Abstract: Controlling a level crossing of a railway track by providing a train having an onboard processor communicating with a wayside processor associated to a level crossing, said train having a forward end and a rear end; moving the train forward along the railway track lowering down gates of the level crossing when train is at a predetermined distance upon detection of the train approaching the level crossing; when the forward end passes over a first reference point defining the beginning of an island area of the level crossing, sending a first message from the onboard safety processor towards the wayside processor informing that the train is approaching the level crossing; maintaining down gates; when the rear end passes over a second reference point defining the end of the island area, sending a second message from the onboard safety processor to the wayside processor informing that the train has left the level crossing; and lifting the gates.

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 method is for determining a status of a track section of a railroad. Each end of the track section is connected to a respective detector. One of the two detectors transmits a current along the rails of the track section towards the other detector and receives a current transmitted along the rails of the track section from the other detector. The track section is further equipped with a computer in communication with the two detectors. The computer calculates an instant value of the status of the track section as a function of an instant vector based on a measure of an intensity of the current transmitted by a first of the detectors as measured by the first detector (Txl1), a measure of an intensity of the current received by the first detector as measured by the first detector (Rxl1) and a measure of an intensity of the current transmitted by the second detector as measured by the second detector (Txl2).
