There was a diner in downtown Aberdeen, MD that I'm not sure was a RR car, but it looked like one. The pace was a 50s-60s time capsule, and I loved eating there when I was still stationed at the Proving Ground.
There was a neat restaurant at Vancouver, WA just inside the insanely-busy wye where the old SP&S met the old NP. They had several RR passenger cars and a hack connected to the building. Sadly, it was out of business the first time I ever saw the place and the cars were scrapped a couple of years later. The hack, I heard, got saved by someone. The other cars are on the other side and the tracks are to the right. It would have been an amazing place to eat and watch trains but I heard it was pricey and the food wasn't very good.
My all-time favorite, though, would have to be another long-closed-before-I-got-there one, the Tweetsie Diner in Newland, NC. Sadly, this burned to the ground in a fire a few years after this photo was taken with my in it, I think circa 1982:
Sadly, this was former ET&WNC coach 23, the last surviving coach from the old Tweetsie...
