Abstract
A system for verifying the integrity of a train having a predetermined length including: a device for communicating and synchronising with a detector of a circuit, detecting the presence/absence of a train, 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 travelled 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 travelled less the algebraic length of the detection circuit, 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.
