Due to damage of the superstructure (cracks at the track supporting layer, failure of the conductor rail anchors), measurements along the underground line U3 (Station Herrengasse) were carried out during the daily routine, concerning the deflection of the tracks. The results showed absolute deflection and settling of the track supporting layer. Similar measurements were done to assess the underground’s power rail and their fixation.
For comparing reasons the same assessment of track supporting layer and power rail was made in a section without superstructure damage (Station Neubaugasse).
