I've never been on a British train, but I'd imagine they're just like the trains in New York, and in that case, they're so fun.

Here, you can buy a ticket at a booth, or you can use a kind of touch-screen ATM sort of machine where you put in what kind of ticket you want, one way or round trip, how many people, etc, which is pretty easy. Then you board on and relax until they call your stop. And even if you have your iPod in or something, it's no matter here (and I would imagine there too), because they have a big screen in the front that says the stop. And of course, you feel the train stopping. :]

The subway here is quite a bit harder. It makes me feel like a total tourist nub. :[
