Train Mountain RR Museum in Oregon is essentially a huge 1/8-size live steam operation, but there are several pieces of 1:1 scale rolling stock under restoration also, including former NYC and CN Pullmans, and several cabooses, including a modern steel wide-cupola model that the Rutland Railway owned briefly. Rob Davis posted this link on another discussion group, so I'm relaying it here.

As was mentioned in the other thread, there is only one ex-CN, exx-NYC sleeper. The pictures on the website don't make it clear that they're all of the same sleeper at different times.
