Lionel has a set of heavyweight PRR passenger cars that do not have the gold striping normally associated with PRR passenger cars (see picture). I've searched the web and the very few pictures I could find of this paint scheme were in old black and white pictures, indicating this scheme was used before WWII. Pictures with E7s/Sharks/post-WWII locomotives had the gold stripes. Did this paint scheme (no stripes) survive into the post-WWII era? If so, would you have seen them on the main line or only on secondary tracks (locals/commuters). I'm thinking of getting a coach to add to the late 1940s accommodation train I'm putting together. Thanks for the help.
