The Koralm Tunnel is a railway tunnel that is under construction in Austria under the Koralpe mountain range. It is expected to be operational by 2022.
The tunnel will be 32.9 km (20.4 mi) long, which will make it Austria's longest railway tunnel. Running at depths of up to 1,250 m (4,100 ft) below ground, the tunnel will be a part of the 130 km (81 mi)-long Koralm Railway which will link Graz with Klagenfurt. The Koralm tunnel will be composed of two tunnels running in parallel, each capable of carrying a single railway track, which will be linked together every 500 metres (1,600 ft).
An emergency stopping point at the middle of the tunnel is included in the plans.
