Is there a 'rule-of-thumb' about how to design the inclination of track to produce prototypical superelevation? I have read that for HO, one should start with a 0.010" elevation of the outer rail at the beginning of a curve, then increase that to 0.020" after about a 12" distance, then after another 12" distance increase to 0.030" for the center section of the curve and then decrease back to 0" in a manner symmetric with the design used for the increase. But shouldn't the design depend on the curve radius?
