We took a train from Florence to Prato and then Prato to Lucca. Prato is really very interesting by the way with its Castello d. Imperatore.
And I was watching the other passengers. A few people that looked local, bought tickets, at the machines, and had them punched, but the vast majority of passengers didn't seem to do any thing other than get on and get off. I did notice that these other people all had cell phones and used them. Is that it? Can they buy the ticket with their cell phone and then show a confirmation screen to the conductor if asked?
The buses are a different story. I never saw a single non-tourist ever punch a ticket or show a bus pass of any kind. I'm assuming that this is some sort of bus pass honor system and that they show the pass only if asked to.
I'm just curious since this is so very different than any US public transportation system whereby EVERYONE shows the driver a pass or pays on the bus, unless its a Free Ride zone like Seattle. And the Italian Public Transportation system is kind of a thing of beauty once you figure out its little quirks.
