Trains were first introduced to Denver, with the Denver Pacific Railway in 1868, which connected Denver with the main transcontinental line at Cheyenne, Wyoming. Due to the popularity of trains, there were numerous railroads and railroad stations. To accommodate to passenger transfers between the different railroad lines, the Union Pacific Railroad proposed to create one “Union Station”. Thus, in 1880, the owners of the four main railroads, the Union Pacific, the Denver & Rio Grande Western, the Denver, South Park & Pacific and the Colorado Central, agreed to construct Union Station. The station opened to great interest in May 1881.
However, when the train business declined, Union Station experienced many changes. Although Union Station still serves passenger traffic today, Union Station remains first and foremost, as a historical significance.
