@lee drennen : Lee really neat Alco freight cab unit...I saw on another thread how you made this one and it looks great. Fabulous pictures everyone, GG1Guy that is quite a display ... but where are the GG1's??
Here are a couple of Santa Fe switchers for you all:
Here is the Marx 1998 Alco S3 switcher made between 1955 and 1962 in two color schemes. First the more common maroon and yellow, shown here with a MOPAC (note lee!) cattle car and an empty auto rack.
Here is the same locomotive in the much less common but likely more prototypical black and white livery.
