My internal prototype freak is yelling at me, so does anyone have an idea on what colors of paint to use for the interiors of Santa Fe's sleepers? And can they be brushed on? I don't have an airbrush, and I have no plans on getting one, so any pointers are greatly appreciated.
When they're done, I'll most likely put pictures up.
You didn't specify if you want a named train, or whether heavyweight or streamlines, or the era and son on.This thread from some years back may get your started - Super Chief interior colors. Caution - some links in that thread may be dead/moved/behind a paywall. Some links still work - here's the Super Chief brouchure with color illustrations.
