Over the last many years I've been building a fairly prototypical early 1950's C&O passenger train. The cars are somewhat unique as they were built by Pullman-Standard with fluting applied only below the windows and no three rail manufacturer makes them (there are Railking versions but they're not scale length). The last one I've built is a 5 double bedroom/buffet/lounge/blunt end observation using an old American Lightweight Car Company kit for the core model and car sides from Union Station Products.
This was a fairly involved project and isn't for everybody so I'm wondering if you scale guys are interested in how to build something like this. I have construction pictures I can post.
Of course I had to include a detailed interior and basic underframe.
A little history on the car - After WWII the C&O ordered eight of these cars which did not arrive until mid-1950. The railroad quickly decided they ordered way more then needed and four were immediately sold to the B&O without ever operating on the C&O. Later one was converted to an office car (currently located at the C&O Historical Society at Clifton Forge, VA). The three that were left operated as built until the early 1960's when all were converted to diner/dormitories. The lounge area was converted to a dining room, the bedrooms to crew accommodations, and the kitchen upgraded. Apparently the lounge was a money loser as the chief revenue source would have been serving alcoholic drinks and the trains ran through mostly dry states.
