Abstract: A system for controlling one or more vital wayside devices of a railway network, comprising one or more vital switches, each vital switch being comprised in or operatively connected to an associated device of the one or more vital wayside devices, and a controller which is configured to control the one or more vital wayside devices. The controller is connected to each of the one or more vital switches by means of at least one optical fiber cable and is configured to output one or more light command signals over the at least one optical fiber cable, and each vital switch is configured to switch from an open status to a closed status to provide power and ground to the associated vital wayside device upon receiving at least one corresponding light command signal outputted by the controller for commanding an action of the associated vital wayside device.

Abstract: A railroad track circuit determines occupancy status of a portion of a railroad track, and includes: a track including first and second rails; a transmitter including first and second connection terminals to generate a voltage between connection terminals; and first and second receiver units, each including first and second measurement terminals, the first and second receiver units measuring voltage between first and second measurement terminals. The output connection terminals of the transmitter connect to the respective rails at a first connection location, using first and second cables. The first measurement terminal of the first receiver unit is connected to the first rail at a second connection location, using a third cable and the first measurement terminal of the second receiver unit is connected to the first rail at a third location, using a fourth cable, the second and third locations forming respectively first and second boundaries of the track circuit.

Abstract: The present invention concerns an insulating joint for electrically insulating a pair of adjacent rail sections of a railway track, each rail section extending along a longitudinal axis and defining at least one connecting surface substantially perpendicular to the longitudinal axis and a plurality of lateral surfaces extending along the longitudinal axis. The insulating joint comprises a joint body having substantially the same cross section as the rail sections and defining two contacting surfaces, each contacting surface being intended to be in contact with the connecting surface of one of the rail sections. The joint body is made from an insulating material comprising a reinforcing structure made of metal or carbon fibers, the reinforcing structure being placed inside of the joint body with a distance from the contacting surfaces.

Abstract: A train detection system for a railway track defines a first lateral side and a second lateral side opposite the first lateral side. Two cameras are arranged along the railway track spaced apart from each other. Each camera is placed on either the first lateral side or the second lateral side. The system includes at least one passive target. Each of the passive targets is placed within the field of view of at least one of the cameras and on the opposite lateral side of the railway track with respect to the at least one of the cameras in whose field of view the respective passive target is placed. The system also includes at least one controller adapted to recognise the passive target in the images provided by at least one of the cameras to the controller to determine whether a train is located on the railway track.

Abstract: A wayside communication system for transmitting coded current signals through running rails of a railroad track between wayside control devices. A power line common to the wayside control devices is used as the return path for the current signals. The system features train and broken rail detection. The system allows sending signals long distances since rail to rail current leakage is no longer an issue.
