SEGMENTS INSTALLED
After its completion, with a length of 8,176 meters the Albvorland Tunnel near Kirchheim unter Teck will be one of the ten longest railway tunnels in Germany. It is a section of the new line between Stuttgart and Ulm expanding a trans-European east-west main line for high-speed traffic. The tunnel consists of two single-track tunnel tubes, which are being lined with a total of around 60,000 segments (outer diameter 10,500 mm, width 2,000 mm). Mechanized tunnelling has been underway since November 2017 with two EPB Shields from Herrenknecht AG.
