Abstract
An automatic coupling system (10) for a locomotive (11). The automatic coupling system includes a means for detecting a coupling contact and for controlling locomotive systems such as throttle and brakes in response to such contact. The means for detecting contact may be a speed sensor (24), an accelerometer (26), a distance detector (28), and/or a wheel slip detector (30). The automatic coupling system may be integrated with a locomotive remote control system (22) to facilitate the coupling of a locomotive to a railcar (40) when the operator is not located in the locomotive cab.
