Been 10yrs and everything G in boxes - hopefully will build a freight yard with a couple of short lines. Suffering from lack of track and SW鈥檚 馃ゲ. Recently finished rebuilding a UP 20 Tonner, Mighty Moe. Was torn down for year's, collecting dust. Placed on live track today - runs great. Have to unpack a NW2 see how she runs. Most of Motive power is UP with a Norfolk & Western EMD SD70. All buried under like cartons never opened. Arrrgh.

Awesome details on Split axles and how to repair. Certainly an inexpensive assembly from USAT. Axeles should have been pressed fit into a brass gear hub.

BTW - in your list of cleaners, lubes etc. The best label remover and decreases (water soluble ) is a product known as Tidy Pen. Made from pure orange oil. Available from Amazon industrial disty鈥檚. Has a replacable felt nib 馃

Brass hub would have been an issue for 2 reasons: brass worm on brass worm gear.... bad idea. Also the plastic axle/gear insulates the wheels from each other, and with the wheels electrically connected to the half axles allows power transmission throught the axle internal and external to the motor block, much superior to sprung brushes on the back side of the wheel.

Good design, crappy gear casting... been that way forever.

Yeah, even manufacturers have made the mistake of same metal for both gears and torn them up. Of course steel worm and brass worm gear is good, noisy but good.

Good power pickup without brushes is great, since brushes wear, the brush springs collapse under high current (derailment and short), and the brushes get contaminated with grease/oil.

Early on Bachmann did metal "brushes" on the backs of the drive wheels, noisy and chewed up the metal. Aristo and USAT pick up through half axle or end of axle...
