Sprung trucks for Lionel 3-Bay Die-Cast Coal Hopper 6-27159

Hello Randy. I’ve been replacing the “improved” (plastic, non-sprung) trucks on my Friendship Train PS-1 boxcars with trucks from donor cars. Don’t hold me to this, but I believe the trucks on your die-cast hooper cars are the same as used on many other scale cars of a similar vintage. You might be able to find inexpensive (non-diecast) donor cars at train shows and pay less than what replacement trucks would cost (if available). But, one thing I would definitely not recommend is trying to retrofit them with “new” trucks from the parts department. They will be the plastic, non-sprung versions (and more expensive than a donor car).
