ABSTRACT:
A system for verifying the integrity of a train having a predetermined length is provided. The system includes a device for communicating and synchronizing with a detector of a circuit. The detector detects the presence/absence of a train. The device also includes an odometer providing an odometric reference at the start of occupation of the circuit and when the circuit is left by the train, a first processor calculating the distance traveled by the train on the basis of the difference between the two odometric references, a second processor calculating a minimum estimate of the length of the train that is equal to the calculated distance traveled less the algebraic length of the detection circuit and an information mechanism indicating that the train is integral when the calculated length of the train is greater than the predetermined length of the train less the length of a wagon. A method and a computer program product are also provided.
