There is described systems and methods for managing an electrical surge of railway signaling equipment. A breaker includes a mechanical reset button that shifts positions in response to detecting the electrical surge exceeding a threshold amperage. An opto-isolator deenergizes in response to the position shift of the mechanical reset button. The event recorder transmits an alarm signal to a remote office system in response to the deenergizing of the opto-isolator.

The video monitoring system collects a video data stream in real time; the device inspection system collects and uploads an image of each electrical device along a line; the voice communication system realizes a voice call between an inspection staff and a back-end monitoring staff; the environmental monitoring system monitors a temperature, a humidity, and a water intake in the traction substation and each electrical device; the fire alarm system monitors a fire in the traction substation; the sulfur hexafluoride gas monitoring system monitors a sulfur hexafluoride gas leakage in an electrical device; the security prevention system collects alarm information; the power lighting monitoring system collects operation information of a power lighting device; the power monitoring system monitors an input current and voltage and an output current and voltage of the traction substation in real time. The information is transmitted to the railroad dispatching center.

A system for measuring motion of a locomotive vehicle includes a speed sensor, a decelerometer and an onboard processing unit. The speed sensor is configured to measure wheel speed of the locomotive vehicle. The decelerometer includes a level-sensitive device configured to measure acceleration or deceleration of the locomotive vehicle as a function of a tilt from a level position. The onboard processing unit computes a current grade traversed by the locomotive vehicle prior to detection of a slip or slide condition based on a first measurement signal from the decelerometer. Upon detection of the slip or slide condition, the onboard processing unit obtains a second measurement signal from the decelerometer and filters out the current grade from the second measurement signal. The onboard processing unit determines an actual acceleration or deceleration of the locomotive vehicle during the slip or slide condition from the filtered second measurement signal from the decelerometer.

A system and method for determining the location of a vehicle when GNSS signals are not available use triangulation between one or two radio transmitters and, respectively, two or one radio receivers mounted on the vehicle. The distance between each radio transmitter and/or each radio receiver can be determined according a phase difference between received radio signals. The radio signals can have the geographical location of the radio transmitter included therein. Utilizing the demodulated geographical location of each radio transmitter and the distance between the radio transmitter and each radio receiver, triangulation can be used to determine the geographical location of the vehicle.

A travel condition network information generation system includes: a travel condition output unit provided on the transport, and outputting a piece of travel condition data responsive to a travel condition of the transport; and a controller generating, based on a plurality of pieces of travel condition data, a plurality of pieces of divided travel condition information responsive to divided travel paths obtained by dividing a plurality of travel paths, and generating, based on the plurality of pieces of divided travel condition information, the travel condition network information corresponding to the travel path network of the transport.

A controller is provided that can receive or determine at least one first location associated with at least a first vehicle belonging to a vehicle group; receive or determine at least one second location associated with at least a second vehicle; and determine a route or lane from a plurality of possible routes or lanes on which the vehicle group is located based at least partly on the at least one first location and on the at least one second location.

Provided is a computer-implemented method for determining a communication status in a train consist operating in a distributed power system, the train consist including a lead locomotive and a plurality of remote locomotives. The method includes, for each remote locomotive of the plurality of remote locomotives that receives the command message directly from the lead locomotive, setting the message source indicator of the remote locomotive to a first state representative of a direct receipt of the command message, incrementing the message source counter for each response message received by the remote locomotive from other remote locomotives in which the respective message source indicator is set to the first state, generating a response message including a value of the message source indicator and a value of the message source counter, and transmitting the response message. A system and computer program product are also disclosed.

A vehicle includes one or more travel portions each configured to travel along a rail track, a travel controller configured to perform an image recognition to determine a shape of a portion of the rail track based on an image captured by an imaging device supported by the vehicle and to control the one or more travel portions based on a result of the image recognition, an information obtaining portion configured to obtain position information of each of a plurality of locations that the vehicle travels past as a result of traveling along the rail track, and to obtain the order in which the vehicle travels past such plurality of locations, and memory configured to store information obtained by the information obtaining portion.
