Abstract
An apparatus for determining the direction of locomotive travel while in dynamic braking is disclosed. This direction of travel is derived from current sensors associated with the locomotive traction motors. When in the dynamic braking mode, current flows through the current sensors in a first direction when a train is traveling in the first direction and reverses the direction of flow when the train is traveling in a second direction.
