The HaslerRail Cold Movement Detector (CMD) covers all ETCS functional requirements. When it comes to the ETCS on-board system, knowing whether a vehicle has been moved during the power off phase is crucial.

The CMD delivers a SIL4 function to supervise vehicle movement during the power off phase, transmitting the information to the ETCS on-board system, saving time and lowering operating costs. Drivers no longer have to operate in downgraded mode until the next coordination location to synchronize their positions with the wayside ETCS beacon.

Finally, with the CMD it is possible to reliably determine if a vehicle has been moved during the power off phase of the ETCS on-board system.

The solution is suitable for any rail vehicle equipped with an on-board ETCS system, from main-line locomotives and high-speed trains to suburban units and more.
