1. A method for measuring and displaying the track geometry of a track system using a track-driveable permanent-way machine having a control measurement system measuring a value of the track position to be corrected before a lifting and lining device, an acceptance measurement system measuring a value of the corrected track position after the lifting and lining device, and an associated output unit having a display that is visible to a user displaying the measured values, said method comprising:

  • controlling the lifting and lining device depending on the measured values of the control measurement system and the acceptance measurement system so as to achieve a predetermined target track geometry including a curvature image, a longitudinal level image and a superelevation image;

    first calculating a three-dimensional position image from the curvature image, longitudinal level image and superelevation image of the target track geometry,putting the three-dimensional position image into a perspective display so as to form a perspective position image, anddisplaying the perspective position image using the output unit, andsupplementing the perspective position image by measured error curves for track parameters including track direction, superelevation, twist, and longitudinal level.
