Alternately, just ease the gradient where the track diverges so you don't get the drastic change in height within the bounds of both track sections.
I ripped out the track, and lowered the grade a bit, both up and down. I figured a proper length for a transition as being <>120 feet, half again the length of the coaches. I laid the switchback and turnout dead level (correct for the prototype) and extended each leg out about 60 feet.Then taking 120 feet at a jump, lowered the downhill leg .25% at a time until I had the correct downgrade. I did the same with the uphill leg and it seems to be working fine now. Using the grading tool to fill back. I don't know, but you may be able to use shorter chunks.
