Report delays, cancellations, and issues on the Wimbledon branch. Your reports build evidence for change.
This project exists to document the real experience of passengers on the District Line Wimbledon branch and hold TfL accountable for the service they provide. Specifically, we aim to show that TfL's own status reports frequently say "Good Service" when passengers are experiencing significant delays, cancellations, and overcrowding. By collating timestamped reports alongside TfL's live API data, we can demonstrate these discrepancies with hard evidence — and present that evidence to our local MP, TfL, and the Department for Transport to push for the signalling upgrades and investment this line desperately needs.
TfL used to measure the impact of delays using a metric called Lost Customer Hours, which estimated the time lost by passengers due to disruptions of two minutes or more. However, TfL stopped publishing this data after period 12 of 2019/20 — citing changes in passenger demand due to COVID. They have never resumed reporting it, even as ridership has returned to near pre-pandemic levels.
This means there is currently no official measure of the real-world impact of delays on passengers. This tracker exists to fill that gap — giving Wimbledon branch passengers a way to record and quantify the time they lose, so we can present hard evidence to our MP and TfL.
Your name will only be displayed on reports if you choose to include it — by doing so, you give us permission to show it publicly on this site. If you leave the name field blank, your report appears as "Anonymous". We only collect and store the information you submit (station, time, delay, description) for the sole purpose of collating evidence to improve District Line service and increase investment. We do not share your data with third parties or use it for any other purpose. All data may be included in reports shared with your local MP and TfL.
