How much does Munich's second S-Bahn trunk line tunnel cost?
Trunk line 2 (zweite Stammstrecke) of the Munich S-Bahn is the 11.9 km second tunnel through the city centre from Laim via Hauptbahnhof, Marienhof and Ostbahnhof, approved in 2016 with funding of EUR 3.85 billion and a completion date of 2026, with the ground-breaking ceremony on 5 April 2017. The cost has since risen: Deutsche Bahn calculated about EUR 7 billion in September 2022, with a EUR 1.5 billion risk buffer and Bavaria's share of EUR 3.7 billion, and t-online reported on 28 January 2025 current total costs of EUR 7.06 billion plus inflation, with opening forecast for December 2036.
