Being an a 3RS (+/-) and not a 2RS, I'm grossly under-qualified to appraise the situation but that won't stop me from asking a stupid question:  What prevents you from powering the rear truck in the same manner, after replacing the single shaft motor with a double, and stuffing the electronics & speaker under the motor and inside the fuel tank?  More weights could be added on the rear to mirror those on the front, under the drive shaft, and you have sound/control, weight and 8 wheel drive.  I know that you're an artist and a collector, not a throttle puller, but still I cannot imagine you settling for second best.

Ditch those cute little lead weights and add a couple tungsten copper alloy cylinders in place.  Pull will increase dramatically.  Tungsten -copper is 1.5 times denser (heavier) than lead.  You can get virtually any size you need from Mi-Tech Metals:

Oh, and nice job by the way. 

 

 

 

 

Nifty locomotive!   Housekeeping detail:   Burlington's Baldwins were concentrated (per locomotive assignment sheet from 03-01-55) on the Chicago Division (13 units), particularly switching Clyde Yard, and North Kansas City, MO (17 units).  Most - if not all - of Burlington's steam power came from Baldwin, so not surprising the Q threw some early diesel business to Baldwin.
