Abstract
An apparatus for determining and encoding the position of a control handle on a control stand of a locomotive or other railway transit vehicle utilizing a rotational, absolute encoder rigidly mounted adjacent to the axle to which the control handle is attached for pivotal motion, wherein a drive transfer means interconnecting the control handle and/or axle with encoder has a driving ratio that will permit full partial rotation of the control handle, which is typically less than 90 degrees, to rotate the encoder axle through a significantly greater rotational angle not exceeding 360 degrees, for the purpose of making fuller use of the sensitivity and resolution range of the encoder.
