Overview
EN 15227:2020/FprA1 - "Railway applications - Crashworthiness requirements for rail vehicles" (CEN) specifies passive crashworthiness requirements for new designs of locomotives, driving vehicles used in passenger and freight trains, and passenger rail vehicles (trams, metros, mainline trains). The standard defines common passive safety methods, design collision scenarios, and reference obstacle models, and it sets out accepted demonstration routes (comparison with proven designs, numerical simulation, component or full‑size tests, or combinations).
Key topics and technical requirements
- Scope and applicability: Requirements apply to new vehicle designs across multiple vehicle categories (locomotives, driving vehicles, passenger rolling stock).
- Design collision scenarios: Standard identifies collision scenarios to be addressed and links them to specific obstacle models used in design verification.
- Reference obstacle models: Characteristic deformable and rigid obstacle models are specified to ensure consistent assessment of structural behavior in collisions.
- Passive safety objectives: Defines structural and energy‑management strategies to protect occupants and reduce injury risk without requiring active systems.
- Compliance demonstration methods:
- Comparison with existing proven designs
- Numerical simulation (finite element analysis)
- Component tests or full‑size crash tests
- Any suitable combination of the above
- Terminology and interfaces: Updates in the amendment replace terms such as “heavy duty coupler” with “centre buffer freight coupler”, and update normative references (e.g., EN 12663‑1, EN 15663, EN 17343).
- Regulatory alignment: Annex ZA maps the standard to the Essential Requirements of EU Directive (EU) 2016/797 and related TSIs for rolling stock interoperability.
Practical applications
- Vehicle structural design: Informing crash‑resistant bodyshell design and energy‑absorbing structures.
- Safety verification: Defining the scenarios and obstacle models used for simulation and test programs.
- Certification & compliance: Providing a voluntary harmonized means to demonstrate conformity with TSI requirements where cited in the Official Journal.
- Procurement and specification: Operators and authorities can reference EN 15227 when specifying crashworthiness for new fleets.
Who uses this standard
- Rolling stock manufacturers and OEMs
- Structural and crashworthiness engineers
- Simulation specialists and test laboratories
- Certification bodies and regulatory authorities
- Rail operators and procuring agencies focused on vehicle safety and TSI compliance
Related standards
- EN 12663‑1 (structural requirements of vehicle bodies)
- EN 15663 (vehicle reference masses)
- EN 17343 (general terms and definitions)
- EU Directive/TSI: Directive (EU) 2016/797 and related Technical Specifications for Interoperability
EN 15227:2020/FprA1 is essential reading for professionals designing, validating, or certifying crashworthy rail vehicles and for stakeholders aligning vehicle design with European interoperability and safety expectations.
