Union Station remains a very visible and vital component of the city’s transportation past present and future, uniting DART (Dallas Area Rapid Transit) bus and rail system, Trinity Railway Express and AMTRAK in a building that is registered as a National Historic Landmark (NHL), a State Archaeological Landmark (SAL) protected under the Antiquities Code of Texas and a City of Dallas Historic Landmark. There are few historic buildings in Downtown Dallas that have retained their original architectural integrity.

Union Station is an 110,000-square-foot public-use complex with 56,000 square feet of leasable area, which includes 10,000 square feet to support transportation services, 13,000 for office space and 33,000 for meeting, catering and hospitality uses.
