Abstract (en)

The method involves using a measurement system (14) with a measurement line (16) formed by a light beam defined by two reference points (A,B), each formed by a sensing element movable along the track on flanged rollers, whereby the first reference point (A) is in front of the machine and the second (B) between the bogies (2). Relative displacements between the reference points are recorded during a first passage of the machine to form an actual track position graph, from which a desired position graph is derived by forming correction values. The track is raised and packed in the desired position during a second passage by recording the relative displacements of the reference points according to the correction values. An Independent claim is also included for an arrangement for packing a railway track.

Abstract (de)

In einem Verfahren zum Unterstopfen eines Gleises (6) werden in einer ersten Maschinenvorfahrt Relativverschiebungen zwischen zwei Meß-Bezugspunkten (A,B) unter Bildung einer Ist-Lägekurve des Gleises (6) registriert. Anschließend wird aus der Ist-Lagekurve unter Bildung von Korrekturwerten (34) eine Soll-Lagekurve des Gleises (6) errechnet. In einer zweiten Maschinenvorfahrt erfolgt unter Registrierung der Relativverschiebungen zwischen den beiden Meß-Bezugspunkten (A,B) entsprechend den ermittelten Korrekturwerten eine Anhebung und Unterstopfung des Gleises in die Soll-Lage. <IMAGE>
