Abstract: A method of correcting the position of a railroad track composed of laterally adjacent track sections connected by branch tracks comprises the steps of measuring the position of each individual track section relative to an absolute reference system common to both track sections and registering high points, thereby forming actual position curves, while parallel thereto actual versines of the track position are detected by means of a further, machine-specific reference system. A target position curve is then generated which is common to the measured track sections and 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. Track correction values are determined by obtaining the difference between the actual position curve of a respective track section and the common target position curve.

Abstract: A tamping tool assembly comprises two pairs of tamping tools succeeding each other in the direction of elongation of a railroad track, two of the tamping tools of the pairs being adjacent each other and the other two tamping tools of the pairs being remote from each other.
