SNCF adopts ACS25 for Field Tests in Traction Substations
SNCF has successfully deployed LEROY's most advanced and highly-secured ACS25 control-command solution in fixed electrical traction substations.

This product integrates the most stringent requirements from the prestigious SNCF authority, and passed very demanding approbation tests for nearly 24 months.

Field tests are now running successfully since the first quarter of 2016 in the Invalides substations in Paris, France. Such SNCF homologation testing period will last for one full year.

The ACS25 is the next system generation for existing programmable logic control (PLC) units. It offers better product reliability and maintenability, as well as higher system availability and intrinsic safety features ; while matching very optimized cost of ownership.
