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.

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 respective pressure sensor to sense pressure supplied to a locomotive brake system and a locomotive and train combination brake system. More particularly, the convertible system includes a microprocessor coupled to each pressure sensor, each respective brake system and a locomotive engine. The microprocessor causes one of an automatic start and automatic stop by sending a respective start up signal and a shut down signal to the locomotive engine.

Abstract: A cable connector housing assembly with an automatic ejector apparatus integral thereto for facilitating disconnection between cable connector housings. A convenient quick-release operating handle is positioned on the connector housing assembly. The handle is used to disconnect the mechanical and electrical connection between first and second electrical connector housings. The connector housing assembly has a novel, pivoting internal cam apparatus which is operatively coupled to the handle, which, when extended, causes the internal cam apparatus to move a captivated V-shaped bar from a first position to a second position, thereby breaking the electrical connection. Internal to the connector housing are rows of locating ribs that facilitate the correct positioning and alignment of the cable end during assembly of the connector.
