Overview

SIST EN 45545-6:2025+A1:2026 is a European standard developed by the Slovenian Institute for Standardization (SIST) addressing fire protection measures for railway vehicles, specifically focusing on fire control and management systems. This document forms part of the EN 45545 series, which establishes methods and requirements to enhance fire safety and safeguard passengers and staff during onboard fire incidents. Part 6 of the series details requirements for systems such as fire detection, alarm systems, equipment shutdown, communication, emergency braking, and fire fighting, as covered in the broader scope of EN 45545-1:2013.

The standard is applicable to all railway vehicles defined in EN 45545-1:2013 and aims to alert occupants to fire, delay fire progression, and control smoke movement, thereby mitigating risks to human life.

Key Topics

• Fire Detection and Alarm Systems

  • Requirements for automatic and manual fire detection in key areas (passenger spaces, technical cabinets, cooking areas, etc.)
  • Specification for audible and visible alarms to ensure effective warning under varying operational conditions

• Emergency Information and Communication

  • Integration of public address and passenger alarm systems to facilitate communication between staff and passengers during emergencies
  • Requirement for bi-directional voice contact and identification of alarm location

• Equipment Shutdown and Smoke Control

  • Mandate for selective shutdown of energy to affected equipment to prevent exacerbation of fire hazards
  • Control of HVAC and ventilation systems to limit smoke propagation

• Barrier Doors and Compartmentalization

  • Requirements for fire barrier doors to be self-closing and compliant with EN 45545-3:2024, facilitating containment of fire and smoke

• Emergency Braking and Staff Intervention

  • Passenger alarm systems interfacing with braking systems and staff notification to ensure coordinated emergency response

• Fixed and Portable Fire Fighting Equipment

  • Stipulations for the provision, placement, and type of portable extinguishers and fixed fire suppression systems
  • Consideration for appropriate fire classes and placement to maximize accessibility and effectiveness

Applications

The requirements of SIST EN 45545-6:2025+A1:2026 are vital for entities involved in the design, construction, operation, and maintenance of railway rolling stock. Key practical applications include:

• Enhanced Safety Systems for Modern Trains

  • Integrating compliant fire detection, suppression, and alarm infrastructure into new and existing railway vehicles
  • Ensuring quick detection and communication to significantly improve emergency response times

• Operational Safety for Staff and Passengers

  • Empowering staff with timely information and control measures to manage on-board fire incidents efficiently
  • Providing clear evacuation instructions and safe communication channels during emergencies

• Facilitating Regulatory Compliance

  • Supporting manufacturers and operators in meeting essential requirements of EU Directive (EU) 2016/797 on rail system interoperability
  • Aligning with national and European assessment procedures for conformity and certification

• Risk Mitigation for Complex Rolling Stock

  • Addressing additional hazards for trains with technical cabinets, lithium-ion batteries, or advanced onboard equipment
