SIST EN 45545-5:2013/kFprA1:2015

Railway applications - Fire safety on railway vehicles - Part XX: Fire safety requirements for electrical equipment including that of trolley buses, track guided buses and magnetic leviation vehicles

This part of EN 45545 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 functional until evacuation is complete (see EN 45545-6).

Overview

EN 45545-5:2013/FprA1 is a CEN draft amendment to the European standard EN 45545-5 that defines fire safety requirements for electrical equipment on railway vehicles, including trolley buses, track-guided buses and magnetic levitation vehicles. The standard aims to protect passengers and staff by reducing the risk of fire originating from electrical equipment and by ensuring that emergency electrical systems remain functional until evacuation is complete (see EN 45545-6).

Key topics and technical requirements

• Scope: Fire safety for onboard electrical equipment across a range of rail-based and guided vehicles (including trolley buses and maglev).
• Objective: Lower ignition risk from electrical faults and ensure emergency equipment reliability during evacuation.
• Amendment highlights (FprA1):
  • Modification to Clause 2 (Normative references): adds EN 50547 (Batteries for auxiliary power supply systems).
  • Revision of Clause 5.6 (Batteries and battery supply circuits) with specific requirements:
    • Battery venting: gases must be vented to the vehicle exterior and not into passenger or staff areas.
    • Battery conformity: batteries for auxiliary power systems shall comply with EN 50547.
    • Cable insulation: cables between batteries and protective devices must be insulated against short circuits via:
      • supplementary insulation per EN 61140, or
      • internal battery-box insulation with electrolyte-resistant varnish.
    • Protective devices: where neither battery pole is bonded to the vehicle body, protective devices must be fitted to both poles. For interconnections between separate battery enclosures, protective devices are required only on external poles, not on interconnection cables.
• Safety linkage: references EN 45545-6 for emergency system performance until evacuation completion.

Applications

• Design, manufacture and installation of onboard electrical systems for trains, trams, trolley buses, guided buses and maglev vehicles.
• Specification and procurement of batteries and auxiliary power systems for rail vehicles.
• Risk assessments and fire-hazard mitigation during vehicle design and retrofits.
• Maintenance procedures and depot installations where battery venting and electrical protection are relevant.

Who should use this standard

• Rolling-stock designers and vehicle OEMs
• Electrical system and battery suppliers
• Safety and compliance engineers
• Certification bodies and regulatory authorities
• Maintenance planners and depot engineers

Related standards

• EN 45545-6 - fire safety requirements for electrical emergency equipment (performance during evacuation)
• EN 50547 - batteries for auxiliary power supply systems (new normative reference)
• EN 61140 - protection against electric shock (insulation guidance)

This standard is issued by CEN and supports harmonized fire-protection requirements across European railway applications. Keywords: EN 45545-5:2013/FprA1, railway fire protection, electrical equipment, batteries, auxiliary power, trolley bus, maglev, EN 50547, EN 61140.
