C: Munich 2nd Core Line (Tunnel Portal West)
The Munich S-Bahn carries around 840,000 passengers a day and covers over 20 million kilometres a year. The main line, which was opened in 1972 for the Olympic Games, is thus reaching its capacity limits, especially since all S-Bahn trains have to pass under Munich city centre through one tunnel. This situation is remedied by the construction of the approximately 10 km long 2nd core line (2. S-Bahn-Stammstrecke). It is intended to relieve the existing route and serve as a fallback option in the event of a disruption. At the heart of the project are two single-track, seven-kilometre-long tunnels connecting the main station and the Ostbahnhof. In addition to the two above-ground interchange stations Laim and Leuchtenbergring, which will be rebuilt during ongoing operations, the three new underground stations Hauptbahnhof, Marienhof and Ostbahnhof will be completely rebuilt. As part of the STUVA conference, expert visits to four different construction sites of the 2. S-Bahn-Stammstrecke will be offered.
Tunnel portal west:
Near the Donnersberg bridge, the future tunnel portal West is being built in the west of Munich. From here, the tunnel tubes will be driven in the direction of Marienhof. During the technical excursion, the ongoing work for the construction of the cut-and-cover tunnel as well as the preparations for the start of the tunnel boring machines will bepresented.
