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. Service began on March 27, 1976, with the opening of the Red Line. It is the busiest station in the Metrorail system, averaging 29,197 passengers per weekday as of May 2017.

The National Postal Museum, located opposite Union Station in Washington, D.C., United States, covers large portions of the Postal history of the United States and other countries. It was established through joint agreement between the United States Postal Service and the Smithsonian Institution and opened in 1993.

Owney (ca. 1887 – June 11, 1897), was a terrier mix adopted in the United States as a postal mascot by the Albany, New York, post office about 1888. The Albany mail professionals recommended the dog to their Railway Mail Service colleagues, and he became a nationwide mascot for nine years (1888–1897). He traveled over 140,000 miles throughout the 48 contiguous United States and around the world as a mascot of the Railway Post Office and the United States Postal Service. He was the subject of commemorative activities, including a 2011 U.S. postage stamp.

The Postal Square Building (formerly the City Post Office) served as the main post office for the city of Washington, D.C., from the building's completion in 1914 to 1986. It now houses the National Postal Museum, the Bureau of Labor Statistics, and offices of the United States Senate. Architect Daniel Burnham designed the building in the Beaux-Arts style—the same style Burnham used for the neighboring Union Station. Construction for the Postal Square Building began in 1911 on a lot near the Capitol. Planning began with a 1901 proposal by the Senate Parks Commission. The commission called for three buildings to mark the northern end of the Capitol complex. While the first two buildings in the plan, Union Station and the Postal Square Building, were completed early in the 20th century, the 1901 plan would not be fully implemented until the completion of the Thurgood Marshall Federal Judiciary Building in 1992. A major renovation from 1929 to 1935 expanded the building for increased mail processing and service capacity. By the 1950s, renovations had removed many of the Beaux-Arts features of the building. The main hall and lobby area only showed traces of their former grandiose design with modernist elements replacing the Beaux-Arts style. The building received another major renovation in the early 1990s, during which the original appearance of the lobby and main hall area was restored. The National Postal Museum moved into the building in 1993 following the renovations. The Bureau of Labor Statistics and the Capitol City Brewing Company also moved into the building during the 1990s. (Capitol City Brewing Company closed in 2011 to make room for an expansion of the National Postal Museum.)

Washington Union Station, known locally as Union Station, is a major train station, transportation hub, and leisure destination in Washington, D.C. Designed by Daniel Burnham and opened in 1907, it is Amtrak's headquarters, the railroad's second-busiest station, and North America's 10th-busiest railroad station. The station is the southern terminus of the Northeast Corridor, an electrified rail line extending north through major cities including Baltimore, Philadelphia, New York City, and Boston, and the busiest passenger rail line in the nation. In 2015, it served just under five million passengers.An intermodal facility, Union Station also serves MARC and VRE commuter rail services, the Washington Metro, the DC Streetcar, intercity bus lines, and local Metrobus buses. It carries the IATA airport code of ZWU.At the height of its traffic, during World War II, as many as 200,000 passengers passed through the station in a single day. In 1988, a headhouse wing was added and the original station renovated for use as a shopping mall. As of 2014, Union Station was one of the busiest rail facilities and shopping destinations in the United States, visited by over 40 million people a year. However, the COVID-19 pandemic and other factors caused a sharp decline in retail and dining; by late 2022, more than half its commercial space was vacant, but Amtrak is attempting to regain control of the station and plans a major renovation and expansion.

The National Visitor Center was an ill-fated attempt to repurpose Washington, D.C.'s Union Station as an information center for tourists visiting the United States Capitol and other Washington attractions. It opened for the Bicentennial celebrations in 1976, but it never was able to attract enough crowds to sustain its operating costs, and it closed in 1978.

Columbus Circle, also known as Union Station Plaza or Columbus Plaza, is a traffic circle at the intersection of Delaware, Louisiana and Massachusetts Avenues and E and First Streets, Northeast in Washington, D.C. It is located in front of Union Station right next to the grounds of the United States Capitol. Union Station and its access roads interrupt this circle on one side, forming an arc. The Thurgood Marshall Federal Judiciary Building is located on the eastern side and the National Postal Museum is on the western side of the plaza next to Union Station. Both buildings are on the northern side of Massachusetts Avenue NE.

Columbus Fountain also known as the Columbus Memorial is a public artwork by American sculptor Lorado Taft, located at Union Station in Washington, D.C., United States. A centerpiece of Columbus Circle, Columbus Fountain serves as a tribute to the explorer Christopher Columbus. The unveiling in 1912 was celebrated all over Washington, DC over the course of three days with parades, concerts and fireworks gathering tens of thousands of people from all over the world.

Congress established the Northeast Corridor Commission (the Commission) under Sec. 212 of Public Law 110-432 (Passenger Rail Investment and Improvement Act of 2008) to promote mutual cooperation and planning among owners and operators on the Northeast Corridor (NEC) rail line and to advise the U.S. Congress on Corridor policy and investment needs.

The Holodomor Memorial to Victims of the Ukrainian Famine-Genocide of 1932–1933 was opened in Washington, D.C., United States, on November 7, 2015. Congress approved creation of the Holodomor Memorial in 2006.The memorial was built by the National Park Service and the Ukrainian government to honor the victims of the Ukrainian Famine-Genocide of 1932–33 and to educate the American public.The memorial, designed by Larysa Kurylas, is one of three monuments in Washington, D.C., designed or co-designed by women—the others being the Vietnam Veterans Memorial and the National 9/11 Pentagon Memorial.The memorial is located near the U.S. Capitol building at the intersection of North Capitol Street, Massachusetts Avenue, and F Street N.W. It is diagonal to the Smithsonian's National Postal Museum, about one block from Union Station.

It has been a member of the Historic Hotels of America since 2002, and it was renovated in 2016.

The 1953 Pennsylvania Railroad train wreck occurred on January 15, 1953, when a passenger and mail train from Boston to Washington DC (the Federal) failed to brake sufficiently on its approach to Union Station, Washington, jumping the platform and plunging through the floor of the concourse. There were no deaths, but 43 people were injured. The cause of the accident was a design flaw that allowed a brake-valve to close without human intervention.
