Because of the equalization in the truck suspension was then screwed up, less weight was transferred to the good wheel. It would have had a flat spot in the tread but nowhere as severe.



Random:

If you guys like trains and ever find yourself in Old Sacramento, then you would dig the Railroad Museum. They even have one of the original Gold Spikes when east met west.
