In my previous post, I mentioned I had hoped one day Lionel would offer any Soo Line steamer with Legacy, as in "Legacy control". I also did a quick search for some images of a prototype. The description in the Lionel 2018 C2 book states the locomotives are shown in a USRA design with other railroads using a mountain design later on. Anyway, here's an image I found of a Soo Line 4-8-2.
