Does anyone know where I can find an electrical schematic for an R32 Master Controller?

Thanks. Bob

It's probably classified info.

But for the basics: the model is a GE SCM type 17KC76AE3. A decent photo is here.

I'm buying one, and want to interface it to interface it to my model railroad.

What do all those numbers and letters stand for? To my knowledge, the nomenclature KC7 referred to the vertical type controller used in LIRR and PRR MP54 type MU cars, New Haven's 4400 series "washboards," and today on the NJT Jersey Arrows.
