Depicting a double-track mainline crossing a narrow river valley on variety of bridges, this layout has connecting tracks and cross-overs that allow trains to easily flow from one mainline to the other. Schematically, this layout is two over-and-under figure 8's, interconnected at a variety of points. Two trains can run continuously on the mainline and another can be switching cars in the yard. In addition, the track plan lends itself to some spectacular scenic effects, especially in mountain and tunnel construction. TABLE SIZE: 11' x 28.5'
