Overview
- Service controllers are manually talking trains through the Stockwell area, cutting throughput to as few as 6–8 trains per hour on sections that typically handle around 15.
- TfL has not found the root cause despite days of overnight work and advanced diagnostic checks, and it has apologised to passengers for ongoing delays and crowding.
- Alternative travel remains in place with tickets accepted on London Buses, London Trams, South Western Railway, Thameslink and Southeastern.
- Officials say disruption could last until later in the week and could extend into next week, with the weekend Night Tube potentially paused to allow deeper inspections.
- Engineers have ruled out a cyber-attack or deliberate sabotage, as separate weather-related issues are also hitting services including a Piccadilly line shutdown between Rayners Lane and Uxbridge and Overground suspensions after track obstructions.
