  • Patent number: 11724724
    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.

  • Patent number: 11124211
    Abstract: A method for locating a railway vehicle includes: measuring an acoustic signature of a railway vehicle passing over a railway switch for switching between a first railway track and a second railway track diverging from the first railway track, using a distributed acoustic sensing apparatus including an optical fiber sensor placed along the railway switch; analyzing the measured acoustic signature, using an electronic processing unit, by identifying, in the measured acoustic signature, vibration patterns representative of track geometry and/or track curvature; and determining which of the first railway track or the second railway track is occupied by the railway vehicle, using the electronic processing unit, based on the identified vibration patterns.

  • Patent number: 11001974
    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.

  • Patent number: 10946883
    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.

  • Patent number: 10614708
    Abstract: A train detection system for a railway track section placed on a track bed, the track section having two rails, the train detection system comprising at least one cable, the cable being placed across the two rails, a transmitter connected to the cable and configured to emit an emitted signal into the at least one cable, a receiver connected to the cable and configured to receive a received signal related to the emitted signal having passed through the cable, and capable of determining, according to the received signal, between an unoccupied state where no railway vehicle is present on the track section, and an occupied state where the track section is occupied by a railway vehicle. The cable is buried under the track bed.

  • Patent number: 10293840
    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.
