Abstract

A method performs compaction of a track ballast bed by use of a tamping unit having two oppositely positioned tamping tools which, actuated with a vibration, are lowered into the track ballast bed during a tamping operation and moved towards one another with a squeezing motion. In this, it is provided that at least one variable vibration parameter is specified in dependence on a duration of penetration into the track ballast bed, until a required penetration depth of the tamping tools has been reached.
