FIELD: railway roads.
SUBSTANCE: invention relates to monitoring the technical condition of a railway track. The system includes a lot of sensors installed on a rail of a railway track and located at a predetermined interval from each other. The sensors have appropriate signal acquisition and recording means for receiving and recording an acoustic signal generated by an approaching train and propagated by the rail or ground supporting the rail, signal transmission means for transmitting the received and recorded signal to the passing train by wireless transmission while the train is passing in the vicinity of the sensors; and signal analysis means for analyzing the transmitted signals from the received and recorded signals on board the passing train. The signal analyzing means can be adapted to compare signals from adjacent sensors in the processing unit and, on this basis, indicate a discontinuity in the rail.
EFFECT: increased safety of railway traffic.
