First I'll start off by stating that I am not a fan of the Aristo-Craft 3 axle motor trucks. A crappy rail power pickup design along with no spare parts available.

I do like the USA T design as they use both the wheels via axle bushings and slider skates to pick rail power. I'm also a big fan of using traction tires. My idea is keep the locomotive weight light and pull good using traction t
