Tucson is an Amtrak train depot in Tucson, Arizona, served three times a week by the Sunset Limited and Texas Eagle trains.
The depot was built in 1907 by the Southern Pacific Railroad (SP). It was designed by the SP's architect, Daniel J. Patterson, who designed a number of depots during the same era, including the San Antonio Station.
In 1998, the City purchased the entire depot property from the Union Pacific Railroad, which had absorbed the SP. Restoration of the main depot building and the three adjacent buildings, to their 1941 modernized Spanish Colonial Revival architectural style, was completed in 2004. Spanish Colonial Revival elements include the stuccoed brick walls, red clay roof tiles, and colorful, decorative tilework in the waiting room. The station and other railroad buildings are included as contributing resources to the National Register-listed Tucson Warehouse Historic District.
The Old Pueblo Trolley and Sun Link extended their historic streetcar lines to the depot in 2009.
