As an aside, I’m lucky enough to have a reclining coach seat from an SP car in my trainroom. This inspires me to try a bit harder to get all the train boxes off of it and actually sit in it once more.
After lots and lots of searching, internet and other sources, I found these at a movie prop warehouse in Van Nuys, CA. They had these for a long time and can’t remember exactly how they were obtained. But the story was they came from a gutted Amtrak car in the early 1970s.
The room is so beautiful that I hesitate to say anything at all. My only thought is that some large photos could be set on the right wall, depicting New Mexico scenery, positioned so that they look like windows.
