ABSTRACT:
An apparatus and method is provided for measuring the wear in the cross-sectional profile of a railroad rail. A carriage is adapted for travel along the length of the rail and includes means for moving transversely with respect to its direction of travel in response to wear in the railhead of the rail. Distance sensors fixedly mounted to the carriage sense the changes in distances from the carriage to the rail as the carriage moves in a direction transverse to the direction of travel. The sensors relate the changes in these distances to wear in the top and gauge sides of the railhead.
