Great Northern

Great Northern appears on 94 archived days from 6 Aug 2026 to 7 Nov 2026, running 420 services a day. 81% of its recorded arrivals were within five minutes, which is below the network as a whole.

27,452 arrivals were recorded across the window, 22,237 of them within five minutes and 288 more than half an hour late. At this volume a single badly delayed working is worth a visible fraction of a percentage point.

Its week is strongly peaked: 809 services on Sunday, 30 August 2026 against 229 on Sunday, 16 August 2026, a swing of 3.5 times.

The average delay at destination was 3.1 minutes. The worst single arrival recorded was 2h 46m behind schedule, London Kings Cross to Ely on Tuesday, 8 September 2026.

The day-to-day spread is wide — 42 points between its best day, Sunday, 18 October 2026 at 99%, and its worst, Tuesday, 15 September 2026 at 57%.

1,416 services were cancelled, 3.6% of everything booked — above the 2.3% the network cancelled over the same dates. The worst single day was Saturday, 12 September 2026, at 21% of that day's timetable.

Counting those cancellations as failures, the way the industry's own measure does, takes the on-time share from 81% of recorded arrivals to 77% of everything booked whose outcome is known — 4.0 points.

Ranked on on-time share of recorded arrivals against the 34 operators with enough of them to compare, Great Northern comes 21st.

Great Northern in numbers

Every percentage among the bands is of the 27,452 services whose arrival reached the archive, not of all 39,499, and the bands are exclusive. 10,631 ran without an arrival being recorded, and nothing is claimed about those. The row counting cancellations is those same 22,237 on-time arrivals over a denominator that also holds the 1,416 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.
