Train: Green Travel Data — Now Live
Green Travel Data, formerly Green Travel Pledge, is live for GB National Rail journeys. Send GREEN-TRAVEL-DATA; the former name still works.
What: Green Travel Data (GTD), formerly Green Travel Pledge, is now live in SQUAKE for GB National Rail journeys. The Rail Delivery Group renamed its dataset, and SQUAKE's train methodology now uses the new name.
| Methodology value | Status | |
|---|---|---|
| New name | GREEN-TRAVEL-DATA | Use this going forward |
| Former name | GREEN-TRAVEL-PLEDGE | Still accepted and calculates the same way |
Both values give the same result, so existing integrations keep working without changes.
What's included:
- Each journey is calculated with the Green Travel Data release whose timetable covers its
departure_date, or the latest release when none does.algorithm_specificsin the response names the release used. - From the timetable starting 14 December 2025, every pair of GB National Rail stations is covered, whether the journey is direct or has changes.
- Seat types stay the same:
first_class,second_classandaverage. - Client methodology settings and reports show the methodology as
GREEN-TRAVEL-DATA.
Do now: Switch to "methodology": "GREEN-TRAVEL-DATA" and keep sending CRS station codes and departure_date. Send distance_in_km if you want a figure for station pairs a release does not cover.
