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 Mildmay line

The Mildmay line is London's orbital cheat code, getting you across the city without diving into Zone 1. It's great for Hackney Wick canalside pints and local venues, but it runs on a busy rail corridor with freight and complex junctions, especially around Willesden Junction, so reliability can wobble. Check live status before you bank on a tight connection.
