I’m making this one easy as I’m under a time restraint at the moment.
The EMD SD40-2 was built from 1972 to 1986 in 4 phases.List the phases by years beginning and ending and what distinguished them.Each correct variant of each phase will be scored as 1 point.Highest score wins.
Have a good one.

I think I am a reasonably good information source on this kind of thing, but without cheating and looking this particular information up in a book or on the net, I couldn’t even begin to make a guess and get it right (and very likely nobody else will either unless they cheat). I’ll respectfully pass on this one.
Phase 1 - 1972 to 1976, “chicken wire” radiator air inlets
Phase 2 - 1976 to 1979, “corrugated” radiator air inlets
Phase 3 - 1979-1982, lengthened nose
Phase 4 - 1982-1986, new blower duct and straight frame
BTW this is from memory, dates may be close but I believe this is correct.
Silicon got 3 correct.Still looking for a lot of info tho.
