What is TS 50701 ?
CLC/TS 50701 is the technical specification published by CENELEC for railway application cybersecurity. It adapts the IEC 62443 framework to the specific context of the railway sector, covering signaling, command-control, communication, and supervision systems. The standard defines security requirements for railway operators, system integrators, and component manufacturers. It introduces security levels adapted to the railway context and accounts for safety constraints inherent to passenger and freight transport.
Key Points
- Adaptation of IEC 62443 to the railway context: signaling, command-control, communication
- Consideration of security and safety interaction specific to railways
- Requirements for operators, integrators, and railway component manufacturers
- Zones and conduits approach adapted to railway system architecture
- Alignment with the NIS2 directive for European railway transport operators
Why Zaxyr
Zaxyr helps railway operators and integrators assess their TS 50701 compliance by structuring analysis by system (signaling, control, communication). The platform provides mapping to IEC 62443 and NIS2, enabling unified management of railway OT compliance and European regulatory obligations.
