A tamping device for track tamping machinery includes multiple pairs of tamping tools mounted on a support, the support being height-adjustably guided within a frame of the tamping device. The pickaxe ends of the tamping tool pairs are driven in opposite directions by linear oscillating actuators and are hydraulically fed relative to each other. At least two tamping devices are arranged along a longitudinal axis of the tamping device parallel to the longitudinal direction of the track tamping machinery. At least two tamping devices are arranged side-by-side transversely to the longitudinal axis of the tamping device. Two spaced-apart planes perpendicular to the longitudinal axis of the tamping device on either side of the support form a working space. A rocker arm and the tamping tool pairs trace a motion trajectory within the working space via the pickaxe ends during feeding motion. The envelope of this motion trajectory lies only within the working space. The linear oscillating actuators of the tamping device are arranged overlapping each other in an oscillation plane extending transversely to the plane and are at least nearly parallel to each other and inclined relative to the longitudinal axis of the tamping device.
