Overview
- Deutsche Bahn began the four‑week closure on Monday, Oct. 26, with work to replace switches south of Hamburg Hauptbahnhof scheduled to run until Nov. 22.
- Most Regionalexpress, regional and many long‑distance services will be canceled on the Harburg–Hauptbahnhof leg or will start and end at Harburg instead of the Hauptbahnhof.
- Operators increased S‑Bahn frequency from Harburg to roughly every five minutes and placed DB staff on platforms, and the city and transit agencies added a limited direct bus service between Wilhelmsburg/Veddel and the Hauptbahnhof.
- The morning peak on the first day remained manageable, but DB and on‑site staff warn that evening rush hours are likely to see heavy crowding and longer travel times.
- Passengers are advised to allow extra time, avoid Hamburg Hauptbahnhof where possible, and check specific affected routes such as RE5 to Cuxhaven and Metronom services toward Lüneburg, Uelzen, Bremen and Rotenburg.
