Abstract
A train vehicle zero speed sensing apparatus is provided for operation with a pair of tachometers coupled to the drive mechanism of a train vehicle, such that zero speed or an equivalent zero speed of the vehicle is sensed, and any single failure is detectable and will not yield a false zero speed indication.
