ABSTRACT:
A convertible system is provided for controlling automatic starts and automatic stops of a locomotive engine. The convertible system is switchable between a yard mode and a road mode based upon respectively using the locomotive in one of a yard region and road region. The convertible system includes a pressure sensor to sense pressure supplied to a brake system. More particularly, the convertible system includes a microprocessor coupled to the pressure sensor. The microprocessor causes one of an automatic start and automatic stop by sending a respective start up signal or a shut down signal to the locomotive engine, based on comparing the pressure supplied to the brake system with a stored pressure threshold for each of the yard mode and road mode.
