A method for controlling a main circuit of a traction system is provided. The method includes: under a braking condition, controlling a protection module to be turned off; controlling the protection module to be turned on and monitoring a first current detected by a first current sensor in a case that a rail vehicle runs on a charged third rail; and controlling the protection module to be turned off and monitoring whether the rail vehicle runs on a charged third rail in a case that the first current is less than a first preset current.

A triggering system for a train having a spotter control system is provided. The triggering system includes a position detection system configured to generate a position signal indicative of a position of a rail shop relative to the train. The system also includes a controller coupled to the position detection system, the spotter control system, and an engine of the train. The controller is configured to receive the position signal from the position detection system. The controller is configured to detect if the train is approaching the rail shop based on the position signal. The controller is configured to trigger a shutdown of the engine based on the detection. The controller is configured to trigger an activation of the spotter control system based on the detection.

A track verification and signal testing system includes a central remote location comprising a computer system, the computer system hosting multiple workstations and monitors allowing test engineers to control inputs, and to monitor outputs, signals, and information associated with the verification and testing of a railroad track installation The computer system is in communication via a communications link with one or more automated field simulators, or control point field emulators (CPFE), placed in one or more signal bungalows housing the signal system circuitry associated with one or more sections of track.

A method for indicating a status of a railroad switch is configured for use in un-signaled (dark) territory utilizing vital audio messages. In one embodiment, the method comprises receiving a DTMF signal from a railway vehicle, initializing control of the switch, and triggering the reporting of a correspondence condition through vital relays or other electronic components.

The rail bond monitor has a frequency transmitter to generate an electronic signal at a known energy level to pass through two or more impedance bonds located at an insulated rail junction between two sections of railroad tracks in order to allow a change in energy level, under analysis, at a receiver to be detected from an expected amount of energy level. An energy level detector is coupled to the receiver to detect the energy level under analysis at the receiver and compare that to the expected amount of energy level, and then generate a notice signal configured to trigger a relay output when the change in energy level under analysis is beyond a threshold amount. The relay output sends an output into a rail controller to warn that a problem exists with the impedance bonds themselves and/or the electrical paths between the railroad tracks and the impedance bonds, at a given insulated rail junction.

A railway asset tracking and mapping system stores positions and visual imagery associated with physical railroad assets such as signals, road crossings, platforms, and mile posts along a segment of a railway track and displays the geographic positions and imagery of those physical assets in simultaneous and correlated track chart, video imagery, and map formats on an integrated interactive display. An associated method of displaying correlated track chart, video imagery an map is also disclosed.

Disclosed herein is a method for indicating a status of a railroad switch used in un-signaled (dark) territory utilizing vital audio messages. In one embodiment, the method comprises receiving a DTMF signal from a railway vehicle, initializing control of the switch, and triggering the reporting of a correspondence condition through vital relays or other electronic components.

The system provides a railroad switch for use in un-signaled (dark) territory. In particular, the system includes a plurality of audio messages maintained on a discrete audio board, where a DTMF signal is validated, initializes the control of a switch, and triggers an audio board to report a correspondence condition, where the output of the audio board is checked by a relay status.
