Opened  on  October, 27,  1907 and pleted in 1908, Union Station (联盟火车站) is considered to be one of the finest examples of the Beaux-Arts (古典装饰的)  style of architecture.  Architect Daniel Buraham designed the building.
At the time it was built, Union Station covered more ground than any other buildings in the United States and was the largest train station in the world.  In many ways, Union Station was a city within a city. At various times it employed a staff of over 5,000 people and provided hotel, ice house, first-class restaurant and police station.
As train travel was the means of transportation for even US Presidents in the early 1900s, a Presidential Suite (总统套间)  was added to Union Station. In 1909, President Taft was the first President to use the room and over the years many famous people were officially weled there. The last President to use the Presidential Suite was President Eisenhower.
For half a century and through two world wars, Union Station served Washington and the US as a major center of transportation and the place for many historic events.  On April 14, 1945,  a train backed into Union Station carrying the casket (棺材) of President Franklin Delano Roosevelt.
However, the air travel led to a decline in railroad passengers, and Union Station began to fall into disuse. In 1968, the decision was made to change it into the National Visitor Center. The project opened in July 4, 1976 but failed to draw enough crowds to sustain（=keep up） its operation, and was closed in 1978.
While Congress debated the future of Union Station, rain damage caused parts of the roof to fall down. Following three years of repair at a cost of $160 million, Union Station reopened on September 29, 1988.
Today, Union Station continues to make history as the most visited place with over 29 million visitors a year. World-class exhibitions and international cultural events are hosted there for the public to enjoy. Private special events are celebrated in the grand halls. Even today, US Presidents still visit Union Station.
