Friday, 4 September 2026

86% of the 21,862 passenger trains whose arrival was recorded on Friday, 4 September 2026 reached their destination within five minutes — an ordinary day, with the delays concentrated where they usually are.

Of 26,211 recorded runs, 603 did not run at all. Among those whose arrival reached the archive, 18,711 were within five minutes, 2,852 between five and thirty minutes down, and 299 more than half an hour — the tail that people actually remember.

“This service has been delayed by a speed restriction” was the most common explanation, given for 622 services.

Tyne and Wear Metro came closest to running to time, 97.1% of its 174 recorded arrivals; Great Northern had the largest cancelled share at 13.0%.

Friday carries the heaviest long-distance loading of the week, and it is the day on which a late-afternoon problem has the fewest spare paths to recover into.

The day in numbers

Every percentage among the bands is of the 21,862 trains whose arrival reached the archive — not of all 26,211, and the bands are exclusive. 3,746 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 3,144 runs down to TY on 4. 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 86% and 83% — why both are published, what each hides, and how the sort treats a small operator.

Why trains were late

8 different reasons were given for delay on this date, each reproduced in the operator's own words.

Why trains were cancelled

A reason reached the archive for 268 of the 603 cancellations (44.4%), across 8 distinct reasons. A run cancelled part-way along often carries no reason at all.

The longest delays

The worst of them arrived 3h 35m behind schedule — Peterborough to Horsham, booked away at 07:23, run by Thameslink. The ten longest range from 3h 35m down to 1h 37m, and they belong to 6 operators, London North Eastern Railway accounting for 3. What a delay on that scale usually means.

Through the day

Booked departures by hour, with the share that arrived within five minutes. Punctuality was weakest at 00:00, when 61% of 116 arrived within five minutes.

The filled part of each bar is the share of that hour's booked departures that arrived within five minutes. The quietest was 02:00 with 13.

What ran

Formations were recorded for 24,729 trains on this date, made up of 2,783 individual units and 12,240 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 3,021 of the day's recorded trains from a pool of 217 units.

The average train was 5.6 vehicles long. The longest formation recorded was 15 vehicles.

Of 26,211 runs, 24,729 had a formation published (94%) — these are allocations rather than observations.

Buses

17,175 buses from 183 operators were seen on this date, across 3,157,420 position reports.

134,386 bus journeys were followed to their destination on this date. 94,148 arrived on time, 7,393 late, and 32,845 — 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.

Averaged across every journey, buses arrived 0.2 minutes ahead of schedule — the early arrivals outweighing the late ones.

By operator

Of the operators with enough journeys to compare, Reading Buses ran closest to time (92%), and National Express furthest from it (33%).

Our figures, not the regulator's — why buses run early, the current league.
