Burlington,
You'll find that layout photo features whether in OGR or CTT rarely include piece by piece listings of track sections used, which is not appropriate to some layouts anyway as Rich mentioned.
The emphasis in a layout feature is to showcase in photos and text the results of another modeler's efforts, that is, how they have created a complete, scenicked, operating layout. The intent is not necessarily to provide detailed instructions as to how a trackplan could be duplicated.
The layout planning articles in CTT that I believe you are referring to are a different category of article. In those, tracks plans with complete inventories of track sections needed are included. However, usually the layout has never actually been constructed. The graphics show suggested scenery elements, but not completed layout photos since there are none.
However, anyone wishing further information from the author of an OGR article may contact the OGR office and make a request that the author contact him or her to provide more information. The request will be forwarded to the author who in most cases will be happy to contact them.
Several readers of my articles have done this in the past, and we now correspond regularly in some cases. Most authors appreciate the fact that a reader will take such an interest in an article.
