This website would be nothing without some useful third-party open data sources.
Data for Great Britain is licensed under version 3 of the Open Government License:
- The National Public Transport Gazetteer
- The National Public Transport Access Node database
- The National Operator Codes database

I also use TFL open data and Transport API.
Data for Northern Ireland comes from Translink.
Data for Ireland is from Transport for Ireland.
