines the target system that is to be achieved in order to implement this TSI together with its underpinning roll-out plan as outlined in the following paragraph.

7.1.2.Strategic European Deployment Plan (SEDP)

7.1.2.1.Objectives of the SEDP

The purpose of the Strategic European Deployment Plan (SEDP) is threefold:

to provide a vision for the implementation of the TAF TSI within the European rail industry;

to qualify such a vision from a technical and economic feasibility perspective;

to establish a roadmap of the activities deemed necessary in order to realise such a vision.

In addition to provide a roadmap for the implementation of the TAF TSI ensuring visibility of the whole implementation process, the SEDP should bestow appropriate yardsticks for the monitoring of its progress by the different stakeholders — namely infrastructure managers, railway undertakings, freight forwarders and ultimately the client — in a way that can guarantee the defence of their best interests. This regards notably the required investments to be mobilised by the infrastructure managers and railway undertakings in the potential upgrading and integration of their legacy IT systems and the capability of the TAF TSI-based systems in effectively responding to the ever evolving needs of information from freight forwarders and clients alike.

Set against this background, the SEDP should ultimately constitute an instrument enabling to focus the whole of the European railway industry on a pan-European information system development target, whilst allowing for the promotion of synergies, avoidance of fragmentation and the concentration of limited resources on those priority issues better responding to the overriding transportation service quality goals.

7.1.2.2.The SEDP requirements

The elaboration of such a plan will require a systematic analysis of the relevant technical, operational, economic and institutional issues that underpin the implementation process of the TAF TSI. This includes in particular:

the inventory of the relevant legacy IT applications that could constitute the foundation on which to build a pan-European system capable of delivering the TAF TSI requirements (hereafter called the TAF system);

the definition of the functional and associated data and performance requirements necessary to deliver the TAF TSI;

the outline of the TAF system architecture. This shall be based on the analysis of the system configurations capable of potentially integrating the legacy IT facilities while delivering the required functionality and performance — e.g. centralised or distributed client-server architectures, agent-based architectures;

the establishment of the technical and interface requirements for the TAF system and its potential sub/client systems;

the elaboration of an overall TAF system development plan from concept-to-delivery. This should provide guidelines on the process and the planning for the potential integration of legacy facilities as well as a risk assessment of the crucial phases of such a plan. Moreover, it should account for the ongoing and planned evolution of legacy facilities;

the identification of the appropriate governance structures underpinning the development of the TAF system as well as its operation throughout its lifetime;

an assessment of the total life cycle costs (LCC) associated with the roll-out and operation of the TAF system together with a subsequent investment plan.

Rather than following a sequential path this analysis should evolve through an iterative basis aimed at identifying the optimum system deployment strategy. Such study cycle should conduce ultimately to the following specific outcome:

a full set of functional, performance, system and technical specifications for the procurement of the TAF system,
a rollout programme from concept-to-delivery. This shall include the detailed planning of all those project phases and major individual activities that concur to the achievement of the end goals,
a definition of the governance structure, methods and procedures ((7)) underpinning system development, validation and operation,
an investment plan and a subsequent financial engineering approach enabling its realisation.

7.1.3.Modalities for implementation

The modalities for application of this TSI are subject to the requirements of the Strategic European Deployment Plan (SEDP) as outlined previously.

For the purpose of the elaboration of the SEDP the following requirements do apply:

Railway Undertakings and Infrastructure Managers shall contribute by providing functional and technical information about the existing individual telematics applications for freight(8);
The representative bodies from the railway sector acting on a European level as defined in Article 3(2) of Regulation (EC) No 881/2004 shall establish a Strategic European Deployment Plan as outlined in the previous paragraph. They shall forward this strategic plan to the Member States and the Commission not later than one year after the date of publication of this Regulation. If after this period of time no significant progress is observed the task will be embraced by the European Commission to subsequently propose draft legislation for the implementation of this TSI.
Once the strategic plan is completed, all activities related to the implementation of the subsystem Telematic Applications for Freight have to be justified against this deployment plan. Any proposed non-adherence by a RU or IM should be justified in the implementation dossier submitted to the Member State, to the European Railway Agency and to the EC.

7.2.Migration strategy

Migration strategies have to be devised in order to cater for the transition period between the current framework of differentiated information systems and the fulfilment of this TSI as commanded by the SEDP.

For this purpose the information handling concepts embodied in this TSI where developed in order to facilitate such a migration. They do allow for an incremental build-up of the target TAF TSI pan-European system, notably through facilities such as peer-to-peer communication based e.g. on the concept of aggregate data repositories (namely including message metadata, data directory and certification authority).

An illustrative example how such information exchange between a RU and IM could work in practice is given below. The example shows only the logical inter-system communication dependencies structured in stepwise manner without accounting for any individual migration needs that might be required by the individual systems. These latter needs should be duly considered when drawing up the SEDP.

