Thanks to all! All of you must have known the math in order to accomplish something on your layouts. Now I know the math also, but what I am concerned with is the transition from the flat surface to the grade at the bottom and also the transition from the grade to the flat surface at the top so as to hopefully have all the drive wheels on the locomotive keeping in contact with the track at the bottom and the top of the grade.
