Each track section (3,4) is measured by recording the high points (19) in relation to an absolute reference system (17), with the forming of actual position curves (18). Parallel to this, by a machine reference system (9), actual upright heights (27) are determined. A common desired position curve (20) is formed for the measured sections (3,4), which from the high points (19) and laid between these, the curve course of the actual position curves (18) are assembled with smoothed design sections (21). The track correction values (22) are determined by forming a difference between the actual curve (18) of the respective branch section and the common desired curve (20). The track position correction is carried out with synchronous lifting and/or lateral shifting of measured and adjacent track sections (3, 4) corresponding to the determined track correction values (22). |
