My G scale railroad is mainly circus oriented with some logging. I have 3 different layouts. Two layouts are in my train room. One is located overhead with 2 circus trains and one work train and has parallel tracks. The second layout is a 9 X 12 foot table with contains many buildings, lighthouse, coal dumping bins, and also a waterfront. This layout also leads to the outside tracks which are elevated at about three and one-half feet and has a yard and town. The overhead tracks consist of about 90 feet, the table layout has approx. 50 feet and the outside track is 120 feet plus three sidings. Layouts can be seen at the Shasta Garden Railroad Society website and Humbughelangon.com.
