Great Circle Line & Points North Rail Road is a model train layout that uses Digital Command Control (DCC) technology to automatically operate O-Scale trains, while they traverse a tangled maze of three-rail track.

Locomotives and rolling stock — constructed primarily out of lithographed tinplate — mimic designs commonly deployed during the golden age of steam. Buildings, landscaping, and special effects suggest a whimsical and very wintery, arctic environment. A curved backdrop of mountain peaks and night sky, which partially extends around each side, confines the audience’s viewing area to just the front of the layout. Orientation of scenery and visual tricks in perspective favor such a restricted line-of-sight.
