How are delay hours calculated?
Campaigners likely calculate lost hours by multiplying the number of affected passengers by the average delay duration. For example, if 10,000 commuters are delayed by 15 minutes, that's 2,500 hours lost. This method highlights the cumulative impact of disruptions on thousands of individual journeys, as seen on the District Line.
