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 8.4%
- Weekdays 07:00–10:00 11.7%
- Weekdays 10:00–16:00 12.4%

- Saturdays 25.7%
- Sundays and bank holidays 35.8%
Journeys cut short
Last week: 20.3% 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: 247 journeys on route 356 were turned back before the end of the line over four weeks of watching, 26 September to 17 October 2026 — about 8.8 a day.
Where those journeys fall across the day. Each bar is the number cut short in that hour on an average day, so the bars together come to the daily figure above; hover a bar for its hour. Hours the route was not watched enough to say are shaded rather than drawn as nought.

Compared with TfL's own figures
| Quarter | TfL | Ours |
|---|---|---|
| 2025/26 Q313 Sept – 2 Jan 2026 | 83% on time | no figure |
| 2026/27 Q11 Apr – 26 Jun 2026 | 86% on time | no figure |
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 Sydenham Hill / Kirkdale: 90 journeys tracked across two days
- towards Wickham Road: 137 journeys tracked across three days
- 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.
