Track recording cars filter machines

The track survey car EM-SAT 120 measures the deviations of a track from its ideal line due to train movements. Using a combination of fixed-point measurement (fixed-point measuring device) and laser measuring, the elevation and displacement values ​​are measured at a distance of 5 meters with an accuracy of +/- 1 millimeter. Then the measured data will be compared with the desired geometry from the geometry database, the control data is determined and transferred directly to the tamping machine.
