EN-50126/50128/50129 – RAMS Red Belt Certification

Course Identifier:  e40-001

The standards EN 50126, EN 50128 and EN 50129 provide railway duty holders and railway suppliers with a process which will enable the implementation of a consistent approach to the management of Reliability, Availability, Maintainability and Safety (RAMS).

EN 50126/8/9 forms part of the railway sector specific application of IEC 61508.

This training guides you through the structure of these standards and helps you to clearly understand the development life cycle, actors, processes, activities and deliverables to be prepared at each stage. During the course, several examples and exercises will be undertaken in order to ensure the correct understanding of all requirements.

Our course is structured in 3 main blocks (System, SW and HW/Signaling). Each blocks takes place on a different day, allowing trainees to book one or multiple days, depending on their needs. However, the exam given the third day requires that all training days (1-to-3) have been followed by the trainee.
