From the Background and Context: "Amtrak--legally the National Railroad Passenger Corporation--was created by the Rail Passenger Service Act of 19701 and began operating in 1971, taking over intercity passenger service from financially distressed private railroad companies. It originally did not own any rail infrastructure, eventually coming to own some assets cast off by bankrupt private railroads. It is operated as a private company and not a government corporation, but the President appoints the members of its Board of Directors and its primary stockholder is the U.S. Department of Transportation (DOT), with a small proportion of common stock held by other railroad companies. Amtrak currently serves over 500 stations in 46 states and the District of Columbia, running over 300 trains per day on a network approximately 22,000 miles long. [...] This report primarily discusses the implications of reauthorizing Amtrak based on long-term trends through the end of FY2019, not its near-term prospects for recovery to pre-pandemic levels of service and performance."
