Historic railroad that operated in the western United States during the late 19th century.

Formed in 1867 in the Colorado Territory, the company operated lines in Colorado and present-day southeastern Wyoming in the 1870s until merging with the Kansas Pacific and Union Pacific railroads in 1880.

The railroad was formed primarily to create a link between Denver and the transcontinental railroad at Cheyenne, an achievement that was widely credited at the time with making Denver the dominant metropolis of the region.
