The Wikipedia article on the GE Genesis series makes brief mention of a competing locomotive design by EMD... Was this an early version of what became the F59PHI, or was it something else entirely?
Interesting! Down in the article it mentions that the GE had four-stroke engines versus EMD's Two-stroke engines. If you hover over two-stroke, you get a picture of what looks like a radial aircraft engine, only it is a two-stroke Diesel! I had no idea engines like that ever existed!
If you click on the two stroke link you will get the caption to that photo - Nordberg two-stroke radial diesel engine formerly used in a pumping station at Lake Okeechobee.
