I have a 4x8 layout on plywood/foamboard and I have laid out my code 83 track the way I want it. Being new my question is I want totake up the rail and lay down cork roadbed - do I outline (mark) the rail layout on the foam and the added width for the cork? I am hoping there is a way that some of you would be able to give me a good idea to be able to progress with my layout. Thanks in advance.
