The Stuttgart–Ulm rail project with the new Wendlingen–Ulm route is numbered among the biggest development schemes for public rail transportation in Germany. Altogether 20 tunnels are being...
The Kö-Arch Tunnel in Düsseldorf is the first tunnel in Germany to be completely illuminated by LED technology. The tunnel is part of the complex “Kö-Arch” urban construction concept, which diverts traffic in the city centre underground in favour of green areas and pedestrian routes. The entire tunnelling project at Düsseldorf’s Kö-Arch is due to be completed by the end of 2015.

The Austrian Society for Construction Technology (ÖBV) stages a construction congress every two years for clients, the construction and building materials industry as well as for engineering offices. 1800 participants from twelve countries attended the event in Vienna in April. Numerous papers among the 50 lectures dealing with research and development, practice and project development, which are available in a 122-page set of Proceedings dealt with infrastructure and underground construction.

Deutsche Bahn’s newly built route from Wendlingen to Ulm is a mecca for discerning tunnel builders. This is because half of the route passes through tunnels, which cut through a wide range of different rock strata. A variety of construction methods are required: To create the first tunnel, the Steinbühl tunnel, the shotcrete construction method is used. The 4.8 km long Steinbühl tunnel, together with the Boßler tunnel, will help trains with the difficult climb at Albaufstieg. It is entered at Hohenstadt, at an altitude of 746 metres, close to the A8 Autobahn. In eight years’ time, trains will be racing through it at 250 km/h.
The 43 km long, largely single-track line between Berne and NeuchâtelIt is currently being developed with twin tracks by the private Swiss rail company BLS AG. The new 2080 m long, twin-track Rosshäusern Tunnel represents the core of the Rosshäusern-Mauss construction section. A change in the method of driving bringing with it greater industrial safety was decided on resulting from difficult geological circumstances as work progressed and a tragic accident with fatal consequences. As further fault zones had to be reckoned with as work went on it was decided to adopt the crown driving method with pipe umbrella in rock.
