About Washington Union Station
Washington Union Station, which locals call Union Station, serves the capital as a major rail station, transportation hub and leisure destination. Daniel Burnham designed it. It is the southern end of the Northeast Corridor, an electrified line that reaches Boston by way of Baltimore, Philadelphia and New York City, and the busiest passenger rail route in the country. Union Station is also intermodal: MARC and VRE commuter trains, the Washington Metro, intercity buses and local Metrobus routes all use it.
In 1901 the Pennsylvania Railroad and the B&O (the Baltimore and Ohio Railroad) agreed to jointly build a new union station. Moving their trackwork and terminals off the National Mall allowed the Mall to be created in its modern form. Daniel Burnham guided the design, and William Pierce Anderson of D.H. Burnham & Company was the main designer of the building. Congress passed an act, signed on February 28, 1903 by Theodore Roosevelt, calling for a "monumental in character" station costing at least $4 million. The main building eventually cost more than $5.9 million. No other railroad station in the nation was specifically authorized by Congress.
The first B&O train with passengers arrived on October 27, 1907, and the main building was finished in 1908. The station then had 32 tracks: 23 came in from the northeast and ended at the headhouse, and 9 ran below ground to the south through a tunnel under Capitol Hill. A Presidential Suite, first used by William Howard Taft in 1909, became a U.S.O. canteen in December 1941. World War II brought the heaviest traffic, with up to 200,000 passengers in one day.
