Hmm, if those red lines are meant to be rail lines than someone's definitely made some errors. E.g. the Europe map shows a red line in Iceland, perhaps between Reykjavík and Akureyri. But there's no railway between Reykjavík and Akureyri and in fact there's no rail in Iceland at all.

I just assumed the red lines were "major routes" of some sort, maybe rail, maybe roads.
