Abstract:
1. A locomotive assembly comprising: a power bus; a locomotive comprising: an operator interface comprising at least one equipment control input; a primary power unit coupled to the power bus; and a legacy locomotive controller electrically coupled to the operator interface, the legacy locomotive controller programmed to: convert an input received from the at least one equipment control input into a power unit control signal indicating an amount of locomotive power; and transmit the power unit control signal to the primary power unit; a sensor system electrically coupled to the legacy locomotive controller; and an intercept locomotive controller programmed to: intercept the power unit control signal transmitted from the legacy locomotive controller to the primary power unit; modify the power unit control signal; and transmit the modified power unit control signal to the primary power unit; intercept a sensor signal transmitted from the sensor system to the legacy locomotive controller; modify the sensor signal to match an expected sensor value indicating that the primary power unit is producing the amount of locomotive power; and transmit the modified sensor signal to the legacy locomotive controller; and wherein the intercept locomotive controller is electrically coupled between the legacy locomotive controller and the primary power unit.
