This system includes a ground ATC and an on board ATC, which is switched from an 'active' mode toward a 'standby' mode and vice versa by a wake-up unit. In the &#x201c;standby&#x201d; mode, only the following components remain powered: odometry device; a main computer; a radio communication device between the on board ATC and the ground ATC; the wake-up unit. The main computer is programmed so as, in the &#x201c;standby&#x201d; mode, to verify that the movement of the train measured by the odometry device from the switching from the &#x201c;active&#x201d; mode to the &#x201c;standby&#x201d; mode is zero and, in the affirmative, to send the ground ATC an instantaneous position of the train using the radio communication device.

Automatic train control system and corresponding method

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 () an origin zone and an output signal; drawing () a pseudo-route on the successive zones between the origin zone and the output signal; opening () the pseudo-route by associating a sub-route with each zone, corresponding to the reservation of said zone for said train; informing () the train that it must circulate in the opposite direction; determining () a movement authorization for the train from sub-routes that are open and a list of obstacles that is updated regularly; sending () the movement authorization to the train, the determination () and transmission () steps being iterated until the train crosses the output signal.
