Southern

Southern recorded 79,831 services from 6 Aug 2026 to 23 Sept 2026 and cancelled 3,039 of them. Of those whose arrival was captured, 83% were within five minutes — below the national figure for the same days.

Over 49 archived days that is 1,629 services a day, 6.6% of the national timetable. Of 56,433 recorded arrivals, 46,726 were within five minutes and 415 were more than half an hour down.

Its week is strongly peaked: 1,800 services on Wednesday, 19 August 2026 against 1,104 on Sunday, 9 August 2026, a swing of 1.6 times.

The average delay at destination was 2.5 minutes. The worst single arrival recorded was 2h 50m behind schedule, London Victoria to Littlehampton on Thursday, 17 September 2026.

The day-to-day spread is wide — 21 points between its best day, Tuesday, 22 September 2026 at 90%, and its worst, Sunday, 16 August 2026 at 69%.

3,039 services were cancelled, 3.8% of everything booked — above the 2.4% 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 83% of recorded arrivals to 79% of everything booked whose outcome is known — 4.2 points.

Ranked on on-time share of recorded arrivals against the 30 operators with enough of them to compare, Southern comes 18th.

Southern in numbers

Every percentage among the bands is of the 56,433 services whose arrival reached the archive, not of all 79,831, and the bands are exclusive. 20,359 ran without an arrival being recorded, and nothing is claimed about those. The row counting cancellations is those same 46,726 on-time arrivals over a denominator that also holds the 3,039 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
