PROCESS AND APPARATUS FOR MEASURING THE GEOMETRIC STATE OF A RAILWAY TRACK DURING CORRECTION THEREOF

摘要

ABSTRACT OF THE DISCLOSUREThe invention is a process and a device for measuring and registeringthe geometric state of a track in the course of alignment of the track with analigning machine. The distance between a point on the already aligned trackand a straight line defined by two points, one of which is on the alreadyaligned track and one of which is on the part of the track to be aligned, ismeasured, and the value is registered after each alignment operation.
