[origin: EP0195882A1] 1. A track tamping machine (1) comprising a vertically displaceable plain-track tamping unit (15) for tamping the ballast beneath two immediately adjacent sleepers (4), comprising - for both sides (19, 20) of a rail (3) - two pairs (21, 22) of tamping tools arranged one behind the other longitudinally of the machine which consist of vibratable doubletine tamping tools (24-27) squeezable towards one another and designed to penetrate into the ballast bed on both longitudinal sides of the sleepers and on both sides of a rail, the inner tamping tools (25, 26) on the mutually opposite sides of the pairs (21, 22) of tamping tools being designed to penetrate into the same sleeper crib (30) between two immediately adjacent sleepers (4) and all the pairs (21, 22) of tamping tools with their tamping tools (24-27) connected by squeezing drives (32) being arranged on a common tool carrying frame (12) and being connected to a common vertical displacement and vibration drive (33, 34), characterized in that at least the frontmost and rearmost tamping tools (24, 27) - longitudinally of the machine - of two pairs (21, 22) of tamping tools - adjacent one another transversely of the track - of the two-sleeper tamping unit (15) each comprise, for displacement independently of the other tamping tools, a holder (35) carrying a double tine (28) which is mounted on the corresponding tamping tool to pivot about an axis (36) extending longitudinally of the machine and are each connected to a lateral displacement drive (37) arranged on the tamping tool (24, 27).
