I've got 3 Williams F-3's, 2 geeps, an FA, and an NW switcher. I re-wired all to series. They are excellent runners. I have no idea why they come wired in parallel.
When I see a set of AMT/KMT set of F-7's come up on e-bay, and see what they sell for, I think I should sell. Prices aren't going to get higher in the future. On the other hand, they were quality-built toys from an era I like, and they are different. I remember a Williams ad in Model Railroader from the early or mid-80's offering these engines with the same Santa Fe paint scheme. Does anyone else remember these ads, and more importantly, has anyone ever seen one?
