My 'new'  1992 vintage SD-40 locos with Pullmore motors growl pretty good!  BUT....It's not a negative really. I bought them not knowing anything about them....other than they looked good and had an excellent price.  As I ran them the first time.....the motors almost made a good EMD prime mover sound!! They kinda growl like a worked hard power plant! It's a sound system that sould hold up well anyway!!!

Those early 2333's, 2344's, 2353's had such a growl, I call it the "Postwar sound system".

The older, early horizontal motors were the best "growlers"

David make the correct observation here in that it's not so much the PullMor motors themselves that produces the nicest 'growl' but it is the horizontal gearing with a spur running in concert that creates the sound. When the vertical PullMors appeared, they were relatively silent compared to their earlier horizontally mounted bretheren!

I agree! It seems they actually "rev up" as they get moving as opposed to just jack rabbit starting, and the associated sound, does indeed sound like a real diesel.

No artificial laboring here!

 

Oh....BTW, just bought a Post War 1950's 2343 AA set from ebay!

SOMEBODY STOP ME!
