History The Georgetown Loop Railroad was one of Colorado's first visitor attractions. This spectacular stretch of narrow gauge railroad, built by the Georgetown, Breckenridge and Leadville Railway, was completed in 1884 and considered an engineering marvel for its time. The thriving mining towns of Georgetown and Silver Plume lie apart in the steep, narrow canyon of Clear Creek in the Rocky Mountains west of Denver. Engineers designed a corkscrew route that traveled nearly twice that distance to connect them, slowly gaining more than in elevation. The route included horseshoe curves, grades of up to 4%, and four bridges across Clear Creek, including the massive Devil's Gate High Bridge. The Georgetown, Breckenridge, and Leadville Railroad had been formed in 1881 under the Union Pacific Railroad. The Loop portion of the line was the crowning segment of the line, crossing the top of the gorge on a high trestle. Originally part of the larger line of the Colorado Central Railroad constructed in the 1870s and 1880s, in the wake of the Colorado Gold Rush, this line was also used extensively during the silver boom of the 1880s to haul silver ore from the mines at Silver Plume. In 1893, the Colorado and Southern Railway took over the line and operated it for passengers and freight until 1938. Between 1906 and 1918, the Georgetown Loop connected with the Argentine Central Railway in Silver Plume, by which tourists could continue onward to the summit of Mount McClellan. Prior to 1916, the Argentine Central also served several large silver mines on the east side of Argentine Pass. The line was dismantled in 1939, but was
