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.
