Overview
- Berlin’s BVG will close Nollendorfplatz from January 12 to mid‑May 2026 to replace severely water‑damaged tunnel ceilings, suspending U4 and splitting U1/U3, with the U2 boosted to a four‑minute headway and frequent SEV buses for U3 and U4.
- Cologne Hauptbahnhof reopened after a ten‑day blockade, but a software error prevented commissioning of a new interlocking; Deutsche Bahn plans a shorter follow‑up closure in spring 2026 to complete the work.
- An overhead‑line strike by a lorry at Großenhain continues to disrupt the Berlin–Dresden corridor, with IC trains diverted via Riesa, regional stops at Lampertswalde and Ortrand skipped, bus bridges in place and delays that may persist for days.
- From December 1 to 21, digitalisation works around Stuttgart will cut and divert services, send some ICEs via Esslingen, suspend the Bad Cannstatt–Fellbach section and replace S‑Bahn links with buses.
- Further adjustments include SEV after a derailment near Hopferau, a morning switch failure that curtailed Munich S‑Bahn services, planned closures around Erfurt/Eisenach from November 29 to December 4, and local tram works in Düsseldorf.
