Elizabeth line

93% of Elizabeth line's 24,635 recorded arrivals from 6 Aug 2026 to 23 Sept 2026 were within five minutes, putting it 5.3 points clear of the network average for the same dates.

Over 49 archived days that is 666 services a day, 2.7% of the national timetable. Of 24,635 recorded arrivals, 22,830 were within five minutes and 48 were more than half an hour down.

Volume moved between 497 services on Sunday, 6 September 2026 and 757 on Saturday, 5 September 2026.

The average delay at destination was 0 minutes. The worst single arrival recorded was 4h 58m behind schedule, Abbey Wood to Heathrow Airport T4 on Friday, 28 August 2026.

The day-to-day spread is wide — 23 points between its best day, Sunday, 23 August 2026 at 99%, and its worst, Monday, 7 September 2026 at 76%.

1,337 services were cancelled, 4.1% of everything booked — above the 2.4% the network cancelled over the same dates. The worst single day was Sunday, 13 September 2026, at 22% of that day's timetable.

Counting those cancellations as failures, the way the industry's own measure does, takes the on-time share from 93% of recorded arrivals to 88% of everything booked whose outcome is known — 4.8 points.

Ranked on on-time share of recorded arrivals against the 30 operators with enough of them to compare, Elizabeth line comes ninth.

Elizabeth line in numbers

Every percentage among the bands is of the 24,635 services whose arrival reached the archive, not of all 32,615, and the bands are exclusive. 6,643 ran without an arrival being recorded, and nothing is claimed about those. The row counting cancellations is those same 22,830 on-time arrivals over a denominator that also holds the 1,337 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.
