Well, the new detroits are 4stroke...in fact now detroit is part of Mercedes Benz, but that's off topic.
The 2 strokes operate at normal diesel speeds (around 1800-2300rpm). They don't really rev any higher. EMD (GM locomotive engines and tug boat engines) are also 2stroke.
The reason the 2 stroke DD's are gone is cause that basica engine design is 60 years old. It was just going to cost too damn much to get the emissions of the 2 strokes down. they also aren't as fuel efficient (overall). And the screaming D's like to puff out blue smoke.
Basically, it's old technology and time to move on (except in HUGE applicatoins ).
