Malmö Citytunnel
Sweden, Malmö
2006 – 2008

In the southern Swedish city of Malmö, a bottleneck situation has arisen for rail traffic coming to and going from the Öresund Bridge, the most important connection to and from Denmark. The expansion of the bottleneck is to be achieved through two single-track railway tunnels which run beneath Malmö city center, creating a new connection southwards starting from the central railway station.

The “Anna” and “Katrin” EPB Shields of identical design set off from Holma toward the railway station. The task was to create two tunnels of 4,289 and 4,592 meters in length over the next few months. “Anna” commenced her underground journey in Holma in late November 2006 and concluded her first section after nine months of travel on August 21, 2007. It took another seven months to cover the subsequent kilometers between Trangeln and reach the ultimate destination of “Malmö C”, achieving an average speed of 15 meters a day. Best performance was 36 meters. “Katrin” reached her intermediate station in September 2007 and the target shaft at the central railway station in April 2008.
