Requirements Capture Process in the Vehicle Authorisation Procedure

Vehicle authorisation procedure required by Directive (EU) 2016/797 on the interoperability of the rail system within the European Union is in line with the Fourth Railway Package and the adopted one-stop shop approach. The main legal texts on the procedure are included in the Regulation (EU) 2018/545 and its article 13 relates to requirements capture process of all applicable requirements. In the paper we analyse several topics, identify issues and doubts, provide clarifications, and propose two models of the requirements capture process in the context of the vehicle authorisation procedure.
