Night train advocacy group Back on Track has a map showing the current network of European night trains offered by various train operators. It’s colour coded by operator, but individual lines are a bit hard to follow, and using various dashed lines for both less-than-daily service and forthcoming service is a bit confusing. Then again, given the sharp uptick of night train services being offered, it’s almost unavoidable that any map of this sort will be a bit of a jumble: compare with Jug Cerović’s version (previously) to see what I mean.
