What this page is. The organisation that runs the system an entry describes (transit company, fare system, bike-share platform). Membership is computed: every published entry citing a URL the registry attributes to Transport for London appears below. The classification says who publishes — never how strong the evidence is. That judgement stays on each entry, in the grade beside it.

✔ Every published entry is checked against the public sources it cites before publication.
