1. A communication apparatus for transmitting multicomponent input signals over a common carrier from a plurality of control stations to at least one remotely controlled locomotive having a unique call-on address means, responsive only to input signals having the same call-on address component and each control station includes transmitting means for selectively transmitting control signal components for governing the operation of the locomotive and the call-on address wherein the improvement comprises:

  • a. means at each control point coupled to the transmitting means for providing a unique assignment address component to the input signal indicative of the associated control point;

    b. address-receiving means on the locomotive having multiple channels selectively responsive to the associated assignment address for providing a manifestation of the identity of the source of said input signals;

    c. assignment address command means for providing a unique address command component to the input signal; and

    d. switching means governing the inputs to the address-receiving means and the call-on address means responsive to the unique address command components of the input signals for coupling the appropriate address-receiving means channel associated with the control station and subsequently decoupling the call-on address means so that only input signals from the first control station to transmit valid input signals are accepted by the address-receiving means thereby locking out all input signals from the other control points, and assuring exclusive control of the locomotive by the engaged control point at any one time.
