Abstract (en)
[origin: WO2022268566A1] Method for correcting vertical position faults of a track (4) after a lifting-tamping process, comprising a stabilization process which is carried out by means of a dynamic track stabilizer (1) and during which a stabilization assembly (22) acts on the track (4) at an working point (22) which moves forwards in a working direction (7), wherein, before the lifting-tamping process, track position data relating to the unworked track (4) is recorded and wherein, after the lifting-tamping process, track position data relating to the underfilled track (4) are recorded at a measurement point (10) which is located upstream of the stabilization assembly (22) in the working direction (7). In the process, additional track position data relating to the stabilized track (4) are recorded at a post-measurement point (21) which is located downstream of the stabilization assembly (22) in the working direction (7), wherein the dynamic track stabilizer (1) is actuated during the stabilization process depending on track position data relating to the unworked and the underfilled track (4) at the working point (22) and on track position data relating to the stabilized track (4) at the post-measurement point (21). The additional post-measurement of the track position after the stabilization process allows exact control of the dynamic track stabilizer (1).
