ABSTRACT:
An improved technique for correcting errors in track, for example errors in alignment and cross-level. A record of the actual geometric condition of a section of track is obtained by running a recording car operating at a predetermined speed and axle loading over the track. A record which may be on magnetic tape is thus obtained for one or more parameters such as alignment. In some cases this record may be used directly to derive electrical error signals which control a track moving device which moves the track in a direction to remove the error. Where the parameter of interest is alignment and the section of track is curved, a desired geometric condition has to be obtained for comparison with the actual geometric condition to derive the electrical error signals. One way of obtaining the desired geometric condition is to process the record to achieve a running average taken over ten or so consecutive sample points.
