A tamping machine (4) for simultaneously tamping a plurality of sleepers (22) of a track (2) comprises a machine frame (10) supported on on-track undercarriages (11), two multiple tamping units (18,19) designed for simultaneously tamping at least two sleepers (22) respectively and arranged one following another in the longitudinal direction of the machine, a track lifting and lining unit (27), and also a reference system (30) for performing track geometry corrections. A sleeper spacing (a) is defined by the spacing apart of two tamping tines (20) of each multiple tamping unit (18,19), the said tamping tines being adjacent in the longitudinal direction of the machine - located in their starting position for tamping - and squeezable together by means of a squeeze drive (24). The two tamping tines (20) of the two multiple tamping units (18,19), which are adjacent to one another in the longitudinal direction of the machine, are spaced apart from one another by a distance equivalent to a sleeper spacing (a).
