Course Overview

Functional safety ensures that safety risks due to hazards caused by the malfunctional behavior of systems are reduced to an acceptable level. These safety risks are increasing in the rail industry as rail technology is becoming more and more complex, with both hardware and software interacting in different ways and components that are sourced from multiple markets.

Successful completion of the course exam is required to receive a TÜV SÜD Academy certificate for this course.

This 4-day course includes the following standards with an exam on the final day:

  • EN 50126 (IEC 62278): Specification and Demonstration of Reliability, Availability, Maintainability and Safety (RAMS)
  • EN 50129 (IEC 62425): Safety related electronic systems for signaling
