A tamping assembly (1) for track tamping machines consists of a total of four tamping units (3) arranged side by side in the transverse direction of the track and transversely displaceable independently of one another by means of drives (2), each having an auxiliary frame (5) with a tool carrier (7) which is mounted for vertical adjustment and two vibratable and squeezable tamping tools (9) mounted thereon and lying opposite one another in the longitudinal direction of the machine. Each tamping tool (9) is connected to a tamping tine (13) which may be pivoted by means of a pivot drive (18) about a swivel axis (15) extending in the longitudinal direction of the machine. The inner tamping tine (14) of each tamping unit (3) which is adjacent to the auxiliary frame (5) is rigidly connected to the tamping tool (9), while the outer tamping tine (13) adjacent to it in the transverse direction of the machine is pivotable about the swivel axis (15) between two end positions defined by stops (16, 17, 24, 25) from a first tamping position (23) immediately adjacent to the inner tamping tine (14) into a second tamping position (26) - suitable for the immersion of the two tamping tines (13, 14) on either side of a rail (4).
