Abstract
A machine for track maintenance is manually displaceable on a track. The machine has a work module with a handle, a working tool powered by a drive and a machine frame configured to be guided on a rail of the track. The work module is detachably connected to an energy module and the energy module has an electrical energy store and output contacts. The output contacts are detachably connected to input contacts of the work module. The work module has as the drive an electric motor supplied with electrical energy from the energy store. This solution results in a high degree of overall efficiency because the energy available in the energy store serves for the largest part for covering performance peaks.
