The railway industry is a fascinating combination of complex locomotives, signalling systems, passenger and cargo cars and tracks.
The railway and rolling stock industry has challenging requirements for safety and reliability in order to prevent severe safety events.
Furthermore, there is a rising demand for public transportation with high QoS (quality of service).
Therefore, safety and reliability have to be integrated in the design process of rolling stock, signalling systems and tracks.
EN 50126, 50128 and 50129 document the path to RAM (Reliability, Availability and Maintainability) and Safety analyses of rolling stock and related systems.
Another challenge is to optimize maintenance of trackside equipment which is spread over long distances.
Reducing equipment restoration time is important for QoS as well as for safety (as restoration time increases, so does the probability for occurrence of a dangerous combination of failures).
