I had the same problem - you have to select INTERNATIONAL in the drop down menu!
Other than that it was fine, so much easier than our systems!
That works, but how do I get the tickets? I have to choose either US Mail or express delivery, neither of which works outside the US (to the UK). There seems to be no option to collect the tickets at a station (at least for my chosen journey in two months' time).
No problem. There is an option to collect the tickets at the station. Print out the online ticket confirmation page with the barcode on it and the return email that you wil receive. You are already ticketed so just take the confirmation with you. Scan it on the ticketing machine at the terminal and your tickets just pop out or give it to a clerk and they will issue your tickets. We never have tickets mailed as they can get lost. Also if you do not opt for the hard tickets, you can follow the rates online. If they should drop you can call and ask for the lower fare. You cannot get a fare adjustment once the tickets are in your possession.
If going on any trip 900 miles or more with overnight travel, I strongly suggest going in a sleeper. The privacy and bed is a welcome comfort in the evening hours and the dinners that are included and served in the dining car are actually very good. The lounge serves typical cocktails , beer wine and soda and is a good place to congregate with your fellow travelers.
Our entire rail system over here may not be up to European standards but it does get you to your destination in comfort
