A machine (1) for treating a track bed comprises a machine frame, mobile on a track (10) by means of on-track undercarriages (8), which consists of thre e frame parts (3,4,5) articulatedly connected to one another by frame joints (6,7). The central frame part (5) is connected to two caterpillar-tracked undercarriages (12) spaced from one another in the transverse direction of the machine and vertically adjustable by means of drives (13). With this, by supporting the caterpillar-tracked undercarriages (12) on an earth formation (16), a construction gap (17) of the track can be extended for a formation rehabilitation.
