We are celebrating a significant advancement in the modernization of Paris Metro Line 4 with the full automation of train operations. This technological challenge required, among other things, the implementation of a Train Operation Automation System (SAET).

As a trusted partner of RATP for over twenty years, Systerel has contributed to the validation of the line’s configuration data and the evaluation of the safety of the SAET system. With each commissioning, Systerel ensures that the modifications made to the data comply with the safety rules and requirements identified in the project and accordingly updates all data validation activities for the line.

In addition to these works, Systerel is also conducting data validation work for the SAET system of Line 14 and for the OCTYS system of Lines 6 and 11.

We are proud to contribute to these innovative projects alongside RATP that are shaping the future of the railway sector. Many major players in the railway industry entrust us with data validation or independent evaluations for safety equipment.
