Koralm railway
A fast and safe service between Styria and Carinthia: That’s the Koralm Railway. It’s part of the new Southern Line in Austria and one of the most important infrastructure projects in Europe.

The Koralm railway connects the Austrian cities of Graz and Klagenfurt. It is 126 km long and designed for a maximum speed of 250 km/h. Centerpiece is the 33 km long Koralmtunnel. It has two tunnels, which are covered by the Koralpe mountain range at a height of up to 1,200 meters. Construction started in 1999 and the line will open on 14. December 2025.
