Southern

Southern recorded 154,518 services from 6 Aug 2026 to 7 Nov 2026 and cancelled 4,548 of them. Of those whose arrival was captured, 84% were within five minutes — below the national figure for the same days.

Over 94 archived days that is 1,644 services a day, 6.6% of the national timetable. Of 122,737 recorded arrivals, 103,439 were within five minutes and 759 were more than half an hour down.

Its week is strongly peaked: 1,984 services on Wednesday, 28 October 2026 against 1,104 on Sunday, 9 August 2026, a swing of 1.8 times.

The average delay at destination was 2.3 minutes. The worst single arrival recorded was 3h 08m behind schedule, Arundel to London Victoria on Sunday, 27 September 2026.

The day-to-day spread is wide — 22 points between its best day, Saturday, 7 November 2026 at 91%, and its worst, Sunday, 16 August 2026 at 69%.

4,548 services were cancelled, 2.9% of everything booked — above the 2.3% the network cancelled over the same dates. The worst single day was Saturday, 15 August 2026, at 11% of that day's timetable.

Counting those cancellations as failures, the way the industry's own measure does, takes the on-time share from 84% of recorded arrivals to 81% of everything booked whose outcome is known — 3.0 points.

Ranked on on-time share of recorded arrivals against the 34 operators with enough of them to compare, Southern comes 18th.

Southern in numbers

Every percentage among the bands is of the 122,737 services whose arrival reached the archive, not of all 154,518, and the bands are exclusive. 27,233 ran without an arrival being recorded, and nothing is claimed about those. The row counting cancellations is those same 103,439 on-time arrivals over a denominator that also holds the 4,548 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.

Day by day
