Model Railroad Design

Click to enlargeIf you are about to build or design a layout, you will find yourself facing a number of decisions. You need to decide on the primary goals for your layout, design the layout, and refine the plan. The buildings and landscape are integral to a great track plan, and you may even want to scratchbuild a building or two to really personalize the layout.
