Stuttgart–Ulm Rail Project: Imberg Tunnel

The Imberg Tunnel is located on the Swabian Alb plateau, which is crossed by the new Wendlingen–Ulm rail link. It is 499 m long, which means it is numbered among the shortest for the Stuttgart–Ulm rail project. The ICE will only need roughly 7 seconds to pass through the tunnel. Topographical marginal conditions define the length of the 220 m central construction section, which is driven by conventional means. Cut-and-cover sections extend the tunnel at both sides. On the south side this is defined by the planned or rebuilt road network; at the north side a highly frequented game pass that crosses the track has to be catered for.
