High-speed train testing can require normal onboard safety functions to be temporarily disabled or bypassed to validate vehicle behavior beyond normal operating conditions. In these situations, the test train needs an independent protection layer capable of reacting autonomously if the predefined safety envelope is exceeded.
Developed and deployed in collaboration with SNCF Connect, ESVE continuously compares train speed with its position on the track and automatically commands emergency braking when predefined limits are exceeded. Built on the proven U-TEST® real-time platform, it combines deterministic processing, railway-grade hardware, onboard diagnostics and data recording in a compact embedded system designed for demanding railway test environments.
