Remote locomotive spotter control
First Claim
1. A remote spotter for a self driven vehicle having a traction motor for driving the vehicle, brakes for stopping the vehicle and an on board secondary power source separate from a primary source of traction motor power, said spotter comprising:
- auxiliary drive means for connecting the secondary power source to the traction motor for driving the vehicle,auxiliary brake means for applying the brakes to stop the vehicle, anda remote unit connectable with said vehicle auxiliary drive and brake means and normally operative upon such connection to actuate the auxiliary brake means to apply the brakes, said remote unit having first and second manually actuated self released controls, said first control being normally operative upon actuation to release the brakes and said second control being normally operative upon actuation to actuate the auxiliary drive means to move the vehicle.

Abstract
A remote locomotive spotter control having a plug in remote unit to control braking and battery power to one or more traction motors for moving the locomotive from an outside location. The control system provides automatic bell operation when the brakes are released and brake application whenever the remote brake control is released. Additional features prevent operation of the spotter control until the locomotive independent brake has been set and whenever the main reservoir pressure is too low for repeated brake application. Damage to the battery through inadvertent connection to the main generator is also prevented.
