Abstract:
1. A machine for leveling and alignment of a section of ballastless railway track having two rails joined through fasteners to connecting elements, comprising: a structure comprising a main body and a secondary body coupled to the main body and movable laterally relative to the main body, a measuring system, comprising a plurality of tilt sensors for sensing a relative position of the track in real-time, and a total station for acquiring data relating to absolute position of the track, such that an actual position of the track is determined in real time; a control system comprising a processor having software for processing position of the track acquired by the tilt sensor and the total station, comparing the actual position of the track with a desired final track position, obtaining as a result the difference between the desired final track position and the actual track position, and determining the lateral movement of the secondary body on the main body needed to achieve the desired final track position, such that the processor controls the hydraulic lift cylinders and the relaying hydraulic cylinders such that the machine carries out the required movements.
