Koralm Tunnel: The first breakthrough is imminent

Posted: 6 June 2018 | | No comments yet

Work on the Koralm railway between Graz and Klagenfurt in Austria is running at full throttle with 90 per cent already under construction or completed. The next big upcoming milestone is one of the most important to date – the first breakthrough in the Koralm Tunnel.

The 130km-long Koralm railway is one of the most important transport infrastructure projects in Europe. It is part of the new Southern line and thus an essential section of the Baltic-Adriatic corridor. From an Austrian point-of-view, the Koralm railway represents a decisive structural improvement, especially for southern Austria as a business location. The shortest travel time between Graz and Klagenfurt will be reduced from almost three hours at present to just 45 minutes.

Ninety per cent under construction

The heart of the project is the 33km-long Koralm Tunnel. In addition, the new high-performance line consists of 12 new stations, over 100 bridges and numerous other tunnels. Approximately 90 per cent of the high-performance line is now under construction or completed. With the exception of one section between Feldkirchen and Weitendorf, all sections are either under construction or complete. In particular, the tunnelling work on the Stein, Lind, Peraschitzen and Srejach tunnels in Carinthia, some of which have very difficult geology, and the tunnelling work on the Granitztal tunnel chain, have been successfully completed. The structural engineering work for the future high-speed train station in Western Styria has been in full swing since 2017.
