SIST EN 45545-6:2025+A1:2026 is the SIST standard identical to EN 45545-6:2024+A1:2026 for railway applications. It specifies fire control and management systems for railway vehicles, including fire detection, alarms, equipment shutdown, emergency brake-related functions, communication, and fire fighting measures. The document applies to railway vehicles covered by EN 45545-1:2013 and is aimed at protecting passengers and staff during an onboard fire.
What does SIST EN 45545-6:2025+A1:2026 specify?
SIST EN 45545-6:2025+A1:2026 sets requirements for how railway vehicles detect fire, warn people, control energy and ventilation, and provide fire fighting means. It also sets how those systems must keep working during the fire incident.
| Annex | What it covers |
|---|---|
| Annex ZA | Relationship between this European Standard and the Essential Requirements of EU Directive (EU) 2016/797 |
The document is organized into Clause 1 Scope, Clause 2 Normative references, Clause 3 Terms and definitions, Clause 4 General requirements, Clauses 5 and 6 for automatic and manual processes, Clause 7 for operation under fire conditions, Clause 8 Evaluation of conformity, and informative Annex ZA.
What are the key requirements of SIST EN 45545-6:2025+A1:2026?
Automatic fire detection and alarms
Clause 5 requires fire detection devices to be on and in use when the vehicle is occupied, and to monitor the areas and equipment listed in Table 1. The devices must suit the expected fire products, such as flames, smoke, and heat, so in practice the detector type has to match the fire risk in each zone.
When a detector activates, Clause 5 requires a local alarm and a remote alarm, and then the specified automatic responses. The local alarm applies in the relevant design categories and must be audible, with visibility where needed; in sleeper compartments it must be able to wake a sleeping occupant.
The remote alarm must alert the driver, or the control centre for design category A, and it must show the location of the activation. This matters because staff need to know where the fire started before they decide on intervention.
Automatic responses to a fire signal
Clause 5 requires selective shut down of energy in primary and secondary cases. In practice, this means the vehicle must remove energy from the equipment involved, but not from systems that must keep working for the fire incident.
Ventilation in passenger and staff areas with automatic fire detection must have a shut-down facility or smoke exhaust mode. Clause 5 also requires powered photoelectric fire barrier doors to lose power if smoke could make them open when they should stay closed.
Where a fire barrier door is held open, it must close automatically or by manually initiated remote control when fire is detected. Clause 5 also identifies where fixed fire fighting equipment is required and requires local alarms with enough delay before discharge if the extinguishing system could endanger people.
Manual processes and portable fire fighting
Clause 6 requires passenger alarm systems to comply with EN 16334-1:2014+A1:2022. For trains outside the scope of Directive (EU) 2016/797, the system must use at least one of three approaches: influence braking, alert staff, or enable voice contact with staff.
Clause 6 also limits what passengers can do with the emergency brake: passengers must not be able to stop the train without staff intervention to keep it running to an appropriate stopping point. Voice contact must allow bi-directional communication and identify the contact location.
For portable fire fighting, Clause 6 requires suitable extinguishers at appropriate locations, with limits on weight, visibility, access, and placement. Special locations include each driver’s cab, the ends of vehicles in design categories S and DS, cooking areas, and areas near combustion equipment.
Performance under fire conditions
Clause 7 requires any process started under Clause 6 to continue to completion, or to remain in its end condition for as long as the fire incident requires. The systems involved need sufficient fire integrity and/or redundancy, and their ability to meet this requirement must be verified by system analysis.
What terms does SIST EN 45545-6:2025+A1:2026 define?
Clause 3 refers to the terms and definitions in EN 45545-1:2013. In practice, the document uses a small set of recurring terms that shape the requirements:
- Design category - the category used to decide which fire protection requirements apply to a vehicle or area.
- Passenger alarm system - the system that allows passengers to alert staff and receive information back from staff.
- Remote alarm - the alarm sent to the driver or control centre after automatic fire detection.
- Selective shut down of energy - the controlled removal of power from selected equipment so the fire is not fed by extra energy.
- Held-open fire barrier door - a door that is kept open in normal use but must close when fire is detected.
- Fixed fire fighting equipment - installed fire suppression equipment intended to protect a defined vehicle area.
- Fire extinguishing media - the substance used to extinguish the fire, chosen for the fire class and area of use.
Who uses SIST EN 45545-6:2025+A1:2026?
Railway vehicle designers, fire safety engineers, rolling stock manufacturers, system integrators, and conformity assessors use this standard when designing and checking fire detection, alarms, shutdown logic, fire doors, extinguishers, and fixed suppression systems. Operators, buyers, and quality managers use it to specify equipment and verify that a vehicle’s fire control functions match the required vehicle category and operating context.
What changed in SIST EN 45545-6:2025+A1:2026 from the previous edition?
SIST EN 45545-6:2025+A1:2026 supersedes SIST EN 45545-6:2025 and incorporates Amendment 1. The foreword says the amended text is marked in the document.
Which standards are used with SIST EN 45545-6:2025+A1:2026?
- EN 45545-1:2013 - gives the general fire protection framework and the terms and definitions used here.
- EN 45545-2:2020+A1:2023 - supports the fire behaviour requirements for materials and components.
- EN 45545-3:2024 - supports fire resistance requirements for fire barriers and fire barrier doors.
- EN 16334-1:2014+A1:2022 - sets passenger alarm system requirements.
- EN 50553:2012 - provides validation related to running capability in case of fire and the timing of fire-related actions.
- EN 54-3:2014+A1:2019 and EN 54-23:2010 - support sounders and visual alarm devices.
- EN 3-7:2004+A1:2007, EN 3-8:2021, EN 3-9:2006, EN 3-10:2009, and EN 2:1992 - support portable extinguishers and fire class rating.
- EN 1869:2019 - supports fire blankets.
- EN 61310-1:2008 - supports visual, acoustic, and tactile safety signals.
What does the SIST EN 45545-6:2025+A1:2026 document contain?
The document contains requirement tables for fire detection, selective shut down of energy, and fixed fire fighting equipment, each organized by design category and vehicle area. It also contains procedures for alarms, extinguisher placement, and response logic for automatic and manual fire actions. Annex ZA gives the legal correspondence with Directive (EU) 2016/797, which is useful when the standard is used for railway interoperability and conformity work.

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.

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.
