Daily performance archive: trains and buses

One page per day, recording what the railway actually did — how many passenger trains ran, how many arrived on time, how many were cancelled and why — and, below the rail figures, how the buses ran by operator.

The industry's live feeds are not an archive. Darwin and TRUST retain roughly 30 hours of detail and then discard it — ask either of them what happened three days ago and there is nothing to answer with. This section exists because the data was captured as it arrived.

There are 94 days here, covering 2,333,642 recorded passenger services, of which 52,568 (2.3%) were cancelled.

Buses on the same pages

Each day's page closes with a section on the buses: how many vehicles were seen and from how many operators, and — from mid-August 2026, when recording began — how punctual each operator's journeys were, with early running counted separately rather than as on time. Pick a date below and scroll to Buses. The same figures cut by operator rather than by date are on the bus operator pages, and today's live picture is bus punctuality. Which dates get a page is decided by the rail archive alone, so the two networks never disagree about what exists.

Every recorded day

Newest first. “On time” means arrival at the destination within five minutes — a stricter test than the industry's own public measure — and it is a share of the arrivals actually recorded that day, not of every train that ran. “Incl. cancelled” is the same count over a denominator that also holds the cancellations, which is what the industry's measure does. “Recorded” is the share of the trains that ran whose arrival we captured, so two days can be compared fairly: a fall in Trains is the timetable, a fall in Recorded is a gap in the feed.

A dash means arrival times were captured for too little of that day to state a punctuality figure; the Recorded column shows how little. Those pages still record what ran, what was cancelled and why.

What is counted

Passenger services only, and only runs that settled — arrived, or were cancelled, or went more than two hours past their booked arrival without reporting. Delay is measured at the destination rather than at intermediate timing points, so these numbers read slightly worse than the published industry figures and should not be compared with them directly.

Freight is not included: it is roughly an eighth of the trains on the network, but Darwin does not cover it, so counting it would mean counting something different from one day to the next. Where the data comes from sets out every feed behind this.

Why this archive exists at all

The live feeds are not an archive and were never meant to be one. They retain roughly thirty hours, after which a day is simply gone — there is no query that recovers it and no back-fill that reconstructs it. Everything here exists because it was written down as it happened.

That has a consequence worth stating plainly: the record starts on the day recording started, and any gap in it is permanent. Two retention windows run in parallel — day summaries are kept for 400 days, while the per-stop detail behind them is pruned at 14. An older date therefore legitimately has an outcome without the calling-point times that produced it.

Percentages are of measured arrivals, never of runs

This is the single most important thing to know about these figures. A run can be recorded as having happened with nothing said about when it arrived, and such a run counts toward the day's total while counting toward no punctuality band at all.

Dividing on-time by every run would therefore have published sentences like “0.9% of trains arrived within five minutes” about an entirely ordinary Wednesday. So every percentage here is against arrivals we actually measured, and each page states how many that was. Where coverage falls below half, the page reports no punctuality figure at all and leads on what ran and what was cancelled instead — a real state that the earliest dates in this archive will always be in.

Cancellations are the exception and are trustworthy throughout, including on the thin days: reason coverage runs between 78% and 100%, in the industry's own words. The methodology sets out how each figure is built, and how a delay is measured explains why three feeds describe the same late train differently.

Which dates get a page

Only complete days, and never today. A day in progress is a running total — at midday the archive holds about a third of its trains, and a page built from that would report the third as the day's traffic, plausibly and wrongly.

Dates carrying fewer than a thousand recorded runs are also left out. That is not a judgement about the railway: a weekday runs around 26,000 services and a Sunday around 16,500, so anything below a thousand means collection was interrupted rather than that the network was quiet.
