Ted;
Back in the 1970's, maybe late 1960's, Model Railroader Magazine had a N scale project railroad, (thats where they build the RR, step by step, and show how to do it), called the East Glasstop. It was built into a coffee table.
If you are interested, simply go to Trains.com and do a search in their magazine index. Search using East Glasstop. You may be able to order copies of the articles and/or the complete magazines from them.
