Successful commisioning of SNCF switching relays

Our switching relays are deployed on the Paris-Lyon high speed line, in Marne la Vallée !

Within the framework of the modernization of the safety installations of the Paris-Lyon High Speed Line, SNCF Réseau wished to develop a system allowing to switch automatically in SIL2 safety of the campaign signals between an old station (AP) and a new station (NP). Our Marseille Agency has therefore developed a MEY (Mise en Y) relay switching system that will save time on the various tests. It is easily dismantled and reused.

Following the EMC test campaign successfully carried out according to the 50121-4 standard on the prototypes and after 1 year of development, the first experimentation tests in collaboration with the SNCF Réseau team have started in a new PR CI 73 signal box in Marne-la-Vallée.

The goal is to verify the operation of the switching relays and the absence of errors, using a recorder over a period of 1 month.
The design of the equipment was very appreciated. Its installation is quick and its handling simple. The feedback on this test campaign is very positive.
Since then, we have been authorized to deliver the equipment in series in order to install them in the signal boxes.

You will find some pictures of the experimentation !
