1. measure the method for each rail cross section of railway or gauge in contactless mode for one kind, it is characterized in that this method comprises the following steps:

  • A) utilize one be positioned at rail (6) top, that vertically move along track continuously and one perpendicular to track longitudinally the distance measuring sensor (16) that scans of detection plane (20) survey every one steel rail (6),B) rail tested point (25) that record is easily caused danger in a rho theta system, that the track switch geometric figure is had decisive significance is as measured value,C) polar coordinates with measured value is converted into rectangular coordinates, and calculates continuously under the situation of distance at the utilization wheel (22) of having the records of distance by the log, measured value is stored,D) measured value according to record calculates the cross section of track switch (1),E) actual measured value that described tested point (25) is upward measured and the set-point of storage compare, in following parameters, at least to compare two parameters, that is;

    slot pitch, the continuous minimum range between cut channel, frog centre working edge and the check rail working edge, gauge and/or check rail spigot surface spacing, and determine to depart from the degree of set-point thus.
