Hi DJ & Will,
"Eight different car types were ordered: baggage-RPO, baggage-dormitory, two chair configurations (52&58 seat), dining car, two sleeper configurations (10-6, 1MR-2DR-lounge), and boattail sleeper-lounge observation car."
The 1MR-2DR-lounge that I mentioned above is the "Crescent" series cars. there were 4 of them:
#2350 Crescent City, #2351 Crescent Harbor, #2352 Crescent Moon, & #2353 Crescent Shores.
I have copies of the car diagrams that I would be glad to share with you. Just email me. My email is in my profile.
Tom
