Best bet if you have a US card is either go straight to the ticket window, unless you have cash, preferably exact.
Also, as the OP may not be that familiar with the trains, it may just be easier to go to the ticket window to ensure he doesn't make a mistake. I've certainly used that method in a few places around the world!
