Caledonian Sleeper

Caledonian Sleeper appears on 94 archived days from 6 Aug 2026 to 7 Nov 2026, running 9 services a day. 78% of its recorded arrivals were within five minutes, which is below the network as a whole.

625 arrivals were recorded across the window, 490 of them within five minutes and 52 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 Friday, 6 November 2026 against 3 on Saturday, 24 October 2026, a swing of 3.3 times.

The average delay at destination was 1.3 minutes. The worst single arrival recorded was 4h 04m behind schedule, Fort William to Edinburgh on Sunday, 25 October 2026.

60 services were cancelled, 7.5% of everything booked — above the 2.3% 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 78% of recorded arrivals to 72% of everything booked whose outcome is known — 6.9 points.

Ranked on on-time share of recorded arrivals against the 34 operators with enough of them to compare, Caledonian Sleeper comes 24th.

Caledonian Sleeper in numbers

Every percentage among the bands is of the 625 services whose arrival reached the archive, not of all 805, and the bands are exclusive. 120 ran without an arrival being recorded, and nothing is claimed about those. The row counting cancellations is those same 490 on-time arrivals over a denominator that also holds the 60 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
