Munich second S-Bahn main line construction
Overview
The construction of Munich’s second S-Bahn main line has progressed from public demonstration to active drilling. In early September, Deutsche Bahn and the Arbeitsgemeinschaft Tunnel Hauptbahnhof (ATH) held an open house at the construction site to showcase the ‘Donna Maria’ tunnel boring machine. The 178-meter-long, 700-ton machine was presented to the public to highlight the technical challenges of urban tunnel construction.
By mid-September, the ‘Donna Maria’ began drilling the first exploration and rescue tunnel for the project. This tunnel is intended to create a new route between Laim and Ostbahnhof to relieve the existing main line. The machine is expected to drill a three-kilometer route from the Donnersbergerbrücke area to Marienhof over approximately one year, operating at depths of up to 40 meters and excavating an estimated 150,000 tons of earth and rock.
As of late September, the ARGE Tunnel Hauptbahnhof—a consortium including Wayss & Freytag, Max Bögl, Züblin, and Bauer Spezialtiefbau—has successfully launched the mechanical excavation. The ‘Donna Maria’ is a Mixshield machine developed in collaboration with Herrenknecht, specifically designed for Munich’s geological conditions. During the drilling process, which averages a progress of eight meters per day, the excavated material will be distributed to twenty different landfills via truck and rail. The completed tunnel will serve as a vital rescue and exploration route between the two future S-Bahn traffic tunnels.
