Introduction
EN 45545-6 has been developed from existing fire safety regulations for railway vehicles from the
International Union of Railways (UIC) and different European countries.
In using the operation and design categories defined in EN 45545-1:2013, the requirements laid down in
this part take into account the current operating conditions for European public rail transport.

1 Scope
This document specifies requirements for fire detection, alarm systems, equipment shutdown,
information and communication systems, emergency lighting, emergency brake systems and fire fighting
systems to cover the objectives defined in EN 45545-1:2013.
The measures and requirements specified in this document aim to protect passengers and staff in railway
vehicles in the event of a fire on board by alerting staff and passengers to a fire, delaying the fire
development and controlling the movement of smoke.
It is not within the scope of this document to describe measures that ensure the preservation of the
railway vehicles in the event of a fire.
This part is valid for railway vehicles defined in EN 45545-1:2013.
