ATTN.South Park fans,,,help,please.

Yeah, I've asked before..any good guesses on the color scheme of DSP&P Mason Bogie #15, the "Breckenridge"? I know some of this is conjecture, but I am guessing the jacket was Russia Iron blue, domes deep red, possibly with blue dome tops and white stars and striping. I am guessing the cab was light blue and the tender tank greeen or brown, with red faring. Lettering was white or light yellow with red shadowbox. No idea what the drivers or trucks were painted. I have a commission for this unit clbing eastward on the Palisades. I plan to put a reefer, two boxes and a way car. Any ideas educated guesses or observations? Fire away...
