So regarding the crescent here’s what I found from the web regarding the sleeper/ kitchen & sleeper/lounge:
http://www.wataugavalleynrhs.org/crescentharbor.php
The sleeper/ kitchen and sleeper/ lounge cars are actually 1 car..... a sleeper lounge with a small kitchen inside the car. (There were two. “crescent moon” & “crescent harbor”)
The 14 roomette is actually a 14 roomette/ 4 double bedroom sleeper. Seems like the correct 8-car consist would be:
1: RPO/ baggage
2: Baggage/Dorm
3: 52 seat coach
4: 14-4 sleeper
5: sleeper/kitchen/ lounge
6: 48 seat Diner
7: 10-6 sleeper
8: sleeper/ observation
pool service cars would be 10-6 sleepers from PRR, L&N, A&WP, & W of A.
also seems like extra coaches, 10-6, & 14-4 sleepers would be appropriate.
hopefully this gets us closer, please correct any errors.
