Abstract
Ballast (3) located underneath of sleepers of a track is compacted by immersion and squeezing of compacting tools (7) set in vibrations. The vibrations introduced into the ballast (3) during the compacting process are registered as a measure of the ballast compaction. Thus, it is possible to obtain a homogenously compacted track even in the event of different ballast characteristics.

A method for compaction of the ballast bed of a track by means of a compacting tool (7) being set in vibrations, wherein the vibrations introduced into the ballast during the compacting process are registered as a measure for the ballast compaction.
A tamping unit for compacting ballast located underneath a track, having tamping levers (5), pivotable about a pivot axis (4), which are connected at a lower end (6) in each case to a compacting tool (7) provided for immersion into the ballast (3) and, at an upper end (8), to a squeezing drive (9), wherein an acceleration sensor (13) connected to a control unit (12) is arranged at the tamping lever (5) and/or on the compacting tool (7).
