I am in the process of designing my second permanent layout (first one was dismantled for the move to a new house). My first layout was 4x9 using RealTrax (O-36 curves) for two main lines and two sidings. Now that I have more space, the new layout will be 16x10 using ScaleTrax. This time, I'd love to have 3 main lines, a yard, and a reverse loop. I've been toying with some ideas and have come to the design iteration that you see in the attached SCARM file and the screenshot. I really wanted to incorporate a reversing loop and dedicated yard since I didn't have space for these on my first layout. The spurs on the left side of the S curve in the middle are purely experimental and are in no way finalized. I've tried to keep the track spacing fairly considerable so that I won't have to worry about interference from larger engines and rolling stock.
Some general info for the attached screenshot: all curves are O-72 and some spans of FlexTrax are used. Also, all of the yard switches are #4s and the ones that aren't yard switches are O-72.
My main concerns are that I have too much going on in the space given and that there will be too much train/track action to leave room for ample scenery. Any thoughts and suggestions regarding any part of my current design would be greatly appreciated as I am new to this forum and typically get stuck inside my head!
