Pueblo Union Depot is the historic railroad station in Pueblo, Colorado. It was built in the Richardsonian Romanesque style in 1889-1890 and added to the National Register of Historic Places in 1975.HistoryInitially the station was served by the Denver & Rio Grande Western Railroad, the Atchison, Topeka and Santa Fe Railway, the Colorado & Southern Railway (which was acquired by the Chicago, Burlington and Quincy Railroad in 1908), the Missouri Pacific Railroad, and the Chicago Rock Island & Pacific Railroad. Today the Union Pacific Railroad and the BNSF Railroad share use of the tracks, and the depot is privately owned. Regular passenger train service no longer exists but proposals including the Front Range Commuter Rail, which would provide service to Denver and Colorado Springs has been made. In addition, the depot may soon be included on the route of the Southwest Chief.
