Draw a layout plan for a garden railroad in 1:20.3 scale running on G Scale Track. The garden railroad will fill a 20ft by 20ft space. All track radii will be at least 7 ft. This narrow gauge railroad is a lumber railroad and will have the following elements. 1) a mountain in one corner of the space, 2) a creek running from one corner to the opposite corner, 3) the main continuous loop will contain a tunnel and a trestle over the creek in the mountain area, 4) a lumber mill with a railroad siding - the siding connected to the main line, 5) an engine servicing area connected to the main line, 6) a separate railroad spur to a logging area on the mountain.
