I just read an article about the Virginian E33 rectifiers. The Lionel version did not sell well due to it's looks. General Electric didn't put much effort into the aesthetics of the real locomotive because it was to be used for coal hauling in mountainous regions.
You can say the same about Pennsy's E44s. But I think they both had appeal. Just as Geeps did. If you look at some electric locomotives from around the world, and compare them to the E33, the E33 fairs most favorably in the looks category. GE even put that curved roof over the cab. So there was someone in the design department with alittle flair.
