Lateral leveling technology at setting railway tracks in the design position

The automation of the lateral leveling method at constructing and repairing railways is covered in the article. The essence of this method is comparing the design distances between the axes of the repaired and the adjacent track having a given step (leveling plot) with the actual data obtained from the leveling rail and using the control system of the lifting-and-leveling device to offset the path to the design value. At the same time, the disadvantages of this method are obvious – this is copying the bumps of the adjacent track to that being at repair. Automation eliminates the disadvantages of the existing technology for setting the railway track into the design position using lateral leveling. The authors show the schematic diagram and device of the automated control system ACS-3D for setting the path into the design position, created with considering the exclusion of the "human factor" influence, a high automation degree and minimizing the cost of creating a digital project, as well as eliminating the need for mobile communications and that of high-precision measurements by global satellite navigation systems.
