Abstract
Apparatus for determining and encoding the position of a reverser control handle on a control stand of a locomotive or other railway transit vehicle of the type having a reverser control handle attached to an axle partially rotatable through a defined angle and including a pair of stationary signal transmitting sensor means, and a pair of sensor activators secured to the axle adapted for partial rotation with the axle, whereby one each of the pair of sensor activators are positioned proximate to one each of the signal transmitting sensor means, so that any partial rotation of the axle in one given will be sensed by one such signal transmitting sensor means to provide a second signal, and partial rotation of the axle in the opposite direction will be sensed by the other signal transmitting sensor means to provide a second signal.
