I'm in the process of building a C&O Pullman Standard passenger train. As far as I've been able to tell only American Lightweight Car Company and Union Station Products have the correct car sides. The PRB D&RGW coach and 10-6 sleepers are identical to the C&O cars but are very pricey if you can find them. PRB was going to make the full C&O train but didn't get enough reservations.
The Union Station Products car sides are more detailed than the ALW sides especially the skirts. However the USP sells only the car sides. You still need the ALW kit to use as a core (car ends, underframe details, roof).
Here's the C&O combine built with the ALW sides.
And here's a C&O coach with the USP sides and the rest of the car from an ALW kit.
These are 3 rail cars with K-Line trucks.
