The National Railroad Passenger Corporation, doing business as Amtrak, is a passenger railroad service that provides medium- and long-distance intercity service in the contiguous United States and to nine Canadian cities.
Founded in 1971 as a quasi-public corporation to operate many U.S. passenger rail services, it receives a combination of state and federal subsidies but is managed as a for-profit organization. Amtrak's headquarters is located one block west of Union Station in Washington, D.C.
Amtrak serves more than 500 destinations in 46 states and three Canadian provinces, operating more than 300 trains daily over 21,400 miles (34,000 km) of track. Some track sections allow trains to run as fast as 150 mph (240 km/h).
In fiscal year 2017, Amtrak served 31.7 million passengers and had $3.3 billion in revenue, while employing more than 20,000 people. Nearly 87,000 passengers ride more than 300 Amtrak trains on a daily basis. Nearly two-thirds of passengers come from the 10 largest metropolitan areas; 83% of passengers travel on routes shorter than 400 miles (645 km).
The name Amtrak is a portmanteau of the words America and trak, the latter itself a sensational spelling of track.
