Re: Train Order Stand/Rack at North Clinton, MO
Keith, that would certainly explain the absence of a middle "hoop." I think this would be an interesting detail to model, especially for the transition/diesel era modeler.
I'm guessing that the top "hoop" would have been appropriate for most steam power, too, and that the middle "hoop" would have made its appearance simultaneously with the Frisco's first-generation, non-F unit diesels (e.g. GP-7, RS-1, etc.).
Bill, I thoroughly enjoy the stories, insight and background from a Frisco hand.
