Southeastern

Between 6 Aug 2026 to 23 Sept 2026, Southeastern ran 79,021 recorded services and finished the period on 86% of its measured arrivals within five minutes, within a couple of points of the network as a whole.

Over 49 archived days that is 1,613 services a day, 6.6% of the national timetable. Of 60,541 recorded arrivals, 52,197 were within five minutes and 353 were more than half an hour down.

Its week is strongly peaked: 1,830 services on Tuesday, 25 August 2026 against 897 on Sunday, 30 August 2026, a swing of 2.0 times.

The average delay at destination was 2.1 minutes. The worst single arrival recorded was 3h 49m behind schedule, Gravesend to London Victoria on Tuesday, 18 August 2026.

Between Friday, 4 September 2026 at 73% and Saturday, 12 September 2026 at 93% there are 19 points.

1,198 services were cancelled, 1.5% of everything booked — below the 2.4% the network cancelled over the same dates. The worst single day was Tuesday, 18 August 2026, at 9% of that day's timetable.

Counting those cancellations as failures, the way the industry's own measure does, takes the on-time share from 86% of recorded arrivals to 85% of everything booked whose outcome is known — 1.7 points.

Southeastern in numbers

Every percentage among the bands is of the 60,541 services whose arrival reached the archive, not of all 79,021, and the bands are exclusive. 17,282 ran without an arrival being recorded, and nothing is claimed about those. The row counting cancellations is those same 52,197 on-time arrivals over a denominator that also holds the 1,198 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.
