TfL sorry as severe Northern line delays enter fifth day
A signal failure at Stockwell means controllers are manually talking trains through the area.
www.bbc.comHere are the latest highlights on the Northern Line:
- A major signal fault and related delays have affected parts of the Northern Line in recent days, with TfL advising customers to allow extra travel time and to check live updates before traveling.[1]
- In early 2026, TfL announced a temporary early-closure window for the Bank branch of the Northern Line to carry out essential track work, lasting about four months and aiming to improve long-term reliability, with monitoring of service impacts on adjacent branches.[2]
- Ongoing disruption stories from 2024–2025 show periodic closures and signal-related delays impacting Kennington to Camden Town via Bank, as well as occasional station works on related lines that influence Northern Line performance.[3][4]
If you’d like, I can fetch the very latest live status from TfL and summarize any service changes for today. I can also provide a quick map of affected branches and recommended alternatives.
