Abstract
A vehicle-in-spin speed processing system for multiple wheel axle units of a self-powered railway vehicle in which a reasonably accurate vehicle speed reference signal is produced as the wheel axle units are experiencing wheel spin during acceleration of the self-powered railway vehicle so that a minimum amount of error occurs in the output data of speedometers, odometers, and event recorders.
