A brief description of that company.
AMTRAK

The National Railroad Passenger Corporation, better known as Amtrak, is the United States' national rail passenger service, providing train transportation between major cities as well as commuter service to more than 24 million passengers a year in 46 states (Wyoming, South Dakota, Alaska, and Hawaii are excluded) in addition to delivery of mail and express freight. A private corporation, Amtrak is almost wholly owned by the U.S. Department of Transportation.

{A background for the organization}
On May 1, 1971, the first passenger trains operated by the National Railroad Passenger Corporation pulled out of stations around the country, beginning what was depicted as a two-year federal undertaking to revive (and save) long-distance, intercity rail passenger service in the United States.
Congress had created the company the previous year with the passage of the Railroad Passenger Service Act. The Act established a private company, incorporated in the District of Columbia. Most of the new company's stock was owned by the Department of Transportation, and it was governed by a board of directors made up of the Secretary of Transportation, the head of the corporation, and 11 other members, the majority appointed by the president. During its first year of existence, the corporation was known as Railpax. After it began operations, the nickname changed to Amtrak, a contraction of the words America and track.
Amtrak was charged with accomplishing three goals, described in the Amtrak Source Book as: "To operate rail passenger service on a for-profit basis; to use innovative operating and marketing concepts to fully develop the potential of modern railway passenger service to meet intercity transportation needs; and to provide a modern, efficient intercity rail passenger service." Congress authorized grants of $40 million for operations and loan guarantees of $100 million for new equipment. Direct funding was to last only two years, by which time the corporation was to be completely self-supporting.
