The National Railroad Passenger Corporation, doing business as Amtrak, is the national passenger railroad company of the United States. It operates inter-city rail service in 46 of the 48 contiguous U.S. states and three Canadian provinces. Amtrak is a portmanteau of the words America and trak, the latter itself a sensational spelling of track.
