With SNCB killing Go Pass and RailPass soon it is interesting to look back at the past to have some nostalgia about train tickets. Today even #CrossBorderRail
BeNeLux has been strong, but today tariff borders between the 3 tiny nations are real (unless you go to Athus no borders there).
In the 1980s we have a touristic season pass. "Tourrail"! 8 days in a 16 day period free travel in the whole BeNeLux! Yup 3 countries!
