    You need ideally to superelevate and use easments. Easments are made by moving the radius point in two inches and draw the arc and them freehand draw the ends out to meet the track in a sweeping motion. There are also plastic templates you can purchase and I think you can download a pdf of them from the NMRA website and print some. I do it the freehand method myself. Superelevation is banking and is optional, but the train looks cool going through it. I bank HO curves the thickness of a cerial box cardboard (1/64"?) by using it as shims on the outside of sweeping curves. On an S curve it's import. to have at least ONE car lenght of straight between the curves. If you don't you will have derailments, uncouples, and grow to hate it. Fred
