The Golden Fifties refers to the 1950s, a period of economic prosperity in the United States. Amtrak was established in 1971 to take over most intercity passenger rail services in the U.S. from private railroad companies. The document appears to be about the history of passenger rail service in the U.S. during the 1950s and the establishment of Amtrak in the 1970s to address declining ridership and profitability issues faced by private rail companies.
