Abstract
An apparatus for monitoring the motion of a railroad train includes an on-board unit which computes the speed, acceleration/deceleration, and distance traveled events of the train and stores such computed data for retention by a non-volatile memory after a power interruption or outage occurs. The apparatus also includes a portable unit to which the on-board unit, or the data retaining memory thereof, can be connected for conducting data transfers from the on-board unit memory to the portable unit. Once stored in the portable unit, the information can be formated and displayed as a history of the train operation for management and maintenance personnel, for example.
