Denver, Leadville and Gunnison Railway

The Denver, South Park, and Pacific Railroad (later called the Denver, Leadville and Gunnison Railway) was a historic 3 ft (914 mm) narrow gauge railroad that operated in Colorado in the western United States in the late 19th century. The railroad opened up the first rail routes to a large section of the central Colorado mining district in the decades of the mineral boom. The railroad took its name from the fact that its main line from Denver ascended the Platte Canyon and traversed South Park, hence its popular name "The South Park Line." Despite its lofty goals, the line never connected itself with the Pacific or any transcontinental line, apart from its terminal at Denver Union Station.
