Some HGV's have rubber springs, these are fitted in a sort of V formation and are in compression and torsion. Often found on cement mixer trucks and bin lorries. I think may have been used on rail vehicles. These would be simple to make and give better performance ? Can't remember any details but should be on google.

The shock absorbers or to give them their correct name dampers in a lot of cases have bump stops fitted to the damper shaft which in effect are a progressive spring which are designed to increase the spring rate for a small movement (travel) of the suspension. Although some are rubber most or at least the better ones are a foam polyurethane. May be some stock polyurethane could be machined into a conical shape to give a progressive spring rate to allow for differing weights, may well work for passenger carriages as well.
