EN 45545-6:2024+A1:2026 is a CEN European Standard for railway applications. It specifies fire control and management systems on railway vehicles, including fire detection, alarms, energy shutdown, communication, emergency brake-related functions, and fire fighting measures that protect passengers and staff during an onboard fire.
What does EN 45545-6:2024+A1:2026 specify?
EN 45545-6:2024+A1:2026 sets requirements for fire control and management systems on railway vehicles covered by EN 45545-1:2013. It focuses on how a vehicle should detect fire, warn people, limit fire growth, and support evacuation and response.
The document is organized into clauses 1 to 8, plus informative Annex ZA and a bibliography. Clause 1 gives the scope, Clauses 4 to 7 contain the technical requirements, and Clause 8 points to conformity evaluation in EN 45545-1:2013.
The standard covers fire detection, alarm systems, equipment shutdown, information and communication systems, emergency brake systems, and fire fighting systems. It does not address measures for preserving the vehicle itself in a fire.
What are the key requirements of EN 45545-6:2024+A1:2026?
The core idea is simple: when fire is detected, the vehicle must warn people, stop feeding the fire where appropriate, and keep the safety functions working long enough to finish their task. In practice, this affects how equipment is designed, placed, powered, and verified.
Fire detection and alarm response
Clause 5 requires fire detection devices to be active when vehicles are occupied and to monitor the areas listed in Table 1. They must suit the expected fire products, such as flames, smoke, and heat, and their verification must consider the fire origin, size, materials involved, detector type, and airflow.
When a detector operates, an automatic local and/or remote alarm must be triggered, and the alarm timing follows EN 50553. Local alarms apply in design categories D, S, and DS in the affected vehicle area, including sleeper compartments, where the alarm must be able to wake a sleeping occupant. Remote alarms must alert the driver or, for design category A, the control centre, and indicate the activation location.
Energy shutdown and smoke control
Clause 5.4 requires selective shut down of energy supply. The aim is to stop extra energy from feeding the fire, avoid secondary hazards from failing equipment, and help fire fighting. Ventilation in passenger and staff areas must have a shut-down or smoke exhaust function that is activated by automatic detection.
Powered fire barrier doors and held-open fire barrier doors have specific fire-response duties. The door control must react so that smoke or fire does not leave the door open when it should be closed. Automatic public address messages must stay audible and understandable under normal operating noise.
Fixed and portable fire fighting
Clause 5.4.4 identifies where fixed fire fighting equipment is required, based on design category and affected areas. Where a discharge could expose passengers or staff to hazards, local visible and audible alarms and a delay for evacuation are required.
Clause 6.3 covers portable extinguishers. They must be suitable for their intended use, comply with the EN 3 series, remain usable in service, and be placed within the stated access distances. Specific locations are required in driver’s cabs, some passenger vehicles, cooking areas, and near certain combustion equipment. Fire blankets are required where fat or oil frying is carried out.
Manually initiated processes and system integrity
Clause 6 requires passenger alarm systems to comply with EN 16334-1:2014+A1:2022. For trains outside Directive (EU) 2016/797, the document allows three alarm approaches: influence the braking system, alert staff, or enable voice contact with staff.
Clause 7 requires safety-related processes triggered by fire to continue to completion or remain in their end state for as long as needed. The supporting functions need sufficient fire integrity and/or redundancy, and this is checked by system analysis.
What terms does EN 45545-6:2024+A1:2026 define?
The document uses the terms and definitions from EN 45545-1:2013. Key terms used in the requirements include:
- Passenger alarm system - the system used by passengers to warn staff and receive information back from staff or the control centre.
- Selective shut down of energy supply - targeted removal of power from selected equipment to limit fire growth and secondary hazards.
- Fixed fire fighting equipment - installed suppression equipment intended to protect specific vehicle areas or equipment.
- Fire barrier door - a door that must close in response to fire conditions, including self-closing and powered types.
- Automatic detection - fire detection that starts alarm and response actions without manual initiation.
- Design category - the operating category used to decide which requirements apply in Tables 1 to 3.
Who uses EN 45545-6:2024+A1:2026?
EN 45545-6:2024+A1:2026 is used by rolling stock designers, vehicle manufacturers, fire safety engineers, subsystem suppliers, and conformity assessment bodies. It is also relevant to operators and maintenance teams who need to specify, verify, or inspect fire detection, alarms, extinguishers, and shutdown functions on railway vehicles.
What changed in EN 45545-6:2024+A1:2026 from the previous edition?
EN 45545-6:2024+A1:2026 includes Amendment 1 and supersedes EN 45545-6:2024. The document marks text introduced or altered by the amendment in the body of the standard.
Which standards are used with EN 45545-6:2024+A1:2026?
The main referenced standards are:
- EN 45545-1:2013 - provides the overall fire protection framework, vehicle applicability, and terms and definitions.
- EN 45545-2:2020+A1:2023 - supports requirements for fire behaviour of materials and components.
- EN 45545-3:2024 - supports fire resistance requirements for fire barriers and some cabinet conditions.
- EN 16334-1:2014+A1:2022 - gives passenger alarm system requirements.
- EN 50553:2012 - provides validation and fire-running capability related timing.
- EN 54-3:2014+A1:2019 and EN 54-23:2010 - support audible and visual alarm performance.
- EN 3-7, EN 3-8, EN 3-9, EN 3-10 and EN 2:1992 - support portable extinguishers and fire class ratings.
- EN 1869:2019 - supports fire blanket selection.
- EN 61310-1:2008 - supports safety signs and marking for extinguisher location.
What does the EN 45545-6:2024+A1:2026 document contain?
The document contains three requirement tables for fire detection, selective energy shut down, and fixed fire fighting equipment, each linked to design and operation categories. It also contains rules for alarm response, ventilation control, extinguisher placement, and fire-safe continuation of systems during an incident.
Annex ZA gives the relationship with Directive (EU) 2016/797 and identifies the clauses used for presumption of conformity in the EU context.

4 General requirements
The design, construction or assembly of components which are critical for fire safety, e.g. for fire detection
and for fire fighting, shall comply with the objectives in EN 45545-1:2013.
All passenger vehicles shall be fitted with a passenger alarm system to inform on-board staff and/or
control centre staff about a possible fire detected by a passenger.
All passenger vehicles shall be equipped with a passenger alarm system that provides a means of
conveying information to passengers from on-board staff or control centre staff.
NOTE For architecture of passenger alarm system refer to EN 16334-1:2014+A1:2022.
Fire barrier doors for passenger use shall be of the self-closing type. Fire barrier doors have to be
compliant with EN 45545-3:2024.
Powered fire barrier doors for passenger use shall stop in a closed position when a fire is detected in one
of the adjacent areas (automatic or manual detection).
As impacted by EN 50553:2012/AC:2013, EN 50553:2012/A1:2016 and EN 50553:2012/A2:2020.
5 Requirements for systems used in automatically initiated processes
5.1 General
When applicable, the process steps are automatic detection, leading to alarm and leading to action.
5.2 Fire detection
Fire detection devices shall be switched on and in use when railway vehicles are occupied. They shall
monitor the areas or equipment specified in Table 1. Fire detection devices shall be functionally suitable
for the expected fire products, e.g. flames, smoke and heat.
The following points shall be taken into consideration for the verification of functionality:
1) the origin of the fire;
2) the size of the fire;
3) the materials involved in the fire;
4) the nature of any detectors;
5) the air flow.
