1. A system of controller modules allowing to remotely control a train having a first locomotive and a second locomotive separated from one another by at least one car, said system of controller modules comprising:

  • a) a first controller module associated to the first locomotive;

    b) a second controller module associated to the second locomotive;

    c) one of said controller modules having a lead operational status;

    d) the other of said controller modules having a trail operational status;

    e) the controller module having the lead operational status including;

    I. an input for receiving a master control signal for signaling the train to move in a desired direction;

    II. an output to release in response to the master control signal a first local command signal operative to cause displacement of the locomotive associated with the controller module having the lead operational status;

    f) the controller module having the trail operational status including an output, the controller module having a lead operational status being further operative to transmit to the controller module having a trail operational status a local control signal derived from the master control signal, the controller module having the trail operational status is responsive to said local control signal to generate a second command signal operative to cause displacement of the locomotive associated to the controller module having a trail operational status, the movement of the locomotive associated with the controller module having the lead operational status and the movement of the locomotive associated with the controller module having the trail operational status being such as to cause displacement of the train in the desired direction.
