Abstract

For tamping a track, tamping tines are squeezed towards one another in pairs by a squeezing cylinder. A vibration is superimposed on a linear lift motion of a squeezing piston movable in the squeezing cylinder. The vibration is generated by a vibration piston which is arranged in the squeezing cylinder and which is movable independently of the squeezing piston.
