The construction of a flyover, for the main line to pass over the suburban lines at the new Vienna central station Wiener Hauptbahnhof, was a challenging task for the SUZ 500 high-speed track relaying train of SWIETELSKY Baugesellschaft m.b.H.
With this flyover, a direct main line has been built that allows trains to run directly from South to North on a dedicated line, without the need to pass over turnouts or crossings. The tracks of the extended Pottendorfer line will run uninterruptedly from Wien-Meidling to Wien-Hauptbahnhof.
This will make traffic management considerably easier and increase the safety on the line that will have to cope with 60 to 65 trains per day in 2015. Moreover, the traffic volume at the flyover will further increase once the Pottendorfer line has been upgraded to double track.
