Apparatus for continuously measuring the position of a moving rail vehicle

摘要

A device for the precise determination of the position of a moving railroad vehicle on a track in a transloader measurement stretch has a multiplicity of switch elements arrayed along one of the rails and actuators positioned to be engaged either by the felly portion of the wheel or the flange portion of the wheel regardless of where the wheel and the track are and in all positions of the wheel on the rail in its sinusoidal movement back and forth as the wheel travels along the rail.
