The tunnel will be 32.9 km (20.4 mi) long, which will make it Austria's longest railway tunnel.[2][3] 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.
