Denver Union Station is the main railway station and central transportation hub in Denver, Colorado. It is located at 17th and Wynkoop Streets in the present-day LoDo district and includes the historic station house, a modern open-air train shed, a 22-gate underground bus station, and light rail station. A station was first opened on the site on June 1, 1881, but burned down in 1894. The current structure was erected in two stages, with an enlarged central portion completed in 1914.
