Koralm train underground lines

Above, through below

Regardless of whether it is a bridge or an underground line, the engineers at Thomas Lorenz ZT GmbH master both. In 2003, a three-stage, EU-wide negotiated procedure for the static-constructive processing and architectural design of the underground routes on the Koralm lift in Styria was carried out. The bidding consortium Eisner–Lorenz–Seib came out of this application process as the best bidder with a draft by Martin Zechner and was commissioned in January 2004 to carry out the planning work.

Facts

The underground route FW 12 was planned in the Wundschuh–Wettmannstätten section in the area of the Weitendorf motorway junction as an underpass for the A9 Phyrnautobahn. The structure consists of a 475 m long tub and an 800 m long underpass. In the area of the airport, a second underfloor route – the FW 2 object – is being implemented. The property, consisting of underpass and tubs, has a total length of 5.6 km. The possibility of a later connection to the airport was taken into account.
