Those would be great for HO-scale Athearn SD40-2's also. Maybe they'll have
them in HO?

I've been working with CESM too.  We've been trying to bring N&W's triple
clasp HTC trucks as found on SD40-2 to N Scale.  They're designed to fit
Kato SD40-2s.  They should be ready for release soon.


Didn't N&W's Trainmasters also get the same vents as RS-11s?

My name is Blane and this is my first post in this email discussion group
about N&W modeling. Today I have a product to share with you that has been
missing until very recently.

The story began with a pair of "NW" RS-11s from Atlas dating back to
mid-2000s. When I decided a year or two ago to keep their factory paint and
make them more prototypically accurate, I discovered a body modification.
All N&W purchased RS-11s had shutters/vents added over the air intakes at
some point in the early 60s. I searched Walthers and other places for
possible solutions, but couldn't come up with any leads.

A month or so ago, I came across a company called Cutting Edge Scale Models.
They happened to make these vents/shutters in N scale and I inquired about
them being produced in HO scale. The owner of the company was willing to do
so but needed a shell for measurements and I supplied one on loan for it. 

The parts are available on Shapeways and on the company's own website in
both scales. The detail is quite nice and makes adding that prototypical
detail much easier. I'm not sure if this company or product had been
mentioned before, but I thought it was worth sharing since N&W bought 99
examples of the RS-11 which lasted through most of their diesel era and
roamed most of the system.

Happy modeling to all!
