Abstract:
In a jointless track system, passive signaling devices (“PSDs”) are coupled to a railroad track. The PSDs are used to optimize the amplitude, modulation, coding, and frequency of waveforms that are applied to the track (by signaling points) for at least three track circuit functions: detecting trains, detecting broken rails, and communicating between the signaling points and PSDs.
