Real cool, thanks for the link! Wish we had something similar for our national railway network here in neighboring Romania. And one good thing that will be brought by us (Romania) finally getting into Schengen this year (God- and Austria-permit) would be that the rail connections between Romania and Hungary would become much more common, especially the regional ones. I can see a Salonta - Békéscsaba ride on this map…
The aim from March is for air and maritime travel to be part of Schengen, terrestrial not yet unfortunately.
