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.
