London Delay Tracker

Live TfL delay tracker for London

This tracker monitors real-time disruptions across the entire TfL rail network — London Underground (tube), Elizabeth line, DLR, and Overground — polling the TfL Unified API every 2 minutes. Every recorded delay is logged and accumulated so you can see not just what's happening now, but the full picture over time.

What does a TfL delay cost London?

Using the Department for Transport's official value of travel time (£0.209 per passenger-minute, blended across commuting and leisure), scaled by actual TfL ridership patterns throughout the day, the tracker calculates the real economic cost of each disruption to London's economy.
