Here You see the Original Drawing from Dec. 1967 Model Railroader. This is shown with the original 4'x8' grid markings. Most of the recent scenic work with profile boards and plaster cloth has been at the lower part of the plan where the lower track curves under the upper and dives into a tunnel. This is also where the 3 section truss bridge will be placed.
Sorry about how long to post a track diagram. I just figured how to import images from email today, I guess you can teach an old dog new tricks. More later.
