Fun loophole with those minimum transfer times, was it patched since? It's not something I would use; I don't mind paying a fair price for what is a form of transport much more sustainable than air travel, although I do like to figure out economically frugal routes.
Having to have an argument with a conductor isn't my idea of leisurely travel either. I could manage in Germany, but I once had an Italian train conductor who didn't understand the (valid and very popular) Interrail tickets we had and just got annoyed. She gave up thankfully and move on in a huff.
