alt Hacker NewsIs the interesting part the upvotes, meaning there's more people interested in UK train networks than French ones ? And it's a comment on demographics ?
Or is the interesting part that the UK one is real-time, and the French one isn't (or at least, zooming in, I don't see them moving).
It may simply be that the language of HN is English, so more people here are, in fact, interested in UK train networks. The moving bits on this site are guesstimated based on schedules and delays and not based on real position information.
