Built in 1916 and designed in the acclaimed Beaux-Arts Classicism style, Union Terminal consolidated all of the passenger rail stations in Dallas into one terminal. In 2008 the building underwent a $23 million renovation and has been restored to its former glory. Various upper-level rooms are rented out for private parties, meetings and receptions, and there is office space available for commercial lease. It is home to an Amtrak station and a Dallas station for the Trinity Railway Express commuter line, and it serves as a DART light-rail station. Union Station is linked by underground tunnel to Reunion Tower and Hyatt Regency Dallas.

Union Station is owned by the City of Dallas and leased under a master agreement by affiliates of Hunt-Woodbine Realty Corporation.
