  • Patent number: 4955304
    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.
