Adding international trains

[koeleboe]

As already described in another issue, vehicle data is not available for international traffic. However:

By checking the liveboard, you can see the international trains. From that, you can find the starting and ending point of the international train (for example: EUR9364 to Paris Nord.

As far as I know, these international trains are not available in the GTFS file, but you can "guess" where the train is coming from, as international trains do have specific arrival/departure points (Brussels South - Amsterdam Central - Paris Nord - Dusseldorf Hbf etc).

Based on this information you can get the vehicle data, which gives us a 'JourneyDetailRef': {'ref': '1|12456|0|80|5112023'}.

This can then be used for further purposes (finding the intermediate stops etc):

Another (possibly more robust) way of implementing this would be obtaining data directly from SNCF (TGV/Ouigo), DB (ICE) and Eurostar (Thalys/Eurostar), then querying that exact path. On the other hand, that would add another three API dependencies which can break.

As for Eurostar, there is one GTFS file, that normally doesn't change a lot according to the website. I however have had no time to check further.

I would * love * to have/restore this kind of info.
