The invention refers to a machine and a method used to level, align and stabilise the track and compact the ballast bed, producing controlled lifting, so that the load used in the settlement of the rail in its theoretical position falls within the established range, working in an uninterrupted manner. The machine is constituted by two bogies with traction capacity, and front, back and centre control cabins and a rear and frontal measuring tensioner trolleys. The machine has an additional lifting unit whose relative movement with the rest of the machine in controlled by total longitudinal cylinder. The alignment cylinders generate a transversal movement to cause track alignment. Behind this unit according to the direction of work a stabilising unit is situated which consists of two stabilising trolleys. The ground-penetrating radar is situated at the machine front.
