Overview
- A blaze in a technical room at Wittenbergplatz was detected during the overnight pause and firefighters extinguished it quickly with no reported injuries, officials said Thursday.
- The Berlin transport operator BVG closed Wittenbergplatz and suspended the U1 entirely while U2 and U3 run only on shortened segments with limited replacement buses on affected stretches.
- BVG technicians and emergency crews are still assessing damage to switchgear and power systems and the company cannot yet say how long repairs will take, describing the disruption as "until further notice."
- Passengers face longer journeys, reduced accessibility because several station elevators remain out of service, and confusing or incomplete service information from BVG apps and web channels.
- The outage severs a key east–west link through City‑West next to KaDeWe and recalls a late‑2025 station fire that required weeks of repair, which raises the prospect of extended disruption if electrical damage proves extensive.
