Hi Jacobpaul81,
Here's an attempt at the outer mainline on the benchwork that you designed. It's done in SCARM, which is freeware. Gargraves and Ross were used. Flex for the straights and some curves that needed different arcs and sectionals were to used to easily identify the curves. Those will be flex in the final.
there's spacing issues to decide. I left 12" on the West wall for flats and scenery along the wall and 6" along the NW wall. It's 2"-3" to the edge of the table. Losing the wall spacing would open up the center if you needed it for track.
various size curves were used. The return loops are 106 and the smallest inside in the NE around the water main is 080. I had to use some custom arcs to fit the table in the East coming to the center to follow that angle. So, playing with that angle of the table can make the track work a little easier with 30°, 15°, and 7.5° increments. I had to use a 9° in two places.
I hope this helps you with your design decisions.
