Abstract (en)

[origin: WO2019007621A1] Disclosed is a method for compacting a track ballast bed (2) by means of a tamping unit (1) comprising two opposite tamping tools (6) which, during a tamping process, are lowered into the track ballast bed (2) while being made to vibrate and are moved towards one another using a lateral movement. According to the invention, at least one variable vibration parameter (16, 23) is predefined in accordance with a penetration time (13) into the track ballast bed (2) until a required penetration depth of the tamping tools (6) has been reached.
