Journeys cut short

Last week: 1.4% 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 Epsom High Street

Last week, 9 of 352 journeys (3%) were turned short.

  • Mongers Lane1.7 km short of the end 4
  • Ewell East Station2.7 km short of the end 2
  • Windmill Lane1.1 km short of the end 1
  • Reigate Road / Green Man1.9 km short of the end 1
  • Edinburgh Road12.5 km short of the end 1

towards St Helier Station

Last week, 1 of 340 journeys (0%) were turned short.

  • Benhill Wood Road3.9 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.