Step 1: The general architecture, as described in Chapter 4.2.14.1 (General architecture), embodies the concept of a ‘central repository’ operated by a neutral and independent entity. At the site of each participant in the communication network, an interface layer, which may include a message broker, is specified for interoperability, which can be built centrally or individually. These parts are in respect of ‘networking and communication’, the only operational aspects required for interoperability. They are also the basic preconditions for the European-wide data exchange. Therefore they must be realised and installed before any other function can come into operation.

After this step already the electronic transmission of documents (Chapter 4.2.13:) may be realised independent from the logical sequence of the other steps.

Available features after this step for
IM	RU
The basis for the information exchange is given. Advantage: Electronic transmission of documents in the final environment is possible. Tests of the various further steps can be made in real environment.

Available features after this step for

The basis for the information exchange is given.

Advantage:

Electronic transmission of documents in the final environment is possible.
Tests of the various further steps can be made in real environment.

Step 2: At the same time or shortly after step 1, the Rolling Stock Reference Databases and the Wagon and Intermodal Unit Operational Database (Chapter 4.2.11.3: The Rolling Stock Reference Databases and Chapter 4.2.12.2: Other databases) must be available. If not all data are already in the databases, it must be at least possible to put manually into the Wagon and Intermodal Unit Operational Database — for each wagon in a running train — the data needed for rail transport as listed in Annex A, Index 2).

Available features after this step for
IM	RU
The basic information in the Wagon and Intermodal Unit Operational Database and the Rolling Stock Reference Databases are accessible. A manual update of the relevant data is possible. Advantage: The IT support for a path request and for the train composition is given. An easy access to the rolling stock data for third parties e.g. fleet managers can be realised.

An easy access to the rolling stock data for third parties e.g. fleet managers can be realised.

Step 3: For outside access to the various databases the common interface must be realised and implemented in parallel or shortly after step 2.

Available features after this step for
IM	RU
A database for the storage of path/train information is prepared. The data input can start manually. The on-line connection to the existing IM systems for the automatic input and update is available. Advantage: Data of incoming messages can be stored as for the final version.	The database(s) for the movement data of wagons/intermodal units and for the load (weight, dangerous goods) is prepared, together with the reference files needed. From now on the relevant data from the delivered consignment notes (wagon order) and/or of the existing train composition can be filled in manually or already automatically via RU internal connection to the existing systems for recording the consignment notes and for recording the train composition. The check of the wagon data with the Rolling Stock Reference Databases is possible as well as the assessment of the train data with the infrastructure data. Advantage: Support for creating the train composition. Data of incoming messages can be stored as for the final version.

The check of the wagon data with the Rolling Stock Reference Databases is possible as well as the assessment of the train data with the infrastructure data.

Advantage:

Support for creating the train composition.
Data of incoming messages can be stored as for the final version.

For the next steps it is important to mention, that the proposed architecture allows for a smooth coming into operation of the various functions to fulfil the requirement of the subsystem Telematic Applications for Freight. Based on the central repository (message metadata, directory and certification authority), it is possible to enable the data exchange between two partners individually depending on message type.

Step 4: The Path Request messages can be implemented independent from the next steps, but for step 6 it is necessary that the path is already named by a path number.

7.3.Management of change

7.3.1.Introduction

Change is a facet inherent to any kind of computer-based systems used in real-world environments. It is prompted by the emergence of new requirements or by changes to existing requirements either due to errors reported in operation or the need of improvements in performance or other non-functional characteristics.

But change has to be managed as it is underpinned by continuity of service considerations and by backward compatibility objectives so as to provoke minimal time and cost overheads to the operation of already deployed IT equipment providing TAF functionality (i.e. legacy IT facilities). It is therefore crucial to define a clear strategy of how to implement and manage change to legacy IT equipment to avoid disruption to railway operations without undermining the underlying objectives of guaranteeing continuity of service and interoperability. Two main issues underpin the definition of such a strategy:

the establishment of a configuration management framework defining the standards and procedures for managing system evolution. This should include how to record and process proposed system changes, how to relate these changes to system components and how to track system releases,
a policy for release of system baselines.

7.3.2.Baselining

System stability is essential so that actual implementation and deployment can be realistic. This need for stability is akin to all parties:

the infrastructure managers and the railway operators that will have to handle various versions of systems providing TAF functionality,
the industry that needs time to specify, develop and prove continued interoperability.

A baseline in essence embodies the concept of a stable kernel in terms of system functionality, performance and other non-functional characteristics (e.g. RAM)(9). However, past experience with this type of systems has shown that a number of version releases(10) are needed to achieve a stable and implementation-suitable baseline. This can be illustrated as a cascade process as follows:

Through its feedback loops, such a process is highly intertwined. This precludes putting several of those processes in parallel, an approach that would lead to unstable, confusing and operationally hampering situations. Baselines have then to be processed in a series rather than in a parallel manner as illustrated below:

7.3.3.Baseline release

Based on current experience the timing between different baselines can be estimated to be circa four to five years.

