London Overground

96% of London Overground's 55,292 recorded arrivals from 6 Aug 2026 to 23 Sept 2026 were within five minutes, putting it 8.4 points clear of the network average for the same dates.

Over 49 archived days that is 1,552 services a day, 6.3% of the national timetable. Of 55,292 recorded arrivals, 52,948 were within five minutes and 25 were more than half an hour down.

Volume moved between 1,234 services on Sunday, 23 August 2026 and 1,673 on Saturday, 15 August 2026.

The average delay at destination was 0.1 minutes. The worst single arrival recorded was 2h 25m behind schedule, Gospel Oak to Barking Riverside on Wednesday, 19 August 2026.

Across every comparable day in the window the on-time share stayed between 90% and 99%, a range of 8 points — its best day was Sunday, 23 August 2026 and its worst Wednesday, 19 August 2026.

3,654 services were cancelled, 4.8% of everything booked — above the 2.4% the network cancelled over the same dates. The worst single day was Thursday, 20 August 2026, at 14% of that day's timetable.

Counting those cancellations as failures, the way the industry's own measure does, takes the on-time share from 96% of recorded arrivals to 90% of everything booked whose outcome is known — 5.9 points.

Ranked on on-time share of recorded arrivals against the 30 operators with enough of them to compare, London Overground comes fifth.

London Overground in numbers

Every percentage among the bands is of the 55,292 services whose arrival reached the archive, not of all 76,072, and the bands are exclusive. 17,126 ran without an arrival being recorded, and nothing is claimed about those. The row counting cancellations is those same 52,948 on-time arrivals over a denominator that also holds the 3,654 trains that did not run at all. Delay is judged at the destination, a stricter test than the industry's own measure and not comparable with it. The on-time share and the average delay answer different questions.
