Day by day

Each bar is one calendar day, measured the same way the headline is. A month reported as a single percentage cannot tell you whether it was uniformly average or fine except for one bad week.

Bars are scaled between 64% and 86%. Weekend days are marked; they carry less service and usually read higher. The thin line under each bar is how much of that day this site actually measured, against the best-measured day of the month. A short line means the percentage above it rests on far less.

What should change

Worked out from this month’s arrivals, ranked by how much service each problem affects. Each line says what is wrong, when, and who can fix it.

The diagnosis for this month has not been published yet. It is produced once, when the month closes, because it re-reads every arrival in the month.

Not covered here

• Whether scheduled trips actually ran. Measured over a rolling recent window that cannot be reconstructed for a closed month.
• Whether frequent routes arrive evenly or in groups. Measured the same way, over the same rolling window.

Against other months

Furthest from the timetable in September 2026

The routes with the lowest share of on-time arrivals. A low figure does not say whose fault it is: a route can be late because its timetable is wrong, because the service is failing, or because of the traffic it runs in. Each route page separates those.

Measured, but not for enough of the month

These routes ran on fewer than half the days this month was measured. Their arrivals count toward the network figure above, and they are kept out of the rankings because a route present for part of the month is not competing with one that ran all of it.
