After discussions with the editor at OGR magazine, I should not publish a labeled track diagram or a list of track sections needed for layouts that might appear in the magazine. Subscribers want original work in the magazine, not a re-publication of layout plans published openly and freely on the forum. Sorry to disappoint, but I understand the reasoning.
I am working on a concept that builds this layout from a single 4x8 sheet, to the "L" pictured above, and then to a "U" shape not previously shown, in three stages. I have the layout designed, now I have to create the illustrations in three phases, and write the article.
The article will be longer than I usually do for the magazine. If it is not suitable for publication, I will post all materials here on the forum. Best I can do for now.
