Method for measuring and displaying the track geometry of a track system

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, and
• displaying the perspective position image using the output unit, and
• supplementing the perspective position image by measured error curves for track parameters including track direction, superelevation, twist, and longitudinal level.
