Staging to represent the old Upper Level

I can make the staging work according to AutoCad. What I didn't count on was the tortoise machines under the yard at Searsport, which will be above the staging. We could have a problem with the clearance under the yard. Since I don't have Searsport completely figured out, I'm not if I'll be able to work it out.
I originally decided to use a staging yard with a return loop to minimize the handling of trains. Since I have a wye on the mainline I decided that it could be a stub ended staging. I could back the trains out onto the wye between sessions and turn them, just like I did on the old layout.
