The Colorado Central Railroad was a U.S. railroad company that operated in Colorado and southeastern Wyoming in the late 19th century. It was founded in the Colorado Territory in the wake of the Colorado Gold Rush to ship gold from the mountains. It expanded from its Golden–Denver line to form a crucial link connecting Colorado with the transcontinental railroad and the national rail network. The history of the railroad throughout the 1870s was driven at times by a fierce struggle between local interests, led by W.A.H. Loveland, and outside investors of the Union Pacific Railroad led at times by Jay Gould. The early struggle of the company to build its lines was a major part of the early competition between Denver and Golden for supremacy as the principal metropolis of Colorado.
The Denver, South Park, and Pacific Railroad was a historic 3 ft 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." Founded in 1872 by Colorado Governor John Evans, the company was purchased by the Union Pacific Railway in 1880, though it continued to be operated independently. The line went bankrupt in 1889 and was reorganized under a new corporate name as the Denver, Leadville and Gunnison Railway. When the Union Pacific went bankrupt in 1893, the DL&G lines went into receivership and were eventually sold to the Colorado and Southern Railway. In the first half of the 20th century, nearly all the company's original lines were dismantled or converted into 4 ft 8+1⁄2 instandard gauge. The last train to run the old DSP&P tracks was from Como, Colorado on April 11, 1937. A section of the standard gauge line between Leadville and Climax is still operated as a passenger excursion railroad called the Leadville, Colorado and Southern Railroad. At its peak the Denver, South Park and Pacific Railroad had 335 miles (539 km) of narrow gauge line, making it the largest narrow gauge railroad in the state of Colorado.
The Denver Tramway, operating in Denver, Colorado, was a streetcar system incorporated in 1886. The tramway was unusual for a number of reasons: the term "tramway" is generally not used in the United States, and it is not known why the company was named as such. The track was 3 ft 6 in narrow gauge, an unusual gauge in the United States, but in general use by railways in Japan, southern Africa, New Zealand, and Queensland, Australia.
The Colorado Springs and Cripple Creek District Railway was a 4 ft 8+1⁄2 instandard gauge railroad operating in the U.S. state of Colorado around the turn of the 20th century.
There are more than 1,500 properties and historic districts in Colorado listed on the National Register of Historic Places. They are distributed over 63 of Colorado's 64 counties; only the City and County of Broomfield has none.
David Halliday Moffat was an American financier and industrialist.
The Midland Terminal Railway was a short line terminal railroad running from the Colorado Midland Railway near Divide to Cripple Creek, Colorado. The railroad made its last run in February 1949.
The Denver Trolley, formerly known as the Platte Valley Trolley, is a heritage streetcar line in Denver, Colorado, operated by the Denver Tramway Heritage Society. It began service on July 4, 1989.
The Colorado and Southern Railway was an American Class I railroad in the western United States that operated independently from 1898 to 1908, then as part of the Chicago, Burlington and Quincy Railroad until it was absorbed into the Burlington Northern Railroad in 1981.
Standard gauge was favored for railway construction in the United States, although a fairly large narrow-gauge system developed in the Rocky Mountains of Colorado and Utah. Isolated narrow-gauge lines were built in many areas to minimize construction costs for industrial transport or resort access, and some of these lines offered common carrier service. Outside Colorado, these isolated lines evolved into regional narrow-gauge systems in Maine, New York, Pennsylvania, Ohio, Iowa, Hawaii, and Alaska.
The Cripple Creek & Victor Narrow Gauge Railroad is a 2 ft narrow-gauge heritage railroad that operates seasonal tourist trains between Cripple Creek and the city's outskirts to the south. The railroad uses a revitalized section of the original Midland Terminal Railway and the Florence and Cripple Creek Railroad. The railroad's one station and around half of its route is located within the Cripple Creek Historic District, a National Historic Landmark.
The Florence and Cripple Creek Railroad (F&CC) was a 3 ft narrow-gauge railroad running northward from junctions with the Denver & Rio Grande Railroad at the mill towns of Florence and later moved to Cañon City, Colorado, on the banks of the Arkansas River, up steep and narrow Phantom Canyon to the Cripple Creek Mining District, west of Pikes Peak. It was founded in 1893 and went out of business in 1915
Englemann Canyon is a valley along Ruxton Creek, in Manitou Springs, El Paso County, Colorado. It is one of three canyons in Manitou Springs, the others are Ute Pass and Williams Canyon.
The Colorado Springs and Interurban Railway was an electric trolley system in the Colorado Springs, Colorado that operated from 1902 to 1932. The company was formed when Winfield Scott Stratton purchased Colorado Springs Rapid Transit Railway in 1901 and consolidated it in 1902 with the Colorado Springs & Suburban Railway Company. It operated in Colorado Springs, its suburbs, and Manitou Springs. One of the street cars from Stratton's first order is listed on the Colorado State Register of Historic Properties.
The Denver and Intermountain Railroad was an interurban railway that operated 18 miles (29 km) between Denver and Golden, Colorado. Originating as a steam railroad, the Denver, Lakewood and Golden, the line was opened in 1891 and had built an electrified spur leading into downtown by 1893. The company went into receivership and was acquired by the Denver & Inter-Mountain Railway in 1904, changing to simply the Intermountain in 1907 before finally settling on Denver & Intermountain Railroad (D&IM) in 1910. The line was fully electrified at 11,000 volts alternating current in 1909, allowing direct trains to run on city streets to downtown Denver's Interurban Loop. The company was acquired by Denver Tramway the following year, becoming Route 84 in the system. Service ended in 1950 – electrical infrastructure was maintained until 1953 and ownership of the line passed to Associated Railroads, maintained the line for freight as far as Denver Federal Center. The right of way was acquired by Regional Transportation District in the 1990s and rehabilitated to form part of the W Line light rail.
