But are you a 3-Rail modeler, or a 2-Rail modeler? In 3-Rail there isn't much current draw through the wheels, as there is in 2-Rail. In 2-Rail even the plastic wheel sets are exposed to the DC voltage in the two rails and the corresponding oxidation deposits are picked up on the non-metal wheels (just like in HO modeling).
