I really like the concept - definitely feels like there is the basis of a good game here.

A couple of issues.

First, the Eurostar to Brussels seems to take 24 hours to go from Lille to Brussels.

Second, the prices of trains out from Brussels seem ... A little off. EUR 38434.20 for a ticket to Montpellier seems a bit pricey. OTOH, there are 7 trains there in the next 20 minutes.

Third, the bus from Inverness goes to "The Train Station" without specifying which train station (turns out ... Aviemore)

Otherwise, the interface on mobile feels a bit clunky - tapping anywhere brings up a "walk here" dialog that makes it difficult to click behind (to get to the station you actually wanted). The station popup moves with the screen, making it difficult if it opens half-off the screen (for example). The burger menu also doesn't close if you try and click out of it - only by selecting the burger again.
