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 Circle line
Despite the name, the Circle line isn't just a simple loop. It runs from Hammersmith to Edgware Road, and shares track with other sub-surface lines, so delays love to spread. It's great for a museum day via South Kensington, or a wander around Notting Hill when London decides to be sunny. Check live updates, because gaps can be surprisingly annoying.
