Saturday, 12 September 2026

Saturday, 12 September 2026 was a poor day on the railway: of the 16,627 passenger trains whose arrival was recorded, 90% were within five minutes, and a further 833 were cancelled outright.

A weekend timetable, so the 24,952 recorded runs are well below a weekday's — most engineering possessions land here too, which shortens some routes and removes others entirely.

1,527 trains arrived more than five minutes late and 68 more than half an hour, against 15,032 that ran to time. The average delay across every train whose arrival was recorded was 1.1 minutes.

The reason attached most often to a late train was “This service has been delayed by a late running train being in front of this one” — 465 services carried it. Darwin publishes these as complete sentences written for passengers, so they appear here unedited.

The busiest hour was 17:00, with 1,493 booked departures and an average delay of 1.9 minutes.

Every percentage among the bands is of the 16,627 trains whose arrival reached the archive — not of all 24,952, and the bands are exclusive. 7,492 trains ran without an arrival time being recorded, and nothing is claimed about how punctual those were. Delay is judged at the destination, a stricter test than the industry's own measure and not comparable with it.

By operator

38 operators ran passenger services on this date, from ScotRail on 2,914 runs down to Caledonian Sleeper on 3. Ordered by volume, not performance — any heading re-sorts it.

“On time” is of each operator's recorded arrivals; “incl. cancelled” counts a cancellation as a failure, which is what the industry's own measure does. Across the whole day they read 90% and 86% — why both are published, what each hides, and how the sort treats a small operator.

What ran

Formations were recorded for 24,026 trains on this date, made up of 2,602 individual units and 11,403 separate vehicles. These figures cover the services an allocation was published for, not every train that ran.

25 different classes of train appeared, which is the signature of a full weekday — the long-distance fleets, the regional diesel units and the suburban electrics all working at once.

The most-used class was the 377, allocated to 2,391 of the day's recorded trains from a pool of 173 units.

The average train was 5.5 vehicles long. The longest formation recorded was 24 vehicles.

Buses

15,586 buses from 157 operators were seen on this date, across 2,803,579 position reports.

127,479 bus journeys were followed to their destination on this date. 89,740 arrived on time, 7,448 late, and 30,291 — 24% — arrived ahead of schedule.

Early arrivals are normal rather than exceptional. Bus running times carry enough slack to survive traffic, and it is concentrated in the last leg, so a clear run simply finishes sooner than booked.

The average arrival was 0 minutes late, and 640 journeys finished more than twenty minutes down.
