Not only unpopular, but pretty daft too. If you think the basics of a language should include "this train will separate into two at station X, please sit in the front Y carriages to get to Z" then enjoy doing a cross-Europe trip.
This kind of thing captures older adults who know everything and have never heard of a trainset split.
I made a similar mistake years ago in NY - I assumed that the impressive subway system could get me to the airport, but you transfer onto a bus that gives you a VERY detailed tour of some neighborhoods.
I would have mentioned running away at age 13 with no destination in mind but I never left the country.
