Each column is one journey, headed by the time it sets off; one that finishes short of the usual end says where ("to …") — not every journey on this route runs the whole way. A · means that journey does not stop there. Times are shown at the route's main timing stops — buses serve all stops in between. Switch a table to All stops for every stop it calls at, or open a stop's own page for live departures there.

Christmas & bank holidays

These dates are not the usual timetable for the day they fall on. They come from the operator’s published data, which for Christmas and New Year is often late or incomplete, so check with London United before you travel. Everything above is an ordinary week.

Not published yet: Christmas Eve, Christmas Day, 28 December, New Year's Eve and New Year's Day. Operators often publish festive timetables only a few weeks ahead, so check again nearer the date.

• Boxing Day — Saturday, 26 December 2026
  The operator’s data lists more buses on this date than on an ordinary Saturday (305 journeys in both directions together, against 219), which usually means two timetables have been added together by mistake. Check with London United before you travel.

How busy is route K3?

1.82m passenger journeys were recorded on route K3 in 2024/25 across 809,715 kilometres operated. That is down from a peak of 1.97m in 2015/16.

Millions of passenger journeys per financial year, from Transport for London's published bus statistics. A passenger journey is one boarding of one bus — someone commuting five days a week makes ten of them, so this is not a count of people. Years marked 53w ran 53 weeks rather than 52, so they sit about 2% high against their neighbours. TfL changed how boardings were estimated in 2017 and restated 2016/17 on the new basis; the chart uses the restated figure, so years before 2016/17 are not exactly comparable with those after. Route-level totals do not sum to TfL's network figures, which carry separate adjustments. Powered by TfL Open Data. Compare every London route →
