90 minutes was the longest gap between buses this week, at Swan & Sugar Loaf towards Purley High Street, on Sunday 11 October from 21:03 to 22:33. This excludes any gaps caused by holes in our own data. Watch it happen →

Journeys cut short

Last week: 0.7% 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.

towards Purley High Street

Last week, none of 248 journeys was turned short.

towards Park Street

Last week, 4 of 297 journeys (1%) were turned short.

  • Croydon Flyover0.7 km short of the end 3
  • Selsdon Library5.2 km short of the end 1

Each place is the last stop the bus was timed at before it turned round, with the typical distance it fell short of the end of the line. The five busiest are named; the rest are counted together.

TfL's figures come from its own tracking equipment and its own timetable; mine are computed from the buses' public position feed. They are the same calculation on independent data, so they should broadly agree and move together rather than match exactly.

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.
