CAB SIGNALLING SYSTEM UTILIZING CODED TRACK CIRCUIT SIGNALS

摘要

A railway vehicle cab signalling system providing electrical signals to operate an aspect display unit or the like located on-board a railway vehicle based upon the track circuit signals typically used to operate wayside indicators. Sensor means detect the track circuit current as it passes through at least one wheel and axle set on the vehicle. Processing means receive an output signal from the sensor means and produce a signal to operate the aspect display unit.
