Requests for infrastructure capacity may be made by applicants. In order to use such infrastructure capacity, applicants shall appoint a railway undertaking to conclude an agreement with the infrastructure manager in accordance with Article 28. This is without prejudice to the right of applicants to conclude agreements with infrastructure managers under Article 44(1).

The infrastructure manager may set requirements with regard to applicants to ensure that its legitimate expectations about future revenues and utilisation of the infrastructure are safeguarded. Such requirements shall be appropriate, transparent and non-discriminatory. They shall be specified in the network statement as referred to in point 3(b) of Annex IV. They may only include the provision of a financial guarantee that shall not exceed an appropriate level which shall be proportional to the contemplated level of activity of the applicant, and assurance of the capability to prepare compliant bids for infrastructure capacity.

Before 16 June 2015, the Commission shall adopt implementing measures setting out the details of the criteria to be followed for the application of paragraph 2. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 62(3).
