ABSTRACT:
The invention is a process and a device for measuring and registering the geometric state of a track in the course of alignment of the track with an aligning machine. The distance between a point on the already aligned track and a straight line defined by two points, one of which is on the already aligned track and one of which is on the part of the track to be aligned, is measured, and the value is registered after each alignment operation.
