Freight car truck side bearings

A while back, I decided to try making side bearings for my trucks. I used .012" phosphor-bronze wire (wound around a 1/32" wire for a mandrel) to make the spring. They are anchored to the bolster with 1/32" rivets. The bolster is 3d printed SLS nylon. If I could ever get around to finishing a freight car, I could tell you if they work or not.

On a practical side I think they would need to rub on another metalic surface to give some strength to the rubbing. Also perhaps some lubrication and cleaning once a Year depending on the amount of running they would get. It is a dusty dirty environment in the Garden. Would certainly help to stop any rocking that a vehicle might be tempted to do.
