Abstract: This automatic vehicle control apparatus comprises a first image sensor positioned on a vehicle, able to capture a first global image of a first scene, including an area in front of the vehicle, in a first field of view of said first image sensor; a track occupancy detector for receiving the first global image and deducing therefrom a track occupancy of the vehicle among at least two set of parallel tracks positioned in front of the vehicle; a distinguishable object disposed in the first field of view; and a proper functioning checking apparatus configured for searching, in the first global image, a first specific image of the distinguishable object, and for generating an alert signal in case the first specific image is not found in the first global image.

Abstract: The invention concerns a method for determining the location of a railway vehicle comprising a first navigation module determining a regular resolution position of the railway vehicle with a first accuracy measurement and a second navigation module determining a high resolution position of the railway vehicle with a second accuracy measurement, using the received signals. The method comprises the steps of determining a first confidence area around the regular resolution position, based on the first accuracy measurement, of determining a second confidence area around the high precision position, based on the second accuracy measurement, and of assigning a weight of confidence to the knowing of the actual location of the railway vehicle, by analyzing the overlay of the first and the second confidence areas and the first and the second accuracy measurements.

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: System for determining train information relative to a train moving along a railway track having a pressure measuring device placed along the railway track and arranged to measure the speed of an airflow generated by the train when moving on the railway track, and to generate a speed signal; and a controller arranged to receive said speed signal and to determine train information relative to the train in function of said speed signal.

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.
