Abstract: A monitoring device monitoring a railway track, including a track interface connecting the monitoring device to the railway track. Also included is a detector detecting a first track pulse having a first duration emitted on the railway track and received through the track interface. The detector can detect a start and end time of the first track pulse. A charger is connected to the detector and has an energy storage element. Further, there is an emitter emitting a second track pulse on the railway track through the track interface by using energy stored in the energy storage element and the detector can send a transmit control signal to the emitter.

Abstract: A system includes a signal system controller electrically connected to a first track section of a first rail of a track system, and electrically connected to a second track section of the first rail, in which the first track section is separated from the second track section by a first rail insulated joint. The signal system controller is configured to transmit a test signal on the first track section and configured to receive the test signal on the second track section to test the first rail insulated joint between the first track section and the second track section.
