Yes I picked up metal wheels at my LHS. They're easy to replace. It greatly reduces the possibility of stalling at insulated frogs. Pulling power is reduced but will still do pretty well.
You can also get the metal wheels from Walthers free.

Rio Grande vs. Santa Fe.....the battle is over but the glory remains!
Same here. I ordered through my LHS. Walther's would not offer me free ones when I was emailing with them about the issue.
Mine came in a small plastic zip lock bag. Label on it from LHS says:
THA Trains:HO Gauge A P2KGeared Drivers (2)
I paid like $2.99.
Good luck,
Tom
