QUOTE: Originally posted by CSSHEGEWISCH The sound was generally similar to the smaller 645 engines and as a whole, 645 and 567 engines were not that different in sound. Both were 2-cycle engines and both had a 10" stroke. The only other EMD model with a V-20 engine besides the members of the SD45 family was the SD80MAC, which had a V-20 710 engine.
QUOTE: Originally posted by trainboyH16-44 I think that the SD50 was the most poweful 645, or was it just short? Can someone remind me? Matthew

QUOTE: Originally posted by electro-ortcele Are these the peak of the 645 line (not counting those 2-engine DD locos) in terms of power and size? And is it true that 20-645 was an 4-stroke engine? If that is so, how do these things sound?
QUOTE: Originally posted by electro-ortcele BY the way, how do you "rate" a prime mover to higher HP? Isn't its HP determined by fixed things like size of cylinders, number of cylinders, max RPM etc etc? What do they change in it to get say 4200hp from standard 3600?

QUOTE: Originally posted by electro-ortcele ok, then this is settled, thanks and what about the sound, how similar does it sound to 12-645E3 and 16-645E3?

QUOTE: Originally posted by broncoman Since we are on the subject, does anyone know if they ever de-turboed a 20-645 for railroad use (like what UP is doing to many of its old SD40-2s for yard service)? I know that UP derated the SD50s, did any of the other roads that ended up with them do the same? Dave
