Steel wheels shorting out DCC system - Model Railroader Magazine

Guys, the original poster's problem and question has been answered long ago and several times.

He has _metal_ trucks on the car.

He is using metal wheels with metal axles. One of the wheels will be insulated from the axle.

He must make sure the insulated wheel is on the same side for every axle he installs or it _will_ cause a short through the metal _truck_.

If all the insulated wheels are one side, no problem.

It's not a production problem with uninsulated wheels, it doesn't matter if the wheels are nickel-silver, brass, steel, copper, gold, whatever. It also has nothing to do with the DCC system. A short is a short.

Everything else just detracts from the original question.
