This Part of EN45545 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 European Standard meet the objective of protecting passengers and staff in railway vehicles in the event of a fire on board by: lowering 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 functional until evacuation is complete (see EN45545‑6 ).
