Introduction
EN 45545-4 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 specified 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 fire safety requirements for railway vehicle design to cover the objectives
specified 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 minimizing the risk of a fire starting, delaying the fire
development and controlling the spread of fire products through the railway vehicle, thus aiding
evacuation.
It is not within the scope of this document to describe measures which ensure the preservation of the
railway vehicles in the event of a fire.

4 Fire protection measures
4.1 General
In consideration of the wide range of possible interior layouts for rail vehicles it is only possible to specify
a limited number of normative requirements to control the risks of fires starting accidentally or
deliberately and to then control the risks of such fires spreading. Informative guidance is therefore set
out in Annex A to provide accepted good practice and design aspects to be considered.
NOTE Requirements for smoke containment are covered in EN 45545-6.
4.2 Minimizing the risk of a fire starting
4.2.1 General preventive measures
Access shall be denied to all areas not intended for passenger use. These shall include, where applicable,
but are not limited to:
— drivers’ cabs;
— staff areas, for example staff offices, compartments, catering and cooking areas;
— luggage compartments;
— areas behind ceiling hatches or access panels;
— the interior of technical cabinets (including engine compartments);
— the interior of underfloor equipment cases.
Unauthorised areas shall be locked or oth
