Timetable period 2025
The published figure is the most recently completed timetable period. The current one is below it as a trend — month by month, and never folded into a single figure: nothing is averaged across a timetable change.
December 8, 2024 – December 13, 2025

Trend — Timetable period 2026
The current timetable period, month by month. Each month is counted on its own; these rows do not add up to the figure above and are not meant to.

Every row carries its own coverage. A month below the floor publishes no share — the three columns on the right still say why.
Not measured yet — these months are after the archive's most recent one: October 2026, November 2026
By hour of day
When an hour starts decides more about punctuality than almost anything else measured here.
Over the last 365 days in the archive, not the timetable year above — so the grid shows the hours as they run now.
October 1, 2025 – September 30, 2026

The outlined cell is that day’s worst hour — it is not the same hour on every day.
Service day, not calendar day: hour 24 is 00:00–00:59 the following morning and still belongs to the day before.
An hour's coverage is the measurement axis alone. The figure at the top of this page takes the worst of three axes — days, journeys, measurements — and so rests on more evidence than these rows do.

The line registry is built from one week of June 2026. Lines that did not run in that week have no name here — they are measured all the same.
Source and method
Source of the measurements: opentransportdata.swiss (istdaten). How we measure is written up in the methodology.
A figure is published only from 90% coverage upward. Below it there is no figure here — not a greyed-out one, not a dash, none.
