dummy locomotive upgrades

[Anonymous]

I usually find the Athearn metal frame is enough ballast, though I wi***hey'd fit metal wheels - I have one GP50 dummy that wobbles somewhat noticably!

You can probably change the wheels by pulling the plastic wheels off of their axles and inserting replacement 42" locomotive wheels made to fit an Athearn diesel, acquired from Athearn or other source. I would add just enough weight to keep the model from derailing on curves. Too much weight is like trying to pull five or six more freight cars.

I have some Athern non-powered (dummy) diesels that I want to replace the palstic wheels with metal and add weight. Can anyone suggest how much weight should be added and what metal wheels might be an easy change to?
