A device 10 for a track bound monitoring system for monitoring conditions on a railway track 28 comprising a first rail 26 and a second rail 30 comprises a signal generation unit 12 having an output 13. The signal generation unit is configured to generate an electrical monitoring signal having a monitoring signal characteristic. The output is connectable to at least one of the first rail and the second rail. A sensing unit 16 has an input 17 which is connectable to at least one of the rails. A controller 20 is connected to the generation unit and the sensing unit and is configured to cause the generation unit to generate the monitoring signal which propagates in the first rail and to receive from the sensing unit a return signal. The return signal is derived from the monitoring signal and has a return signal characteristic. The controller is configured to utilize a time difference between the monitoring signal characteristic and the return signal characteristic to monitor conditions on the railway track.

A system (100) and method is provided that facilitates controlling signaling devices along railroad tracks in electrified territory. The system may include a first track circuit transmitter (116) connectable to a first end (160) of a first block (162) of a railroad track (180). A first processor (104) may be configured to determine a first signaling aspect (112) corresponding to a visible light signal outputted by a first signaling device (110) and cause the first track circuit transmitter to transmit a first code (166) corresponding to the first signaling aspect via a first AC carrier signal (164) through rails (182, 184) of the first block of the railroad track. The system may also include a first track circuit receiver (134) connectable to a second end (168) of the first block of the railroad track, which is configured to receive the first AC carrier signal through the rails of the first block of the railroad track and demodulate the first code from the first AC carrier signal. A second processor (124) may be configured to determine a second signaling aspect (132) based at least in part on the first code that was demodulated and cause a second signaling device (130) to output a visible signal corresponding to the second signaling aspect.

The present invention refers to a method for detecting a break in a railway track, system for detecting a break in a railway track (1) and device for detecting a break in a railway track (500), in which a first track (101) and a second track (102) are connected defining measuring sections (302, 303) and electrical detection networks (M1, M2), in which a device for detecting a break in a railway track (500) is coupled to said tracks (101, 102) and arranged to measure at least one electrical parameter of at least one electrical detection network (M1, M2) and selectively promote an output (502) that indicates a state of at least one track (101, 102).
