The underground train in Frankfurt. So convenient, so wonderful.
What amazes me about the trains in Germany, what little I have experienced in any case, is that the train fare is virtually an honor system which everyone seems to follow. I experienced this in Switzerland too. Passengers buy their train tickets, whether it’s a one journey ticket, a day pass, or a monthly pass, and then board the train without going through a ticket checkpoint or a turnstyle, and, from what I experienced, no one is on board checking to make sure every passenger has a ticket. Amazing!
I asked my Swiss cousin about this when I was in Switzerland and she said that in her entire life (and she is probably in her late fifties) she has only been asked for a ticket once on Swiss public transport. She was surprised when it happend, but, of course, she had her ticket just as she always does.
