An electronic control system for automatically controlling the locomotive units of a multiple unit locomotive consist in a manner to maintain a selected speed of the consist with minimum fuel consumption. The control system includes a microprocessor and related hardware for each unit in the consist. Control and acknowledgement signals are transmitted among the locomotive units along a single train line wire to vary the output power of each unit among full power, half power and idle speed settings while maintaining the consist at the desired set speed. The hardware is arranged to direct the control and acknowledgement signals to the proper locomotive units while transmitting in both directions along the train line wire. The software for the microprocessors takes into account the acceleration and deceleration of the consist in adjusting the power output of the locomotive units.

A control device for controlling a multiple unit locomotive system having a plurality of individual locomotive units each having high and low throttle positions and a plurality of discrete throttle positions between the high and low positions for normal operation of the locomotive system, said control device comprising: means for setting a predetermined set speed of the locomotive system; sensing means for sensing the actual speed of the locomotive system; and control means operable in response to the presence of a differential between the actual and set speeds to automatically and sequentially vary the throttle positions of the individual locomotive units between the high and low throttle settings thereof in a manner to effect substantial conformity of the actual speed with the set speed.
