ABSTRACT OF THE DISCLOSURE A mobile track correction machine, which comprises a vertically adjustable tool carrier guided along the track, track lining and lifting tools on the carrier, hydraulic lining and lifting jacks linking the carrier to the machine frame and a control circuit controlling actuation of the jacks and including a switch operable to terminate actuation of the lifting jack, has a safe- ty arrangement for terminating the actuation on disengage- ment of the tool carrier from the track. The safety ar- rangement includes an electronic, inductive proximity fuse affixed to the tool carrier and mounted above, and at a nominal distance from the running face of the rail engageable by a respective lifting tool, the proximity fuse being connected to the switch and capable of trans- mitting an operating signal thereto without touching the running face when the distance between the proximity fuse and the running face is more than the nominal distance.
