The Colorado and Southern narrow gauge was slowly abandoned piece by piece in the 33 years between 1910 and 1943. The first line to close was part of the Gunnison Line between Hancock and Quartz. This included Alpine Tunnel, although rail was not removed until the 1940s. The isolated segments between Quartz and Gunnison and Gunnison to Baldwin were leased and later sold to the
Denver and Rio Grande Western Railroad. Quartz to Gunnison survived until 1936 and the Baldwin Branch lasted until 1954. The next line to be ripped up was between Garos and
Buena Vista. This left another isolated line between Buena Vista and Hancock, which was abandoned four years later. The Morrison Branch was removed in 1926. In 1931 the portion of the Blackhawk branch between
Central City and
Blackhawk was removed. Times were tough during the
Great Depression and by the end the narrow gauge was worn out. What was left of the former Denver South Park & Pacific between Denver and Leadville including the Alma and Keystone branches was removed in the summer of 1938, excluding the 20-mile portion between Denver and
Waterton and the 14-mile segment between Leadville and
Climax. The next line to fall was between Silver Plume and
Idaho Springs, in 1939. This included the famous
Georgetown Loop. In May 1941 the last of the Clear Creek lines began being torn up between
Golden, Colorado and Idaho Springs. This included the Blackhawk branch. The
dual-gauge third rail that had allowed narrow-gauge trains to run between Denver and Golden was also removed. (However, the
standard gauge segment still exists today to serve the
Coors Brewery.) Most of the track was removed in 1942 between Waterton and
Chatfield. The rest was converted to standard gauge, ending all narrow-gauge service out of Denver. The last narrow-gauge operation, between Leadville and the Climax mines, was converted to standard gauge to handle heavy traffic from
World War II. The last Colorado and Southern narrow-gauge train, pulled by engine 76, ran the 28 mile roundtrip on August 25, 1943. The next day standard-gauge locomotives began hauling the loads. The C&S narrow gauge thus became part of history. ==Narrow gauge today==
