A mobile track leveling, lining and tamping machine comprising a ballast tamping assembly mounted on an elongated machine frame and a track lifting and lining unit for correcting the position of the track, the unit being mounted on the machine frame adjacent the ballast tamping assembly and preceding the ballast tamping assembly in the operating direction, and the track lifting and lining unit comprising a two-part tool carrier frame extending in the direction of elongation of the machine frame, a first tool carrier frame part being arranged adjacent the ballast tamping assembly and rearwardly of a second tool carrier frame part in the operating direction, two pairs of flanged wheels supporting the tool carrier frame on the track rails, the two pairs of flanged wheels being rotatable about respective horizontal axes defining a plane and being spaced from each other to form a front pair and a rear pair of flanged wheels on the first tool carrier frame part in the direction of elongation of the machine frame and serving as track lining tools r at least two track lifting tools arranged on the first tool carrier frame part for adjustable engagement with each rail, and a pivot linking the tool carrier frame parts for pivoting about an axis extending perpendicularly to the plane defined by the axes of the flanged wheels. Lifting and lining drives have respective ends linked to the first tool carrier frame part and to the machine frame, and an end of the second tool carrier frame part remote from the pivot is linked to the machine frame.
