@gunrunnerjohn posted:Simple solution? I think not! Imagine how expensive it would be to develop independent suspension for the weights that railcars carry! There's surely a very good reason this has never been done, and I suspect it's a question of economics! The present system of tapered wheels with fixed axles works very well. The tapered wheels also actually help to gently steer the car around the curves as centrifugal force pushes it to the outside of the curve.
Don't fix stuff that ain't broke!
I think Alan meant the fast angle wheel is a simple-to-manufacture solution in lieu of independent rotation wheels, which he acknowledged are more costly and not used at this point for our O gauge trains.
