For some reason, the number 82 comes to mind.....but it's been a long time since I got to wander thru the shops carte blanche like I did. 3 steamers on the NN would be nice- what also would be nice is to change that all-orange KCC painted those RSs to a scheme close to what NN had on their SD before 1983.
BTW... Also, the S-12 and the VO-1000 are still in storage, more or less, in the engine house. There are a RS-unit (I think it's ex-Magma) and a Espee SD9E in the "ore yard" that are parts sources for the operable diesels.
