About the project

New 130 kilometre-long line with 47 kilometres in tunnels, over 100 bridges and 23 modern railway stations and stops: Find out what is currently happening at the construction sites.

Tunnel work at the Koralm.

The Koralm Railway

It’s centrepiece - the Koralm Tunnel - is the sixth-longest railway tunnel in the world. The economic locomotive is also getting going with the construction of the high-speed line. The investments are creating many new jobs – both in construction and in the operation of the Koralm Railway.

The Koralm Railway is under construction or already completed. Trains are therefore already running on some sections, while work on others is proceeding at high speed on bridges, tunnels, open stretches of line and railway stations.

In the construction areas, you’ll learn more about the individual sections of the Koralm railway and their features - such as the Koralm Tunnel, the new bridge over the Drau river or the many new or modernised railway stations.
