How we calculate reliability
- Time-weighted: Reliability is the percentage of operational time with “Good Service”, not a count of incidents. A 23-hour good day with a 1-hour delay scores ~96%, not 50%.
- Operational hours only: Normal overnight closures (“Service Closed”) and planned closures are excluded so they don’t deflate scores.
- Status change tracking: We record every status change from the TfL API (polled every 60 seconds), then calculate the duration of each status period.
- Peak hours: Peak-hour figures cover weekday mornings (07:00-09:30) and evenings (16:30-19:00) only. All-hours figures include the full operational day.
- Refresh frequency: Statistics on this page are recalculated every 5 minutes. Day-of-week patterns are based on the last 90 days of data.
- Data source: All data comes from the Transport for London Unified API.
- New lines: DLR, Elizabeth line, and Tram were recently added to our monitoring. Annual statistics for these lines will become available once a full year of data has been collected.

About the Northern line
The Northern line is a love-hate classic: quick, useful, and absolutely rammed when London is commuting. The branches and 'via Bank / via Charing Cross' split add extra ways to accidentally end up somewhere else. It's brilliant for Camden Market, and for Battersea Power Station when you want food, bars, and a riverside stroll. Check live status so you don't get caught in the crush.
