ABSTRACT:
Measurement of a track position is carried out in successive measurement sections (15), wherein the relative track position is registered in each case with the aid of a long chord (17), formed by a laser beam (16), which serves as reference line of a measuring system (9). During this; an angle enclosed by the two long chords (17) of two successive measurement sections (15) is measured in order to thereby obtain a spatial curve reproducing the actual position of the track.
