Overview

EN 50159:2010/A1:2020 is the CENELEC amendment that updates the European standard for safety-related communication in transmission systems used in railway applications. Prepared by CLC/SC 9XA and approved in July 2019, this Amendment A1 was published in February 2020 and mandates national implementation timelines (latest national implementation/withdrawal date 2020-08-07). The standard supports conformity to the CCS TSI and the essential requirements of EU Directive 2016/797/EU through its informative Annex ZZ.

This standard covers high-level requirements and guidance for achieving safety assurance in communications used by signalling, communication and processing systems. It is published in three official languages (English, French, German) and may be adopted in national languages by CENELEC members.

Key Topics

• Scope and Purpose: Defines the scope for safety-related communication in transmission systems applied to railway signalling and processing subsystems.
• Amendment A1: Modifies EN 50159:2010 and clarifies relationships with interoperability and regulatory requirements.
• Relationship to CCS TSI and EU Law: Annex ZZ maps clauses of EN 50159 to the essential requirements of Directive 2016/797/EU and the CCS TSI (Commission Regulation (EU) 2016/919), providing a presumption of conformity when cited in the Official Journal.
• Implementation Guidance: Provides context for national adoption and highlights that certain elements may be subject to patent rights.
• Stakeholders: Relevant to signalling engineers, system integrators, manufacturers, assessors and authorities responsible for railway interoperability and safety.

Applications

EN 50159:2010/A1:2020 is applied where safety-critical data is transmitted across communication links within the rail domain. Practical uses include:

• Designing and specifying transmission links for control-command and signalling subsystems.
• Demonstrating compliance for interoperability constituents and subsystem assessments under CCS TSI.
• Informing safety cases for signalling projects that require validated, safety-related communications.
• Guiding procurement and acceptance testing where communication integrity, detection of errors and assurance of safety-related message handling are required.

Benefits include clearer alignment with EU interoperability regulations, enhanced confidence in safety-related transmission design decisions, and improved harmonization across national implementations.

Related Standards

• EN 50159:2010 (base standard modified by A1)
• CCS TSI (Commission Regulation (EU) 2016/919) - Control-Command and Signalling Technical Specification for Interoperability
• Directive 2016/797/EU - Interoperability of the rail system

For implementers and procurement teams, EN 50159:2010/A1:2020 is a central reference for establishing compliant, safety-oriented communication strategies in modern rail signalling and transmission projects.
