Journeys cut short

Last week: 7.5% of journeys were turned back before the end of the line in the week ending 17 October 2026. Everyone on board has to get off; for anyone waiting further along the route it's effectively a cancellation.

Last four weeks: 266 journeys on route 440 were turned back before the end of the line over four weeks of watching, 26 September to 17 October 2026 — about 9.5 a day.

About this data
Data collected, week ending 17 October 2026
100% of the week. This is the share of the week for which we hold bus location data at all, across the whole of London rather than for this route. A week under 60% is not published; under 90% it is marked as thin.

A guide to how much evidence sits behind this week's figures, not a measure of the service.
How it is measured
Every day, 05:00–23:59. On time means leaving no more than 2.5 minutes early or 5 minutes late. A day with less than four hours of data collected shows no daily figure. How these figures are made.
