A track processing machine, in particular an impact wrench machine for track processing, contains at least one handle for manually guiding the track processing machine, a first structural unit with a processing head, which can be driven in rotation for track processing about an axis of rotation, a second structural unit, and a linking unit for mechanically connecting the first structural unit to the second structural unit and for reducing a longitudinal dimension of the track processing machine along the axis of rotation.

A safeguarding system for an emergency fish-plate connector is fastened to a rail base of the rail and has a distance measuring device for supplying a measuring value registering a distance a between the emergency fish-plate connector and the safeguarding system. For transmission of the detected measuring values and of an identifying signalenabling a locally unambiguous correlation of the emergency fish-plate connector with regard to the trackto a control station, the safeguarding system is equipped with a radio device.
