@Tranquil Hollow RR Sorry Jay - I totally agree with Chuck. I think you would be better off taking the benchwork apart and starting over. There are enough planners on this forum who can help pull a track plan together for you. Given your space you will also need to move away from a walk in to get the 072 dia curves. You will never regret having the big curves even if you are not going to run big iron. I also agree with Tom Tee on the lift ups. I got rid of my walk in due to limitations on track layout possibilities along with small space and ended up being able to have 072 curves and 3 lift out bridges to access the center of my layout.
Since its been a year - throw some track down in a couple of loops and run some trains while the plan comes together.
Tranquil Hollow sounds like it needs some verticality so you can have a "hollow" on the layout. Configured as is you are either flat or have to cut holes in the decking. Looks like you already have the foam risers, but you could simply build the sub-road bed to the desired grade.
