Another resource for anyone modeling the C&S in HOn3 is Wayne Weiss, who runs "LocoDoc" in Salida, CO.
http://www.locodoc.comWayne is a C&S fan who has been working in HOn3 since the 1970s. He has developed micro-motor re-gearing sets with fly wheels for virtually all the HOn3 C&S models (PFM, Westside, Key, Lambert, NWSL Spartan series, etc.), as well as many older HOn3 D&RGW models. I was always amazed at how he could make an HOn3 locomotive crawl and not stall, when I would visit him at his old hobby shop in Houston, TX.
Give Wayne a call. I'm sure he knows the ins and outs of all the later Precision Scale HOn3 imports.
