The Joes were powered by 1,200v D.C. in the case of the South Shore units, and 1,500v D.C. for the Milwaukee Road locos. Since these units used D.C. power transmitted over the catenary, they were internally uncomplicated since the power production and modulation was done by the line side electrical substations. On board the loco it was mostly a matter of stepping down the voltage to 600v D.C. for the traction motors and providing control of the motors. The main carbody contained two sets of large traction motor blowers, air compressors and the transformer and control apparatus. The nose compartments are nearly empty - with only air brake reservoirs and hand brake equipment.

Note that these units were built with spoked wheels.
The main running gear consists of the large steel casting for the main 4-axle trucks and pilot, which was half the length of the locomotive. This casting took all of the train buffer stress, and the two truck assemblies were joined back-to-back in the center with a large coupling pin to transfer the buffering forces and keep the trucks aligned.

The unpowered 2-axle lead and trailing trucks attached to the large main casting under the pilot, and swiveled independently of the main truck frame. A linkage arm between the lead/trailing truck and the main frame prevented over-rotation and yawing motion of the truck.
