Overview
- The Stammstrecke closure, which begins Tuesday at 22:40 and lasts to April 13 at 04:40, halts through‑tunnel service and forces most lines to turn at Hauptbahnhof, Stachus, Ostbahnhof, Trudering, or Giesing, with S7 largely unaffected.
- DB sets temporary routings with no bus bridge in the city tunnel, and directs riders to U‑Bahn and trams, including extra U4 trips from Heimeranplatz for S6 passengers and easy transfers at Stachus and Ostbahnhof.
- Regional trains on the Mühldorf–Munich corridor are suspended through April 13 at 05:20, with buses serving all regular stops to München Ost and direct coaches from Mühldorf, Ampfing, and Dorfen to Messestadt Ost for U2 transfers, plus a moved stop from Thann‑Matzbach to Lengdorf Ort.
- Two inner‑city stops stay closed longer than the tunnel itself, with Rosenheimer Platz skipped until April 15 at 04:40 and Isartor until April 18 at 08:00.
- Holiday travel strains are set to rise, as ADAC warns of heavy road traffic and Munich Airport expects about 2.1 million passengers by April 12, so DB urges travelers to plan extra time and check the app for updates.
