Alpine tunnel telegraph station
The 'Denver, South Park, and Pacific Railroad' was a historic
narrow gauge railway 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. The company operated as an independent railroad from its founding in
1872 until it was sold in foreclosure proceedings in
1889. Its lines later became part of the
Colorado and Southern Railroad. In the first half of the
20th century, nearly all the company's original lines were dismantled or converted into standard gauge. A section of the standard gauge line between
Leadville and
Climax is operated as a passenger excursion railroad called the
Leadville, Colorado and Southern Railroad.
Description of lines
The company's main line was 3-foot gauge and went from
Union Station in Denver up the valley of the
South Platte River to the town of
South Platte, then followed the North Fork of the South Platte through
Buffalo Creek and
Bailey. West of Bailey the route along North Fork and through the north end of the
Tarryall Mountains essentially followed the route of present-day
U.S. Highway 285 to
Como, where it branched northward (see below). From Como the main line transvered South Park to
Garo, where a spur went northward to
Fairplay and
Alma. The main line continued south over
Trout Creek Pass. On the western side of the pass, a small spur of the main connected to
Buena Vista, then traversed the southern end of the
Sawatch Range through the
Alpine Tunnel to
Pitkin and
Gunnison. The distance along the main line from Denver to Gunnison was approximately 208 miles.
A principal branch of the main line north from Como went over
Boreas Pass to
Breckenridge,
Dillon,
Keystone,
Frisco and Climax. This branch terminated at Leadville.
A small 7 miles branch of the main line 9 miles south of Denver connected to
Morrison (this line was actually constructed first).
History
The company was incorporated in the
Colorado Territory as the "Denver, South Park and Pacific Railway" on
October 1,
1872 with 2.5 million dollars in capital. Less than a year later, on
June 14,
1873, it was reorganized as the "Denver, South Park and Pacific Railroad" with an increased capitalization of 3.5 million dollars. In August of that year in began grading the line from Denver to Morrison. The first rails were laid on
May 18,
1874. On
June 20, the tracks reached Morrison, and on
July 3, scheduled service began between Denver and Morrison with two 2 round-trip mixed trains per day.
From 1874 until 1878, the company progressed slowly on its main line, using a series of different construction companies as it struggled to remain solvent. The tracks finally reached the mouth of the Platte Canyon on
May 4,
1878, 20 miles from Denver, and by
June 2, the tracks reached 12 miles up the canyon. The tracks reached Buffalo Creek on
June 17. The following year, on
May 19,
1879, the tracks reached to the summit of
Kenosha Pass and on
June 27 they reached Como.

Approach to the Alpine tunnel
In November 1879, with the tracks only as far as South Park, the company contracted for the initial construction of the Alpine Tunnel, with an expected finish date of
July 1,
1880. The following month, the tracks reached to the summit of Trout Creek Pass. That same year work began on the branch line ("High Line") to Leadville, and on
July 2, 1880, the first train arrived in Leadville.
The Alpine Tunnel was "holed through" on
July 26,
1881. The main line reached Gunnison the following year in
1882.
The railroad went into receivership on in May
1888. On
July 17,
1889, the company was sold at foreclosure proceedings to the
Denver, Leadville and Gunnison Railway, a new railroad which was formed to operate the DSP&P lines. The successor company went into receivership on
August 4,
1894. The Colorado and Southern, charted in
1898, took over the former DSP&P lines in January
1899. The Colorado and Southern started dismantling in
1910 with the closure of the Alpine Tunnel. In
1930, the C&S attempted to shut down the main line through the Platte Canyon, in cooperation with the Denver Board of Water Commissioners, who desired to build a dam in the canyon (the dam was never built). Nevertheless, the construction of modern roads in the Rockies led to a decrease in revenue and traffic. The last freight and passenger trains between Denver and Leadville operated in April
1937, and on
April 10, 1937, the South Park Line officially closed down. The last regular freight train operated between Denver and Como on
April 25. The last narrow gauge section, between Leadville and Climax, was converted to standard gauge on
August 25,
1943.
