Hang on, Keith!

I've finished my HOn3 RPO 11 floor last night and I am working on the coupler mountings, finally noticed one important thing:

Linn printed a coupler draft gear "notch" in the original HOn3 car design -- remember, your Sn3 print is simply a blown up HOn3 car, so the "notch" is proportionately wider and deeper.

C&S passenger cars sat high on their trucks, usually 36" from the bottom of the floor under sheathing to the top of the rail. Couplers were mounted so the center line of the shank was 26" above the top of the rail.

The couplers on C&S passenger cars went under the end beams, not through them. This probably explains your coupler height mismatch, with your locomotive number 9.

I am planning to cover the "notch" in the endbem with a piece of thin (0.010 x 0.100) Evergreen styrene and then mount Sergent scale operating knuckle couplers under the car using an Accurail HO "scale" draft gear box. Photos to follow soon (I hope).

As to the safety rails inside the RPO windows, I can consult my "Quik-Pic" book for RPO 13 as to color tomorrow; working in the hospital today.
