>>858756We do have bunk bed sleepers in the US. However, they're only available for long distance (20+ hour) routes and Amtrak only has two styles, bedrooms that come with their own separated toilet or roomettes which come with a cleverly hidden toilet right in the room.
We don't have euro styled shared rooms because nobody would buy them, because Americans don't like sleeping with strangers beyond a coach seat.
http://www.amtrak.com/onboard-the-train-sleeping-accommodationsSleeper trains aren't that popular because the rooms and roomettes cost about as much as a first class airplane ticket while coach seats are only about $20-80 depending on the route.
>>858785I'd say they'd end in the US too, but Amtrak is pretty clear that they're committing to sleepers with the new modular Viewliner stock. I just wish that the rocky mountain states would get more money to rebuild and expand all the rail lines that pass through them to reduce bottlenecks.
