Abstract
A method for tamping a track in the region of a switch uses a tamping machine mobile on a track. In a first working pass a first branch is brought into desired position and tamped, thereafter the tamping machine travels backward to a point before a branching point, and in a second working pass a second branch is brought into desired position and tamped. During the backward travel, an actual position of the second branch is recorded by a sensor arrangement, particularly relative to the position of the first branch, and correction values for the position of the second branch are calculated based on the recorded actual position. Therefore, the backward travel, which is necessary anyway, is used to determine the position of the second branch, which position changes in the course of the first working pass. A tamping machine for carrying out the method is also provided.
