ExtreTren data and sources

Learn about the rail data sources, processing and limitations.

Timetable and route

We use Renfe's GTFS to identify services and the Extremadura stations each train serves.

Delay history

The open josernalist/renfe-gtfsrt archive captures Renfe's GTFS-Realtime feed every five minutes.

Reduced copy

Every day we keep only services that call at Extremadura stations and summarise them, keeping the website lightweight.

Today page

Today downloads the raw CSV directly for the current date; if unavailable, it uses the latest copy bundled with the site.
