Nice map for France! But it seems to include only SNCF and subsidiaries, so no RATP suburban services (RER A and RER most of B) nor partnerships operated by other companies (RENFE SNCF or DB operated by RENFE or DB).

As for Trainscanner, it looks promising, but it's a bit weird having buses show up on Trainscanner, and as the first and only option on most of the first trips in the default search (trips from Paris, today). A UX like Trainline's where it shows trains and buses in different tabs would be nicer, IMO.

For GRAOU, RATP services are currently visible. (You may need to toggle a switch on the top right.) However, it's important to note that the data source for this website is SNCF, so you won't see any competitor trains (:

Thank you so much for the feedback! I agree it would make sense to highlight the train a bit more !

Interesting. Are there open APIs that you use for train-scanner or do you have to reverse engineer some apps?

Routes and timetables are increasingly becoming openly available. However, obtaining fares data is challenging. Do you have a specific use case for such data?
