Trainline is currently only selling regular tickets and tickets for holders of a Swiss Half Fare Card. The Rail Europe link from my previous post works fine in general, although for this particular trip it didn't provide any discount when I tried it. Possibly because the Swiss leg is relatively short.
I'd stick to the two section method: buy a regular (non-discounted) ticket from St. Margrethen (border) to Passau from any of the websites listed here: www.myswissalps.com/tr aintickets/germany/pri ce. You don't need anything for the Swiss leg, not a seat reservation either. Just board your train and show the Swiss Travel Pass when requested. You're not guaranteed a seat, but in reality that's no issue. The train will start in Chur, it won't be so full that you can't even board.
