Our contributions to rail networks and underground lines
A key player in the evolution of rail transport
Since the late 1990s, we have contributed to the equipment of several metro lines in Paris, marking a turning point in the modernisation of urban transport and passenger safety.
Since 1985, our relays have been integrated into TGV systems, performing essential functions such as:
- Brake management
- Door control
- Speed regulation
Thanks to our collaboration with major international manufacturers, our solutions are now used in trains in South Korea, China, Mexico, Morocco, Italy and Saudi Arabia.
Optimised fixed railway infrastructure
We also work on the fixed infrastructure of the railway network with solutions tailored to:
- Mainline trains (signalling, level crossings, electrical substations)
- Urban transport (automation of platform doors, smoke extraction, electrical network management)
