Abstract of the Disclosure The tamping head on a mobile track tamper includes a pair of rigid tamping tool units each consisting of a T-shaped holder whose vertical arm is mounted on a vertically movable carrier and whose transverse arms each have a stationary tamping tool mounted therein. The tamping tool units are vibrated by an eccenter shaft and reciprocated by hydraulically operated piston rods linked to the eccenter shaft and to the vertical arms of the holders, respectively. A housing defining an oil sump in the lower portion thereof is mounted on the carrier and holds the eccenter shaft, and bearings which rotatably mount the eccenter shaft in the housing and link the hydraulic drives to the eccenter shaft being lubricated by the oil from the sump.
