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.

Abstract: In order to measure a speed of a vehicle having an antenna and travelling on a track formed by two rails, first and second discontinuities are detected. The first discontinuity is detected in a current or voltage of a signal generated by an antenna when the vehicle passes a first tuning block of an electric joint. The second discontinuity is detected in a current or voltage of a signal generated by the antenna when the vehicle passes a second tuning block of the electric joint. The detected discontinuities are used to measure the speed of the vehicle travelling on a track divided in track sections separated by electric joints. Each electric joint includes two tuning blocks and a predetermined length of a track section, wherein each of the tuning blocks allows power coupling between adjacent track sections.
