Overview
EN 45545-6:2024+A1:2026 is an essential European Standard developed by CEN covering fire protection on railway vehicles, specifically focusing on fire control and management systems. This part of the EN 45545 series outlines the requirements for the design, implementation, and operation of fire detection, alarm, response, and fire-fighting systems on rolling stock. Its primary objective is to enhance fire safety measures for passengers and staff by ensuring timely detection and effective management of fire events inside railway vehicles.
The standard aligns with EU Directive (EU) 2016/797, concerning the interoperability of the rail system, and is intended for adoption across the European Union, supporting harmonized fire safety requirements for railway applications.
Key Topics
-
Fire Detection and Alarm Systems
Specification of requirements for both automatic and manually initiated fire detection systems, ensuring early identification of fire incidents in critical areas such as passenger compartments, technical cabinets, catering areas, and more.
-
Emergency Information and Communication
Guidelines for alarm notification, including audible and visual alarms for local and remote alerts, enabling effective communication between passengers, onboard staff, drivers, and control centers in the event of a fire.
-
Equipment Shutdown and Energy Isolation
Procedures for the selective shut down of electrical and mechanical systems likely to contribute to fire spread, taking into account primary (targeted components) and secondary (broader area-specific needs) requirements.
-
Automatic and Manual Fire Response
Requirements for automatic and manual activation of fire fighting equipment, including the deployment of fixed systems in high-risk areas and portable extinguishing means accessible throughout the train.
-
Passenger Alarm Systems
Specifications for the design and implementation of passenger-initiated alarm systems as per EN 16334-1, enabling effective intervention through staff alerts, braking systems, and two-way voice communication.
-
Functionality Under Fire Conditions
Assurance that fire management systems remain operational for the required duration during an incident, maintaining their essential functions and integrity throughout the fire emergency.
Applications
EN 45545-6:2024+A1:2026 applies to a wide range of railway rolling stock as defined in EN 45545-1:2013, including:
-
Passenger trains
Ensuring safety for high-speed trains, metros, commuter trains, and regional trains by providing comprehensive fire detection and suppression systems.
-
Specialized railway vehicles
Covering vehicles with technical cabinets, cooking areas, batteries, or combustion engines, which require targeted fire protection strategies.
-
Infrastructure for staff and technical equipment
Protecting staff areas, control cabs, and technical equipment compartments to minimize risks and support continuity of essential train operations during fire events.
Railway manufacturers, system integrators, operators, and maintenance providers benefit from implementing this standard, enabling compliance with European safety requirements and supporting safe, reliable rail transport for both passengers and staff.
