When it goes wrong

Chance of waiting more than twenty minutes if you turn up at random, by time of day, averaged over the most recent weeks of data. The mark on each bar is the chance if everything ran to timetable.

  • Weekdays 05:00–07:00 7.7%
  • Weekdays 07:00–10:00 6.8%
  • Weekdays 10:00–16:00 4.9%
  • Weekdays 16:00–19:00 8.4%
  • Weekdays 19:00–24:00 10.5%
  • Saturdays 10.3%
  • Sundays and bank holidays 13.5%

Journeys cut short

Last week: 21.2% 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 Central Middlesex Hospital

  • Boundary Road1.2 km short of the end 1
  • Clifton Road3.3 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.
Journeys observed
  • towards Central Middlesex Hospital: 345 journeys tracked across five days
  • towards O2 Centre / Sainsbury's: 495 journeys tracked across seven days
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. Waits are measured along the route at TfL's timing points, in each direction, against the timetable — not at the ends of the route, where a bus turned back early counts as if it had run. This route runs to a timetable, but we can't yet publish a reliable on-time figure for it, so it is measured by how long people waited, as a frequent route is. A day with less than four hours of data collected shows no daily figure. How these figures are made.
