Transport for London
Arrivals, status, Explorer identifiers, and Board displays use the Unified API through tfl-ts, plus station-data GTFS for hubs and platforms. Transport for London publishes that data under TfL Open Data. Required wording: Powered by TfL Open Data. Contains OS data © Crown copyright and database rights.
Public examples on this site may use the project key with a short server cache. A personal Board should use your own key. Stale or sample data is labelled when a refresh fails.
Station names mixed into geographic bundles are the same TfL Open Data. © Transport for London · station metadata where present.
OpenStreetMap
Geographic maps and line topology draw London transit route geometry from OpenStreetMap contributors, simplified here into unique track. That data is not live arrivals. Licence: ODbL 1.0. © OpenStreetMap contributors · track geometry · ODbL.
Unique-track map layers (merged centreline, dual directional tracks, welded junction graph) derived from ssh.ldn Overpass cache. Full route variants stay under data/geography for non-map use.
OpenFreeMap and OpenMapTiles
Geographic, cycle-hire, and Explorer maps sit on vector Positron and dark styles from OpenFreeMap and OpenMapTiles, with OpenStreetMap data underneath. No API key. © OpenStreetMap contributors · © OpenFreeMap.
Track geometry origin notes are in the repo at data/geography/ORIGIN.md. Brand limits are on Licensing and brand use.
