True speed calibration unit (TSCU)

True speed calibration unit (TSCU)

The TSCU is a module that is inserted between the axle speed pickup and the locomotive speed indicator. The TSCU uses the Global Positioning System (GPS) signals to generate a speed signal correction factor that automatically corrects the speed indicator signal thus providing an exact speed indication regardless of wheel wear.
