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.
