Does anyone know what colors PRR painted wooden structures(stations, wayside buildings) in the 1945-1955 period?
Well an easy and not an easy question to answer. The specified color was very close to Floquil Depot Buff with dark brown trim BUT inidiviual locations particularly the farther from Philly got whatever the maintenance people had on hand. SO if you want a building that would be a Philadelphia approved version go with these colors. If you are modeling a particular building in a particular town or city you will have to find out from a local source what color it was.
We used to call the colors “Chocolate and Vanilla”.
