The CCS TSI 2023/1695 gives the Infrastructure Managers (IMs) the possibility to publish a catalogue of ETCS/Radio System Compatibility Checks (ESC/RSC) for their network. Applicants for vehicle authorisation have to demonstrate compatibility to the IMs’ ETCS network by executing successfully the ESC (and/or RSC). ERA launched a questionnaire to capture feedback on ESC from the sector. In preparation to the substantiated report, ERA wants to further collect input from the sector. This workshop will be used as a sharing experience platform where Infrastructure Managers, Railway Undertakings, Manufacturers, Notification Bodies, National Safety Authorities and Laboratories can exchange experiences and make proposals aiming at reducing or even removing these checks.
