CLEARSY supplies Hitachi Rail with its SIL4 safety network

4 June 2025

Hitachi Rail works with CLEARSY, which supplies a SIL4 input/output safety network developed in France.

This technology enhances the safety of critical installations, while meeting the most stringent requirements in terms of operating reliability. CLEARSY is proud to contribute its unique expertise in safety systems engineering.

Hitachi Rail continues to expand its urban transit business in North America, equipping several subway and light rail lines with its advanced SelTrac™ CBTC (Communication-Based Train Control) signaling system, inherited from Thales expertise.

This system, recognized for improving the punctuality, safety and frequency of rail services, has been selected on several major projects: in New York for the Metropolitan Transportation Authority (MTA) to modernize the Crosstown line, in Toronto for the new Finch West streetcar line.
