A quick key for EL classifications, in general order of how they appear:

M = multiple-unit equipped 

Unit's function:
F = freight locomotive (usually referring to a road unit)
P = passenger locomotive
S = switching locomotive (usually referring to a switcher)
FS = freight/switching locomotive (usually a "roadswitcher" like an RS3 or
GP7)
C = commuter locomotive (used only on U34CHs)

Builder:
E = EMD
G = GE
A = Alco
FM = Fairbanks Morse
B = Baldwin
L = Lima

Horsepower:
Specified in hundreds, rounded off to the nearest hundred
D = dynamic brakes

Additional stuff at end:
6 = 26L brake stand
4 = 24L brake stand
8 = ?? brake stand (only seen on U34CH's)
A, B, C... = Variant of major class (SDP45s were MFE-36D-6A, while SD45s
were MFE-36D-6)


I think that pretty much covers it all (hopefully, this is off the top of my
head - please add/correct if you spot any mistakes)

One anomaly: U34CH's were "MCPG-33-8" - odd, since the usable horsepower of
U34CH's is 3430, not 3300?

Not all the time - the EL used their NW/SW switchers for locals out of
Croxton as well.

And many roads (the P&LE comes to mind since I just saw photos of these in
Steve Timko's new book) used them in multiple for yard hump shoving and mine
runs (LV and Montour come to mind)
