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).

A positive train control may comprise a plurality of different sensors coupled to a processor that determines whether there is an anomaly of a track way, and if there is, provides an alert and/or a train control action. The plural sensors may include a visual imager, an infrared imager, a radar, a doppler radar, a laser sensor, a laser ranging device, an acoustic sensor, and/or an acoustic ranging device. Data from the plural sensors is geo-tagged and time tagged. Some embodiments of the train control employ track monitors, switch monitors and/or wayside monitors, and some employ locating devices such as GPS and inertial devices.

An interlocking device performs route control for trains based on: first operation diagram information as train operation diagram information on a train which runs between stations; second operation diagram information as train operation diagram information on a train which moves in a station yard; and on-track position information on the trains. The interlocking device performs control with time on a signal and/or a switch on a route of a train based on different information according to whether a predetermined condition is satisfied.

A wireless train control system includes: a device that generates a track circuit state signal indicating whether a track circuit is picked up or dropped and a time-triggered track circuit state signal indicating a drop at a timing delayed by a set time after the track circuit state signal indicates that the track circuit is dropped; and a controller that generates a stop limit point of a wireless-control-compliant train by using presence information if a preceding train is a wireless-control-compliant train, and generates the stop limit point by using the track circuit state signal and the time-triggered track circuit state signal if the preceding train is a non-wireless-control-compliant train. The controller does not update the stop limit point if the track circuit state signal indicates that the track circuit is dropped while the time-triggered track circuit state signal indicates that the track circuit is picked up.
