EN 45545-2
The Reference Standard for Fire Safety in the Railway Industry
ECOFIT ventilation solutions can be adapted for railway applications to comply with EN 45545-2, the European reference standard for fire protection in railway vehicles.
Today, this standard is essential for manufacturers, system integrators, and railway operators. It defines the fire performance requirements for materials and components used in rolling stock, with the primary objective of protecting passengers and crew in the event of a fire.
EN 45545-2 applies to a wide range of railway vehicles, including regional trains, high-speed trains, metro systems, trams, and overnight trains. It establishes strict requirements for the fire behavior of materials to limit flame spread, smoke generation, and the release of toxic gases.
What Is the Purpose of EN 45545-2?
The objective of EN 45545-2 is to reduce fire-related risks on board railway vehicles. In the event of a fire, the ability of passengers to evacuate safely depends largely on the fire performance of materials used in interior fittings, electrical equipment, and wiring systems.
To address these risks, the standard evaluates several key criteria:
- Material flammability
- Flame propagation
- Heat release
- Smoke density
- Toxicity of gases released during combustion
These requirements improve passenger safety while harmonizing fire protection standards across Europe.
Hazard Levels: HL1, HL2, and HL3
EN 45545-2 defines three Hazard Levels (HL) that determine the fire performance requirements applicable to railway materials.
HL1 – Low Risk
HL1 generally applies to vehicles operating under conditions that allow rapid passenger evacuation, such as certain trams and surface rail vehicles. Fire safety requirements remain significant but are the least stringent within the standard.
HL2 – Medium Risk
HL2 applies to most regional and intercity trains. It covers operating conditions where evacuation may be more challenging, particularly on routes including tunnels or areas with restricted access.
HL3 – High Risk
HL3 represents the highest level of fire safety requirements. It typically applies to metro systems, high-speed trains, and vehicles operating through long tunnels or environments where passenger evacuation is particularly difficult. Materials used in these applications must provide the highest level of fire performance.
How Is the Appropriate Hazard Level Determined?
The applicable Hazard Level depends on several operating characteristics of the railway vehicle, including:
- Operating speed
- Type of service
- Length and frequency of tunnels
- Evacuation conditions
- Passenger capacity
For example, an urban tramway will generally fall under HL1, whereas a sleeper train operating through long tunnels will often require HL3 compliance.
Why Choose EN 45545-2 Compliant Materials?
Compliance with EN 45545-2 has become a key requirement for modern railway projects. It not only ensures conformity with European regulations but also enhances passenger safety and improves the reliability of onboard equipment.
For manufacturers and railway system integrators, selecting components that comply with EN 45545-2 is a mark of quality. It also facilitates vehicle certification and simplifies approval for deployment across European railway markets.
