Overview
- A technical fire in a Wittenbergplatz switching room on September 17 forced a full shutdown of the U1 and partial suspension of the U2 while crews carried out repairs.
- The BVG says the U1 and U2 should run on their normal schedules at the start of the coming week if no unforeseen problems occur.
- A separate smaller fire under a U3 train in Zehlendorf on October 1 briefly halted the line’s southern section but staff quickly extinguished the blaze and service resumed the same day.
- Both incidents were linked to electrical faults—a damaged Sicherungskasten at Wittenbergplatz and a suspected fault in a Stromabnehmer under the U3 train—and caused no injuries because they occurred during low-occupancy periods.
- Passengers should expect night-time replacement buses and planned works to continue through November 12, a constraint that could prolong late-evening disruptions even after daytime service is restored.
