The Lionel locomotives are the wrong color. They are blue or blue-ish. The road
did not have light blue locos, but the L&N did indeed use a Confederate gray; the gray and yellow were meant to echo the uniforms of the army of the CSA. I considered a Lionel L&N GP-9 briefly, as I remember the paint scheme quite well. But, not being a diesel guy so much, and not being a GM diesel guy so much, that wrong color put the nail in the coffin.
Weaver, though, gets the L&N Confederate gray right (maybe since Weaver is located not TOO awfully far from Gettysburg...?).
I hated to pass it up, really; I always like to support the production of items relating to my native South.
