Trackplan - Lower Level

I'm finally honing in on the trackplan, although I'm sure things will continue to change as I get further along. Here's the lower level, showing the yard and wye at Chattahoochee. This is the central point of the route, where the L&N and Seaboard meet. It's also the northern terminus of the Apalachicola Northern Railroad, although I haven't included any trackage specifically for the AN at this point. Also I may consider adding some additional storage/staging trackage on this level if it will fit.
