The left portion of the layout will be two levels with the staging tracks being on the lower level. The track to the lower level will need to descend to the staging tracks. The tracks to the upper level will need to climb. You have 10 feet to get the necessary clearance between levels. Eight inches between level tops (remember that there will be supporting structure, etc.) will give you a 3.3% grade. If you can start either grade sooner will be better.
The layout will have three different table heights. Two, highest and lower, on the left and middle level on the far, far right.
If you post your SCARM files you'll likely get more suggestions and help.
