There is provided a ranging system for a railway vehicle. The system includes a reflector disposed along a railway relative to a stopping point and a ranging unit disposed on the railway vehicle. The ranging unit includes a transceiver configured to transmit an outbound signal and receive a corresponding reflected signal from the reflector. The ranging unit also includes a data storage unit configured to store a reference distance between the reflector and the stopping point. The ranging unit also includes a processor configured to determine a measured distance between the railway vehicle and the reflector based on an elapsed time between the transmitting the outbound signal and receiving the reflected signal. The processor determines a distance between the railway vehicle and the stopping point based on the measured distance and the reference distance.
