Hamburg U1 subway line halted after train brake fire scare

A technical fault disrupted services on Hamburg’s U1 subway line on Thursday morning. The issue involved a train at Hallerstraße station, where reports of a fire in the braking system triggered an emergency response. Firefighters were called to Hallerstraße station after smoke was detected. They arrived to find light smoke inside the station but no active flames. The fire had started in the train’s brake assembly and spread to the control unit.

The station was evacuated as a precaution. Emergency crews ventilated the area to clear the smoke. No injuries were reported during the incident.

As temperatures in the affected train dropped, firefighting operations were not required. However, the train could not continue its journey and had to be towed away. The disruption was caused by overheating in the braking system. Services on the U1 line faced delays while the situation was resolved. The train was removed from service for further inspection.
