Just bought EK jr engine and some matching cars for the grankids.
Where can I buy parts - trucks, steel wheels, knuckle couplers, etc.
Bachmann sells their wheels separately, but you're on your own for the trucks. Unfortunately, Bachmann hasn't been convinced of the merits of selling a ready supply of parts. Having said that, USA Trains does sell parts, and their archbar trucks are virtual clones of the Bachmann trucks, albeit with different couplers.
You may also have luck calling Bachmann's parts department, as they do sometimes have parts in stock that they strip off of returned merchandise. I would imagine trucks and couplers would be at least somewhat accessible there. They have a 1-800 number, though I don't recall what it is offhand. If you search these forums, you're bound to find it.
Later,

You can also find these parts on eBay frequently.

Thanx for the guidance. I will try both sources.
