This European Standard has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association. This European Standard supports essential requirements of EU Directives 96/48/EC (HSR) and 2001/16/EC (CONRAIL) and 2008/57/EC (RAIL). Specifically, this standard is intended to define the requirements for rolling stock running capability in CEN/TS 45545 and in the TSI "Safety in railway tunnels" (TSI SRT). It is also intended to define specific technical measures, compliance with which will allow a "Presumption of Conformity with the TSI SRT" to be made by the notified body assessing the rolling stock. This standard defines fire conditions for which it is reasonable to expect trains to continue to run in a controlled manner, and defines requirements ensuring this "running capability". This standard identifies the fire conditions for which it is not necessary to define running capability requirements as there is no significant potential for serious injury or threat to life. This standard considers the requirement to "improve the probability that a passenger train with a fire on board will continue to operate..." in a "reasonably practicable" context. It is understood that "train" includes all vehicles such as locomotives and power cars which are associated with the passenger vehicles. Requirements for running capability cannot be defined without knowledge of other fire characteristics of the train, specifically its reaction to fire and fire resistance specification. The assumption is made that the fire standard applied is CEN/TS 45545 series or any standard for which technical equivalence can be demonstrated. The standard defines requirements based on a philosophy which recognizes that stopping a train is not itself a life-threatening event. It is therefore not required to have running capability for all fires; only those fires which may cause serious injury and/or develop to threaten life. The responsible committee is Subcommittee UK 351.1 "Fahrzeuge" ("Rolling stock") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
