This comprises a track stabiliser (12) designed for actuation and vertical displacement by drives with roller tools (14) designed for application to the insides of the rails by spreading drives and for vibration by vibrators. A levelling reference system (16) comprises a reference basis (17). A measuring wheel axle (19) with a height transducer (18) is provided, being arranged off-centre in relation to two end points of the reference basis and behind the track stabiliser in the working direction of the machine.
