Stadler is supplying RATP with maintenance trains that must be fully compatible with the Paris network’s signaling system. The goal is to ensure the proper functioning of the automatic train stop system when trains pass through restricted signals, in order to enhance the safety of maintenance vehicles and operations.
In this context, CLEARSY is developing a custom SIL2 safety solution that ensures trains stop automatically when passing through restrictive signals. This solution allows safety functions to be effectively integrated into new rolling stock without modifying the existing track-side system.
This project illustrates the challenge of adapting new trains to an existing signaling infrastructure while maintaining a high level of safety and reliability across the network.
