[quote user="Curmudgeon"] If it's Lionel 3-rail, it was plated.This is literally powder.The rail hads are gone in places, webs gone, base gone, I do have a later shot, I'll have to upload it.One thing about painbt:The engineering of how railroad wheels work is there in no differential.The right wheel is locked to the left wheel on any given axle.In the prototype, the angle of the tread and the fillet at the flange caused the wheels to move across the rail head, finding the "sweet spot" where the diameter of each wheel matched the speed differential of the individual wheels on a curve.Curvature is therefore limited.Using R-1 (Bachmann curves) is the absolutely worst case scenario for this, as every wheel on every axle will be fighting the opposing wheel and something will be slipping.This "wheel slip" created friction, which rubs at the finish/paint of the rails.I could post photos of my locomotive wheels where the plating is gone, as is the copper undercoat, and I use 6'8" radius, not 2' radius.[/quote] Wow!!! I have never seen metal rust completely away in less that 3-5 years! What do they use in that Bachmann track that accelerates the oxidation process?I have an old Minneapolis Moline tractor that has been sitting out in the meadow in font of my house for 40+ years exposed to the elements. There is not one spot on that old girl that has rusted through. The yellow paint has long gone, but the metal, while covered with rust, is still sound.Junnie
