>there are at least three different interfaces/machine styles

Yes!! This drove me nuts.

Not only are there different UIs, but the physical UX differed sometimes too! I really, really want to know who's idea it was to implement the rollbar they have on the machines, because that absolutely does not work well. And the fact it rolled on one machine up and down, and on the next it's reversed??

I hate buying mobile tickets but sometimes it's just so much more convenient.
