Abstract: When an event prevents a train from moving along a route in a nominal direction, this method makes it possible to cause it to circulate in an opposite direction by: selecting (120) an origin zone and an output signal; drawing (130) a pseudo-route on the successive zones between the origin zone and the output signal; opening (140) the pseudo-route by associating a sub-route with each zone, corresponding to the reservation of said zone for said train; informing (150) the train that it must circulate in the opposite direction; determining (160) a movement authorization for the train from sub-routes that are open and a list of obstacles that is updated regularly; sending (180) the movement authorization to the train, the determination (160) and transmission (170) steps being iterated until the train crosses the output signal.

Abstract: Controlling a level crossing includes one or more transceivers located in proximity of a level crossing area on a first side of a railway track; corresponding passive reflective targets located in proximity of the level crossing area on a second side of the railway track opposite to the first side where each transceiver is located and a control unit connected to each transceiver. Each target is arranged to receive RF signals coming from each transceiver and to send back corresponding reflected signals. Each transceiver is arranged to elaborate said reflected signals to calculate predetermined parameters values. Also, the control unit is arranged to acquire said parameters values from each transceiver and to elaborate them to detect the presence of a train in an area around the level crossing area and, in case of presence of said train, to send a warning message and/or close bars of the level crossing.

Abstract: A method is for maintenance of a ground-level power supply for a transport vehicle. The device includes: a power supply rail, a detector of spatial coordinates of a vehicle; and a power supply shoe. The device and the shoe equip the same vehicle. The supply shoe includes a vibration sensor. The method includes measuring vibrations of the shoe and simultaneously detecting spatial coordinates of the vehicle during the movement of the vehicle along the rail, followed by comparing measured vibrations of the shoe with a threshold value, and determining spatial coordinates corresponding to vibrations above the threshold value.
