In Berlin, a major U-Bahn disruption is on the horizon. Beginning in January 2026, the central Nollendorfplatz U-Bahn station will be closed for approximately four months due to significant structural damage in the tunnel ceiling. This closure will affect three key lines: U1, U3, and U4. This was reported by G.Business , citing information from rbb24.
According to the Berliner Verkehrsbetriebe (BVG), this is not an emergency measure but part of a long-planned modernization effort. The ceiling defects were discovered earlier, and protective steps had already been taken, including removing ceiling panels and introducing a speed limit for incoming trains. The upcoming work aims to permanently eliminate the weaknesses in the steel-reinforced concrete ceiling.
These U-Bahn lines are affected
- U1: Shuttle service between Wittenbergplatz–Uhlandstraße and Gleisdreieck–Warschauer Straße
- U3: Will operate only between Krumme Lanke and Spichernstraße
- U4: Entire service will be suspended for the duration of the renovation
The U2, which runs above ground at Nollendorfplatz, will not be affected by the closure.
The BVG is currently developing a replacement transport plan, and details regarding diversion routes and passenger information will be announced in due course.
Background: What caused the closure
Inspection documents revealed large voids in the reinforced concrete at two points of the intermediate ceiling. As a safety precaution, ceiling coverings were removed years ago, and a reduced speed limit was enforced. Now, the comprehensive reconstruction will secure the long-term structural integrity of this key transit hub.
