Denver Union Station was built to gather the railroads

History and culture Denver County Denver railroad history

The name “Union Station” is a clue to its purpose. In the railroad era, many separate companies ran lines into a city. Rather than scatter their depots, they pooled into one shared, or “union,” station.

Denver’s Union Station opened in the early 1880s near the South Platte. At the height of the railroad age, a great many trains a day moved through Denver, and the depot was the front door to the city. After an 1894 fire, the central building was rebuilt, and the central section many people picture today dates to 1914. Over the decades, passenger rail faded, and the building grew quiet.

A long restoration brought it back. The station reopened in 2014 and now ties together intercity trains, the airport rail line, buses, and light rail, with shops and a hotel inside the old hall.

Why care: Union Station explains why this corner of downtown grew the way it did, and it is still a practical transit hub. For its documented history, see History Colorado.
