How we count

TfL used to measure the impact of delays with a figure called Lost Customer Hours: the time passengers lost to disruptions of two minutes or more. It stopped publishing it after period 12 of 2019/20, citing changes in passenger demand during COVID, and no longer reports it by line. So there is no public measure of how much time delays cost passengers on the Wimbledon branch.

This tracker fills that gap. Passengers record the time they lose, and the “time lost” figures above multiply each delay by the number of people affected (the reporter plus everyone who tapped “Me too”), so we can put the evidence in front of our MP, TfL and the Department for Transport.
