As The Local recently reported, it is a definite ‘no-no’ to place your luggage on a seat next to you on a crowded train, where passengers are looking for vacant seats. While placing your bags on an an empty seat of a crowded train is a blatant violation of common courtesy in many countries, this next one is implicitly Swiss — because Swiss people like to regulate pretty much everything, even if it makes no sense whatsoever to people from outside the country. You must purchase your ticket before you board your train; if you do it later, or after the train departs, you will be fined.
