THE COMMISSION OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Community,
Having regard to Council Directive 96/48/EC of 23 July 1996 on the interoperability of the trans-European high-speed rail system , and in particular Article 6(2) thereof,
OJ L 235, 17.9.1996, p. 6 .
Having regard to Directive 2001/16/EC of 19 March 2001 on the interoperability of the trans-European conventional rail system , and in particular Article 6(1) thereof,
OJ L 110, 20.4.2001, p. 1 .
Whereas:
(1) This Decision refers to infrastructure and rolling stock equipment which are subject to Directives 96/48/EC and Directives 2001/16/EC and are to be placed in service after the date on which this Decision takes effect.
(2) The first objective of this Decision is to guide the technical choices made by authorities responsible for planning, constructing, renewing, upgrading and operating the abovementioned infrastructure and rolling stock.
(3) The second objective of this Decision is to update the Annex A of the Commission Decision 2002/731/EC of 30 May 2002 concerning the technical specification for interoperability relating to the control-command and signalling subsystem of the trans-European high-speed rail system referred to in Article 6(1) of Council Directive 96/49/EC .
OJ L 245, 12.9.2002, p. 37 .
(4) The third objective of this Decision is to establish a definitive reference of the set of specifications that are to be considered in the context of the control-command and signalling subsystem of the trans-European conventional rail system referred to in Article 6(1) of Directive 2001/16/EC. It does not preclude the need to validate and, if necessary, further amend, update or modify these parameters in the corresponding TSI (TSI CCS-CR), which shall be adopted in accordance with Directive 2001/16/EC. These parameters may also be updated as part of the review of the TSIs provided for in this Directive and considering the opinion expressed in the change control management procedure as provided for in the TSI CCS-HS.
(5) In accordance with Article 2(c) of Directive 96/48/EC, the trans-European high-speed rail system is subdivided into structural or functional subsystems. Each of the subsystems is to be covered by a technical specification for interoperability (TSI).
(6) Decision 2002/731/EC has set up the TSI relating to the control-command and signalling subsystem of the trans-European high speed rail system (TSI CCS-HS).
(7) The Committee set up under Article 21 of Directive 96/48/EC (hereafter the Committee) has appointed the European Association for Railway Interoperability (hereafter the AEIF) as the joint representative body.
(8) The joint representative body shall be responsible for preparing the review and updating of TSIs and making recommendations to the Committee referred to in Article 21 in order to take account of developments in technology or social requirements.
(9) The AEIF has been given a mandate to review the TSI CCS-HS.
(10) As a result of technological evolution as well as of the feedback of the first set of field applications, a major update of the set of specifications included in Annex A of the above mentioned TSI CCS-HS is deemed required. The AEIF has drawn up the draft of the revised Annex A to the TSI CCS-HS.
(11) The draft revised Annex A has been examined by the representatives of the Member States, in the framework of the Committee.
(12) In accordance with Article 2(c) of Directive 2001/16/EC, the trans-European conventional rail system is subdivided into structural or functional subsystems. Each of the subsystems is to be covered by a technical specification for interoperability (TSI).
(13) As a first step, draft TSIs have to be drawn up by the joint representative body under a mandate from the Commission in accordance with the procedure set out in Article 21(2) to the Directive.
(14) The Committee set up under Article 21 of Directive 2001/16/EC (hereafter the Committee) has appointed the European Association for Railway Interoperability (hereafter the AEIF) as the joint representative body.
(15) The AEIF has been given a mandate to draw up a draft TSI for the control-command and signalling subsystem of the trans-European conventional rail system (TSI CCS-CR).
(16) However, in accordance with Article 6(4) of Directive 2001/16/EC, the first stage in developing the abovementioned TSI is to establish the characteristics of its basic parameters.
(17) In accordance with the abovementioned mandate the AEIF has already drafted a complete TSI for the command-control and signalling subsystem of the trans-European conventional rail system (TSI CCS-CR). This TSI will be adopted once the cost-benefit analysis foreseen by Directive 2001/16/EC are developed and after consultation of users organisations and social partners.
(18) The multiplication of ERTMS-related projects for conventional applications both within the European Union and in the accessing countries does press for a reference for conventional rail to emerge. Most of these projects evolve nowadays based on a loose compliance with the current TSI CCS-HS, a situation that could potentially lead to yet another non-interoperable legacy at European level then rooted on different national flavours of ERTMS.
(19) The extension of the high-speed parameters to conventional rail is clearly justified by both market and operational reasons. They range from the scale-effects associated to a uniqueness of solutions between high-speed and conventional rail, to the fulfilment of the operational needs of high-speed trains when they are bound to use the conventional network.
(20) A unique solution for both high-speed and conventional rail is a pivotal concept underpinning ERTMS that has commanded a strong support within the railway sector at large — both by the supply industry and by the railway companies alike.
(21) The revised reference basic parameters for the TSI CCS-HS should therefore be also adopted as the reference basic parameters for the Class A system of the TSI CCS-CR.
(22) The measures provided for in this Decision are in accordance with the opinion of the Committee set up by Directive 96/48/EC,
HAS ADOPTED THIS DECISION:

Article 1 The Annex A to the TSI attached to Decision 2002/731/EC setting up the TSI relating to the control-command and signalling subsystem of the trans-European high-speed rail system is replaced by the table mentioned in the Annex to this Decision.

Article 3 This Decision is addressed to the Member States.

ANNEX ERTMS CHARACTERISTICS

1. DESCRIPTION OF THE PARAMETER
The unified control/command and signalling subsystem (ERTMS — European rail traffic management system) comprise two elements:
the control/command and signalling element (ERTMS/ETCS — European rail traffic management system/European train control system) covers both the onboard subsystems and track-side subsystems,
the radio and telecommunication element (ERTMS/GSM-R — GSM for railways) is based on the standards applied to the public GSM network and also covers both track-side and onboard equipment. GSM-R is based on ETSI standard GSM phase 2+, including GPRS (global packet radio services), extended to railway-specific applications.

2. CHARACTERISTICS TO BE RESPECTED

2.1. ERTMS/ETCS:
The basis for the control-command and signalling subsystem shall be the set of specifications listed in the following table. If deemed necessary, these specifications can be revised and extended in accordance with the TSI revision procedure of Directives 96/48/EC and 2001/16/EC. Such a revision will consider the opinion expressed in the ERTMS Change Control Management procedure, taking into account the fact that a consolidation phase is necessary for the ERTMS specifications, based on the trial sites and the first implementations

The cab-signals define the minimum range of parameters made available in the cab that together satisfy all the circumstances that could be found upon the railways of the European high-speed network and that therefore make a system common for the whole network feasible. Such parameters would be permitted speed, target speed, target distance, that are the basis of cab-signalling and ATP.

10	r4.1.1	Vigilance (dead man's) system requirements.	The definition of a vigilance function so that the train can operate acceptably on the European networks. Vigilance ensures that the driver is sufficiently alert (and by implication sufficiently alert to be aware of the signalling). If a timer is used, the timer can be reset by other driver actions on the train controls, traction controller, brakes, cab warning acknowledgement. It can be associated with a need to hold a lever in a given position (dead man function). The functionality required of the vigilance can be modified by the status of ATP and any cab warning system. Vigilance, ATP and cab warning systems are safety related systems in the sense that they support the driver and provide protection to the train in the event of human inadequacy. The level of safety is determined by all these systems, and they are inter-dependent in the sense that the presence or absence of one can affect the functionality of the others. The management of the safety issues is facilitated by considering these systems to be in the scope of control-command. UIC 641 is to be the basis for European Specification.	Reserved
