摘要：The invention relates to an arrangement and method for measuring andcorrecting the line of a track. The method comprises forming an optical reference beambetween an emitter on an emitter bogie and a position- sensitive receiver on a measuringand correcting car, moving the measuring and correcting car for a measurement intervalin sequences of a desired length towards the emitter bogie, monitoring the movement ofthe hitting point of the optical beam by the position- sensitive receiver, measuring lateralinclination of the track, positioning the position- sensitive receiver in relation to the trackbetween the sequences of moving, and measuring the instantaneous values of theposition of the hitting point of the optical beam and the inclination of the track, and usingthe measurement data for the shifting operations directed to the track. The methodfurther comprises measuring the position of the measuring and correcting car in thelongitudinal direction of the track, which measuring is combined with position- sensitiveoptical measuring effected substantially without clearance in relation to the track formeasuring the three-dimensional coordinates of the track substantially at the point ofthe track to which corrective shifting operations are directed.
