Page 40 of new Lionel 2019 catalog, note the color scheme of the C&NW units and its similarity to the Alco demonstrators also listed in this catalog. It is correct for the units from the time CNW bought the Alco demonstrator set in the early 1950s, and minimally modified the scheme to get them in service quickly, until they were finally painted to the usual yellow and green in 1958, then retired in 1962. So this scheme reflects the mid-50s, and provides an interesting variation if you're a CNW fan. They were used all over Wisconsin, and occasionally showed up in the Chicago area at Proviso Yard. You could imagine them hauling a car ferry train from Manitowoc WI all the way south to the St. Louis area, or a long all-rail iron ore train from upper peninsula Michigan.

Weaver did these FAs in this scheme years ago, with a problematic horizontal motor tower drive (upper drive gears nearly all cracked) and later low cost rebuild program to dual motors, but those won't run on Legacy or BlueTooth! Nice conventional power locos now. They are about to become display units, here, I'm afraid.
