A track maintenance machine for compaction of ballast under sleepers of a track includes a machine frame movable by undercarriages on the track and a tamping unit which includes an electric vibration drive for vibratory actuation of tamping tools. An electric intermediate circuit has an electric energy store or storage device. An electric machine is associated with at least one undercarriage and coupled for generator operation to the intermediate circuit. The electric vibration drive is coupled to the intermediate circuit for supply. In this way, braking energy is used in an optimal manner for supplying the vibration drive. A method for operation of a track maintenance machine is also provided.

A track maintenance machine includes a combustion engine mechanically connected by a drive shaft to an electric generator/motor unit. The electric generator/motor unit is connected by a mechanical drive unit to a hydraulic pump. A power accumulator is connected by an electrical supply line to the generator/motor unit and to drives which can be actuated electrically. It is thus possible to mainly electrically supply all of the drives.
