Starting point for HO N&W SD40

[NW Modeling List]

Hi Jim; 

I need to correct you. One of Kato's first USA diesels was a SD40; their SD40-2 came much later. Rail Power Products offered a SD40 (and SD38) shell, after Athearn bought them out, Athearn offered a ready to roll SD40. This was many years after Athearn first offered a SD40-2. 

Mehano has built a SD40 model for decades, first imported by AHM, later IHC. I would not use it as a starting point. The chassis actually runs well - with a motor replacement, but is geared 8.5:1 (uses 17 tooth gear with a double lead worm). The Mabuchi motor Mantua used in their GP20 and F7 in the 1990's is a very good match for that gearing.

Depends on what you want in a chassis. Athearn or Kato? Or even IHC? However, as I remember, the Athearn is a "Dash 2," and the Kato probably is as well. I think the IHC is a "regular" SD40, but it will give you some other issues to deal with, such as handrails and coupler mounts. (but the shell separated from the walkway casting will make hi nosing easier) Remember, N&W had "Dash 2's" as well. For all around detail and economy, I would recommend the Athearn. For overall quality (regardless of price), go with the Kato.

I’m not finding any N&W SD40’s out there for sale so it looks like I’ll have to make my own. 
Which model when stripped of paint, converted to high hood, and painted would be the best starting point for an N&W SD40?
