The truck sideframes on diesels offered in 2- and 3-rail versions protrude sideways too far because the 3-rail wheel width is so big. It would be better if, as with their 2-rail freight car trucks, at least Atlas would have an alternative mounting arrangement for 2-rail diesel sideframes.
I have a couple of Lionel diesels (CN Dash-8 and U30C) on which I've mounted dummy 2-rail wheels. At some time in the distant future I expect I'll be unable to resist drilling holes and trimming tabs to get the frames and brake-shoes to line up better with the thin wheel treads. If I get used to the annoying 3-rail way of mounting long-hood handrails so that rough handling by 5(?)-year olds doesn't demand them, I'll see if I can get the gears back on my dummy axles or admit defeat and get the box of Central and Weaver gearbox odds and ends out.
