Foam on Section Three
I'm going to start the foam scenery on Section 3, the Tybee Island section. This appears to be the easiest. There is a 2" slab and 1" slab (3") that covers the base and a 2" and 1" slab (to 6") that make up the Maritinez turntable. There is a 2% grade along the length of the section for the mainline, and spurs are level.

I went through all of the elevations and made some changes. First of all I had calculated all of the elevations from the top of a 2" foam base. This makes assembly calculations difficult, so I recalculated them all to measure from the top of the wood section. Next, I re-adjusted all of the elevations so that the joints were on easy numbers so that I can cut wood support blocks for the track.
Since I keep referring to the sections, I've put in the section numbers as well.
Tonight I'm going down to the basement to finish off Section 3 and then maybe cut the foam. With the exception of the turntable, the rest of this section is very easy. The turntable maybe the last track section I install.
Here is the modified drawing that I'll be working with for Section 3.
