Union Station is a Washington Metro station in Washington, D.C., on the Red Line. It has a single underground island platform.
The station is located in the Northeast quadrant of the city under the western end of Union Station, the main train station for Washington, where connections can be made to Amtrak intercity trains, as well as Virginia Railway Express and MARC commuter rail trains to suburbs in Virginia, Maryland, and West Virginia.
The station was originally named "Union Station–Visitor Center" but when the National Visitor Center there failed, it was renamed Union Station. One or two pylons still read "Union Station-Visitor Center", and a number of older stations still display this name on signage.
