Abstract:
The present invention is directed to a controller having a power handle to control both the propulsion function and the braking function, and a reverser handle to control the direction in which the locomotive travels. The power handle is operatively connected to a propulsion and brake control device which controls the propulsion and braking functions of the locomotive, while the reverser handle is operatively connected to a reverser control device which controls direction of travel. The propulsion and brake control device preferably includes a propulsion controller to control the propulsion function of the locomotive, a braking controller to control the braking function and an indexing mechanism to independently operate either the propulsion controller or the braking controller. The indexing mechanism preferably includes a drive gear operatively connected to the propulsion controller via a first lost motion device which controls the propulsion function when the power handle is moved in a first direction and to the braking controller via a second lost motion device which controls the braking function when the power handle is moved in a second direction. In order to insure mutually exclusive movement of either the propulsion controller or the braking controller, a throttle-brake interlock is preferably provided.
