Ralph,
Since the maxium grade that one should use is around 4 percent with 2
percent more realistic, bending the subroadbed to that transition is not
difficult. I normally transition from a level to a say, 2 percent grade, over
two or three feet. This is enough that couplers won't dip in the grade change
and have uncoupled trains. Same with the top of the grade.
Hope this helps
