The U6 underground line connects the district of Möhringen with the industrial area “Am Schelmenwasen”. The double-track underground railway tunnel crosses below the industrial area „Fasanenhof”.
The Roppen tunnel between Innsbruck and Landeck in Austria was made safer by the construction of the second tube. The 5,069 meter long tunnel was driven conventionally.
The centrepiece of the 125 km long, double-track high-speed line between Graz and Klagenfurt is simultaneously the key project for the Baltic-Adriatic-Corridor. The Koralm Tunnel improves the traffic link between Graz and Klagenfurt.