A new baseline should in principle be linked with significant modifications of the system functionality or system performance. This could include aspects such as:

the incorporation of set of today's national functions, where these can be generalized, within the interoperable kernel,
other future value-added services.

Each baseline should also embrace the functionality of the previous baseline. Debugging versions to repair system faults or security shortcomings should be handled as a version release of a particular baseline. Unless prevented by security implications such version releases within the same baseline are to be backward compatible.

The added functionality that might be embodied in different baselines necessarily implies that different baselines are not backward compatible. However, in order to facilitate migration and in the extent possible from a technical view point, different baselines should encompass a common core of functionality for which backward compatibility should be ensured. Such a common core should provide a minimum kernel to enable interoperable data services under acceptable performance.

7.3.4.Deployment of new baselines

Infrastructure managers and railway operators will never be in a position to switch from one baseline to the next over night. Henceforth, each baseline has to developed hand-in-hand with an appropriate migration strategy. This is to address problems such as co-existence of TAF facilities compliant with different versions of the TAF specifications, preferred paths of migration (namely trackside priority, rolling-stock priority or simultaneous) as well as the indicative timeframes and the priorities for the migration.

7.3.5.Change management process — the requirements

As mentioned earlier, change is a fact of life for large software based systems. Henceforth, change management procedures should be designed to ensure that the costs and benefits of change are properly analysed and that changes are implemented in a controlled way. This requires the defined change management process and associated tools to ensure that changes are recorded and applied to the specifications in a cost-effective manner. Whatever the specific details of such a process might eventually be, the latter should be broadly mapped on a structured approach as follows:

A configuration management plan embodying the set of standards and procedures for change management should underpin the whole of the change management process as described above. The generic requirements for such a plan are described in paragraph 7.3.6. The implementation strategy for the approved changes should be formalised (on the basis of due process and due documentation) into a change management plan that includes notably:

the identification of the technical constraints underpinning the change,
a statement of who takes responsibility for the change implementation procedures,
the validation procedure for the changes to be implemented,
the policy for change management, release, migration and roll-out.

An important part of the change management process is the definition of the responsibilities for the delivery of the specifications and for both its quality assurance and configuration management. It is planned that most of these tasks will revert to or will be supervised by the European Railway Agency (established by Regulation (EC) No 881/2004) when this will begin operation. The change management process should be formalised within the set of documentation referred to in Annex A.

Finally, it is essential that the Change Control Board (CCB), which eventually will act as overall system authority, is composed of a representative cross-section of the all interested parties — namely infrastructure managers, railway undertakings, supply industry, notified bodies and regulatory authorities alike. Such affiliation of the parties should ensure a system perspective on the changes that are to be made and a global assessment of their implications. The CCB ultimately will be put under the aegis of the European Railway Agency.

7.3.6.Configuration management plan — the requirements

The configuration management plan should describe the set of standards and procedures for change management encompassing notably:

the definition of what entities are to be managed and a formal scheme for identifying these entities,
a statement of who takes responsibility for the configuration management procedures and for submitting controlled entities to the configuration management decision structure,
the configuration management policies that are to be used for change control and version management,
a description of the records of the configuration management process which should be maintained,
a description of the tools to be used for configuration management and the process to be applied when using these tools,
a definition of the configuration database which will be used to record configuration information.

The specific details of the configuration management processes are to be formalised through specifications to be incorporated in the list of specifications included under Annex A to this TSI.

7.4.Specific cases

7.4.1.Introduction

The following special provisions are permitted in the specific cases below.

These specific cases belong to two categories: the provisions apply either permanently (case P), or temporarily (case T). In temporary cases it is recommended that the Member States concerned should conform with the relevant subsystem either by 2010 (case T1), an objective set out in Decision No 1692/96/EC of the European Parliament and of the Council of 23 July 1996 on Community guidelines for the development of the trans-European transport network(11), or by 2020 (case T2). ‘T open’ is defined as an undetermined period, which will be fixed in a future revision of this TSI.

7.4.2.List of specific cases

7.4.2.1.Specific case for EU member states with border to third countries

On the territories of EU Member States having a border with third countries, the requirements of this TSI are not obligatory to transports directly arriving from or going to these third countries (case T open).

However if the transport journey will be extended to another EU Member State, then the requirements of this TSI must be applied in full, provided that there is not a bilateral or multilateral agreement between the States concerned or between RUs or IMs acting in the territory of those Member States

7.4.2.2.Specific case for Greece

For a transport journey operated on lines with 1 000 mm track gauge, national rules shall apply.
