Going through my collection in more detail and ran across more photos.
In what could be the worst example of a Santa Fe Locomotive ever is this Model Power HO E7 that was built by Roco. Not a bad example of an E7, but a really poor execution of the Warbonnet on a locomotive the Santa Fe never purchased. They settled on 4 axle units after the war due to grades and the only reason they ended up with E8s was that they were remanufactured from the original E1s to serve the Chicago to Texas routes that were relatively flat grades.
While K-Line calls this an F7B, it is really a Phase IV F3B. The tell is the slotted vents where a fan would occur on an F7.
Yes, I too have a Menards FP7 which was never rostered by the Santa Fe. As a beta tester my unit came with many problems that I won't get into here. I'll simply state that I have replacement parts to upgrade this and will add some details for a post 1955 Santa Fe diesel to make it a good working part of my Santa Fe collection. It will pair nicely with my F3B.
A few cars currently in the box, but I sure do love Atlas cars. Plug door boxcar and a covered hopper.
