ABSTRACT A track tamping machine particularly a track tamping, levelling and lining machine is equipped with at least one tamping unit including a carrier which carries tamping tools. The tamping unit is vertically movable on a sub-frame by means of a hydraulic cylinder and is fastened thereto. The sub-frame itself is suspended from the chassis of the tamping machine pivotably like a pendulum. The sub-frame has two guide columns guiding the tool carrier through its vertical motion and, at its lower end guide rollers which revolve on rail for the purpose of centering the tamping unit. A control cylinder is activated for the purpose of swinging the tamping unit in such a way that while the machine is uniformly moving forward at constant speed, the tamping tools can perform their tamping function at subsequent ties.
