I am always wondering which organization regulates the european railways (e.g. ticket sale, routing, fare computation for international journeys and rail passes like interrail)?
Many European countries (inc. those out of EU countries like BiH) have the similar ticket stocks. Anyone knows the origin and/or (official/unofficial) documents on this? Also when I travelled on international trains between some eastern european countries (e.g. between Croatia and BiH), the staff stapled the tickets into booklets which also share the same pattern (sorry, cannot find a photo at the moment).
I cannot find much useful information using google or wikipedia :(
e.g. when using wikipedia search for interrail pass, I cannot find any information about who is behind this unified program.
Thanks!
