Hi Ian, I remember an article from many years ago about curves in the smaller scales. The first involves leading a train into a bend on a shallow curve before going into the full curve. It would be something like having a bend of Aristo 8' with the first curved section being 12'. The second is 'super elevation' where the outer edge is higher - as you have done. For our scale I think it would be better to construct the track base out of concrete and actually screw the track down to it. So, coming along the straight the train would go into a large radius curve with the elevation of the outer track actually starting about 2 or 3 inches BEFORE the curve and rising along the curve coming to full elevation before the main smaller radius curve is met. A similar exercise would be needed coming out of the curve. I think it would be important to start the elevation on the straight section because the wheel is entering the twist in the track in a straight line rather than having to negotiate a curve at the same time. Makes sense to me - sort of! Cheers, Kim [tup]
