Abstract
A tamping machine for tamping a track has a lifting-lining unit, connected to lifting and lining drives, for shifting the track into a target position. A vibration generator, which can be set to vibrate, is disposed on the lifting-lining unit. It is thereby possible to tamp a track section in a first working pass and to lower it in a controlled way in an immediately following second working pass with constant impact of vertical load and vibration. Thereafter, the track can be traveled upon with normal speed entirely unhindered.
