And Ireland? Or is the map just having a very specific interpretation of “Europe”?
I don’t know, but that’d be the point, right? If it framed Western Europe we’d know that those countries don’t have any, but cutting them off just makes it ambiguous.
I see it more like “Ireland doesn’t have night trains, so let’s focus the map on the part of Europe where they have most of them”

night trains are for long distances. Can’t really do that on an island. Night trains are basically just sleeper trains, but those connections need more than 3-4 hours of distance to make sense
