Caledonian Sleeper
Caledonian Sleeper appears on 49 archived days from 6 Aug 2026 to 23 Sept 2026, running 8 services a day. 83% of its recorded arrivals were within five minutes, which is below the network as a whole.
281 arrivals were recorded across the window, 232 of them within five minutes and 17 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: 10 services on Tuesday, 22 September 2026 against 3 on Saturday, 19 September 2026, a swing of 3.3 times.
Averaged across every recorded arrival its trains finished 2.8 minutes ahead of schedule rather than behind it, the early arrivals outweighing the late ones. The worst single arrival recorded was 3h 51m behind schedule, Edinburgh to Fort William on Friday, 21 August 2026.
45 services were cancelled, 10.8% of everything booked — above the 2.4% the network cancelled over the same dates.
Counting those cancellations as failures, the way the industry's own measure does, takes the on-time share from 83% of recorded arrivals to 71% of everything booked whose outcome is known — 11.4 points.

Every percentage among the bands is of the 281 services whose arrival reached the archive, not of all 415, and the bands are exclusive. 89 ran without an arrival being recorded, and nothing is claimed about those. The row counting cancellations is those same 232 on-time arrivals over a denominator that also holds the 45 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.
