I am planning my first O scale layout (I currently am an HO modeler). I want something simple to start, so I was going to build four sections (each of which will be 3' x 6') that can be arranged in pairs lengthwise. A backdrop will run down the middle. I will then put some 180-degree curves at the ends built by Model Railroad Benchwork (https://www.modelrailroadbench....com/modular-pricing) to make essentially a large oval layout. The end curves will fit 0-54 track, which is sufficient for the trains I want to run.
Each side of the layout will have one scene that is essentially 3' deep and 12' long (fitting on 2 sections), and I will be able to walk around the layout and see two separate and distinct scenes. All track will be near the outer edge of the layout to maximize access. I will make each of the benchwork sections separate so that they can be disassembled if I move, and should I want to add more sections or rearrange them I can do so without much loss in effort.
I was going to frame each of the sections with 1x4 lumber, and use cross braces every 16-18" made from 1x3. It will be topped with 1/2" plywood. I don't think I need to use 1x4 lumber for everything, and using the smaller 1/3 stock for the braces will save on weight. I don't need to walk on it or anything.
Any thoughts to my plan? Thanks.
