CENELEC EN50126, EN50128 and EN50129

2 Day Course

Digital Rail offer a two-day in-depth workshop for engineers, managers and other rail decision makers to learn about CENELEC EN 50126, EN 50128 and EN 50129. The workshops will help attendees expand their knowledge and make better decisions around the standards and their application in the area of railway safety, to reduce total deployment costs, and streamline and de-risk development.

CENELEC EN 50126/8/9 influence all stages of the development of railway systems as mandatory railway industry standards, from concept to deployment, certification and maintenance. Their goal is to provide greater interoperability and increased safety, reliability, availability and maintainability of railway systems. A thorough practical knowledge of the requirements of these standards is essential for the successful certification of railway systems with the appropriate authorities.

Our CENELEC training provides a complete overview of the most important European railway standards, with well-structured presentations and frequent discussion sessions ensuring that attendees get the most from participating.


  • Demonstrate a sound understanding of the principles of CENELEC, including reliability and safety
  • Appreciate risk in the context of railway design and safety management
  • Describe how design and the safety lifecycle interact and influence each other
  • Relate current best practice in EN 50126/8/9 to real business contexts
  • Understand the concepts of THR and SIL
  • Describe different approaches to risk acceptance and ALARP
  • Understand system safety, systems engineering and integration, validation and stakeholder management, in the context of the rail industry


  • An overview of EN 50126 (IEC 62278:2002), EN 50128 (IEC 62279:2002) and EN 50129 (IEC 62425:2007-09), looking at their relationships
  • The role of the European Railway Agency and the safety directives and significance of the CENELEC standards
  • What functional safety is and how we can control random and systematic failure using the concepts of Safety Integrity Level (SIL) and Tolerable Hazard Rates (THR)
  • The safety-case approach to demonstrating safety
  • The safety lifecycle model, risk analysis and THR/SIL determination and allocation for hardware and software
