All,
Attempting to figure out ALCO Series Locomotives, where would The ALCO RS-1 ,RS-2 , RS-3 , RSD-1 , RSD-4, RSD-5 and the MRS-1 run in the RS Series ?

Off the top of my head: The RS-1 was first produced just before WW2 (in the Pacific theatre) and was a stretched S-2 with road trucks and a short hood for a steam generator. It had a 6 cylinder 539 turbocharged prime mover. During the war, many RS-1's were requisitioned by the military and received modified cabs and adjustable gauge 3 axle trucks for use overseas. These were classified RSD-1.
The RS-2 was a post war road switcher in it's own right with a 1500hp 244 engine. This evolved into the 1600hp RS-3 which lasted to the mid-1950's. The RSC-2 was an A1A-A1A trucked version of the RS-3, while the RSD4/5 were C-C trucked versions of the RS-3.
The MRS-1 was a special design built for the military in the early 50's. It had a 1600hp 244 engine, on a "C" trucked frame. The bodywork resembled an RS-1 with a low profile export style cab.
Just a note on the designation of the Alco prime movers. The first number refers to the cylinder specs, while the last 2 numbers are from the year the model first tested. So a 539 engine was from 1939, a 244 from 1944 and the popular 251 was from 1951.
Although Wikipedia isn't always 100% reliable, there is some good info there. Makes good reading.

Steve and All,
As I am progressing with this project I came across the Drawings of MLW's RSC-24 it looks Like MLW Pint-Sized the MLW RSC -13. On the MLW RSC24 the carbody Looks to be of the MLW S SERIES, I am curious as to which MLW S Series would lend itself to such a fabrication?

A Briggs RS-23 in N-Scale would provide most of the structure for the bodywork. The chassis would be another story. I'd have to do some measuring, but the Atlas-Kato RSD trucks can potentially be squeezed into a Kato Japanese Centre cab switcher, the one ConCor sold many years ago. Might work, more study needed.
