Abstract
For correction of a track position in connection with ballast cleaning, after cleaned ballast has been returned to a track, the actual position of the latter is measured while determining actual position data. Parallel to that, fixed point correction values are determined by a sighting trolley following behind. The actual position data and the fixed point correction values are transmitted to the tamping machine, following behind, and are used for determining correction values for a desired track position to be created by tamping.
