The unit includes a tamping tool carrier, respective pairs of tamping tools mounted on the carrier for pivotal movement in the direction of the track independent of each other, the pairs of tamping tools being respectively arranged on the field side and the gage side of the respective track rail for immersion in the ballast adjacent a point of intersection of the tie and rail where the track is supported on the ballast, a single hydraulic reciprocating drive connecting the tamping tools of each pair for pivoting the tamping tools of the pair independently of each other and asynchronously towards and away from each other in this direction, a single vibrating drive connected to the tamping tools of each pair for vibrating the tools. The tamping tools of each pair are centered by a separate elastic force-transmitting element supported on the carrier and biasing a respective one of the tamping tools in the direction of reciprocation thereof.
