Introduction
This Technical Specification is based on 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, the requirements laid down in the
different parts of the EN 45545 will take into account the current operating conditions for European public
rail transport.
1 Scope
This Technical Specification specifies the fire safety requirements for electrical equipment on railway
vehicles, including that of trolley buses, track guided buses and magnetic levitation vehicles.
The measures and requirements, specified in this Technical Specification meet the objective of protecting
passengers and staff in railway vehicles in the event of a fire on board by:
minimising the risk of starting a fire both during operation and as a result of technical defect and/or
malfunction of the electrical equipment;
ensuring that electrical emergency equipment continues to be available until evacuation is complete.
It is not within the scope of this Technical Specification to describe measures which ensure the
preservation of the electrical equipment in the event of a fire on board.
