Abstract
A method for the correction of vertical position error of a track by a track tamping machine and a dynamic track stabilizer. Starting from a registered actual position, an over-lift value is prescribed for a treated track location with which the track is lifted into a preliminary over-lift track position and tamped. The track is subsequently lowered by dynamic stabilization into a resulting final track position. In this, a smoothed actual position course is formed from a course of the actual track position, wherein an over-lift value is prescribed for the treated track location in dependence of the course of the actual track position with regard to the smoothed actual position course. In this way, only short-wave track faults are treated with an over-lift value.
Claims12
A method of correcting vertical position faults of a track, the method comprising:
- measuring an actual track position;
- forming a smoothed actual position course from a course of the actual track position;
- starting from the actual track position, prescribing an over-lift value for a given track location that is being treated, the over-lift value being dependent on the course of the actual track position relative to the smoothed actual position course;
- lifting the track into a preliminary over-lift track position defined by the over-lift value of the given track location and tamping the track with a track tamping machine;
- and
- subsequently lowering the track by dynamic stabilization with a dynamic track stabilizer into a resulting final track position.
