Help with layout design?

Dear Kevin.
I'm sure we are all looking, but no ideas so far. There seems lots of potential here. could you use a removable section where the one opening is for a continuous operation?

That might have to happen to make a continuous loop. Id like to avoid it, and maybe look at some possibilities for point to point to avoid that. I want to get some other non train related stuff down there, and would like to keep that area open, but that might be next to impossible.

Im fine waiting for replys, Just figured Id toss in the new measuerments to help. Thanks.
