This document does not cover urban rail rolling stock.
NOTE 1 EN 17355 covers communication device requirements for urban rail rolling stock.
This document specifies:
- the functional requirements for a call for aid system and communication device system;
- the dynamic analysis of the call for aid system.
NOTE 2 "Dynamic analysis" is understood here as a sequence of actions.
NOTE 3 In a formation of vehicles where one complies with this document with one that does not, it is possible that the call for aid system is not fully functional.
NOTE 4 The call for aid system function is separate from the Passenger Alarm System (PAS) function, which is provided to deal with emergency situations. The PAS is described in EN 16334-1:2014+A1:2022.
