I would like to get the groups input on a plan that is based on Iain Rice's Roque Bluff.

This would be built in O Scale, 2 rail, Proto 48 and constructed in a 20' room along one wall. Sections would be designed for relocation of home, not portability to shows.  The depth is 24" at the ends bowing out to 36" in the center. Trains would enter from the right from cassette or other type of staging. Train length would be one Loco and maybe 4 or 5 cars with caboose.  Car lengths would be 40' type box cars. The run around leed on the left will hold one GP9 loco and one car up to 60' in length.

Modification from the original plan was the elimination of a switch back style siding to a facing point siding at the rear left of the layout to reduce depth. Boat house was scaled back, and flipped to the left,  the pier was rearranged to hide the section joint. The center siding between the runaround tracks could be changed to a team track if the small buildings won't fit.

My main concern is the depth but without eliminating a lot of scenery, which kills the effect, I don't see a way around it. I have given thought to tilt down sections for track laying but once the track is in place I don't see that great a need for it. Given the simple plan the sections could be removed to lay the track and replaced for scenery.  All track is within 24" of the front edge. 

I have this draw up in a cad program and used a paint program to edit the original photo plan.

Thank you for the help.
