Railroad track position correcting method

摘要

The method for correcting the level of a track built from rails and sleepers comprises independently measuring the left and right rail of a section of track to determine and record an actual height level (15) using a computing and control unit. Electronic smoothing of defects outside an acceptable tolerance is then used to produce a height target (19). A start (S) and end point (E) are then established to mark out the section of track whose height is to be corrected (24). A machine for feeding ballast to the track is then positioned at the start. The rail supporting surface is then adjusted to the level of the previous section which does not require correcting (22). Height correction is then carried out independently for each rail to conform with the target.
