This is a model of a passenger unit of the Seaboard Air Line from the 1950s. This is basically the scheme that replaced the Orange Blossom scheme from the 1930s. The white colour should actually be a really light mint, but in almost any color photo from the era, it appears white. I kept the basic Super Chief shape for the nose because I think it is good enough for 6 wide trains.
I'm probably not going to do much more with this one as it is a little late for for the era I am aiming for (30s - 40s), but it's still an interesting paint scheme.
