Abstract:
A method of correcting the position of a railroad track composed of laterally adjacent track sections connected by branch tracks, which comprises the steps of:(a) measuring the position of each individual track section relative to an absolute reference system common to said track sections while registering high points, thereby forming actual position curves, and parallel thereto(b) detecting actual versines of the track position by means of a further, machine-specific reference system,(c) generating a target position curve, common to the measured track sections, which is composed of the registered high points of the individual measured track sections and design sections, located between said high points, which smoothen the trace of the actual position curves,(d) determining track correction values by obtaining the difference between the actual position curve of a respective track section and the common target position curve, and(e) implementing the track position correction while synchronously lifting and/or laterally shifting the measured adjacent track sections according to the determined track correction values.
