The invention relates to a track maintenance machine for tamping sleepers installed on a ballast bed of a track, comprising a machine frame movable on rail-based running gears, track lifting and lining units for correcting the track geometry as well as two 1-sleeper tamping units arranged one behind the other in the direction of the longitudinal axis of the machine that work independently of one another, with each tamping unit comprising at least four tamping unit segments that work independently of one another, adjustable in height via vertical drives and horizontally shiftable in the transverse direction of the machine via transverse drives, with each tamping unit segment comprising at least one tamping tool carrier, with opposing tamping tools being mounted on the tamping tool carrier and coupled via a vibration drive. It is provided that one of the two tamping units is designed as a turnout tamping unit, that by means of a shifting unit consisting of three transverse guiding units that work independently of one another the associated tamping unit segments are transversely shiftably mounted and can be positioned outwards with respect to the longitudinal axis of the machine in relation to the machine frame or in relation to a satellite frame movable along the longitudinal axis of the machine, and that the other tamping unit is designed as a plain-line tamping unit in such a way that the associated tamping unit segments are transversely shiftably mounted and can be positioned with only one shifting unit. This increases the machine's performance and thus its tamping output when maintaining plain lines and/or turnouts.
