The current information available suggests that disruptions on the Northern line are being caused by signalling faults, with engineers actively working to restore normal service. The exact timing for a full restoration can vary and depends on the nature of the fault and the progress of repairs. Please check live updates from TfL and the Tube status pages for the most accurate, real- time timetable changes. You can also consider alternative routes or travel times and sign up for service alerts. What to do next for precise timing

• Check TfL’s Northern line status page and Journey Planner for live disruption notices and revised timetables.
• Look at TfL Go app notifications or the National Rail/ TfL status feeds for real-time outage duration estimates.
• If you must travel, plan alternative routes (e.g., buses, other Underground lines, or Overground segments) and allow extra time.
