Mark, I'll be glad to help get things connected. I've always been concerned about your being able to get to the access hatches. Anyway, here's attempt #1. Note the elevation is only 5" because of the passing siding. If you don't intend to park cars there, you could put the whole section on the grade, but since you are no longer crossing over any lower tracks, I'm not sure it's worth it to get a higher elevation.
