Tim, your model is very nice. I live in Russia (and used to live in SU
before). When I was a student, I travelled with these trains a lot. Since
Russian is my native language I can help you to translate something to
English with a pleasure - just let me know, what do you need :)
I’m not a big train fan, so I do not know what “EMU” stands for.

EMU - Electric Multiple Unit
DMU - Diesel Multiple Unit
These terms are not commonly used in the US I don’t think(1). But the idea is
that the train isn’t “locomotive hauled” but rather more than one of the “cars”
has a power truck, either straight electric or Diesel Electric or Diesel
Hydraulic or whatever. Some cars may be “trailers” though, I think
The most common DMU in the US was the Budd RDC (literally Rail Diesel Car)
although there were others. Sometimes these ran as a single unit though,
although they were built to be MU-able
What I don’t quite get with the EMU designation is what’s the difference between
an EMU and say, a string of subway cars or interurban cars (like what South
Shore Line runs, saw some in Gary on my way into Chicago this morning)... those
have traction motors in each (or at least many of the) truck(s) too.
Perhaps some european can answer that one?
1 - Although “MU” is... it is just the term for connecting two or more
powered(1) cars or locos together so they can be controlled from one control
position.
2 - technically not necessarily even powered, actually. In push pull service,
all the cars have MU cables running down them so that the unpowered last car can
control the locomotive when running in push mode.
