[STC001078] The Rail Passenger Service Act was signed into law by President Nixon in October of 1970. This consolidated 20 existing passenger railroad services into the National Railroad Passenger Corporation, which later became known as Amtrak. On the first of May in 1971, just after midnight, the first official Amtrak service departed from Penn Station in New York City and headed in the direction of Philadelphia. In the years that followed, new routes were rapidly implemented, and today Amtrak runs 33 lines that connect to more than 500 locations across 46 states in the United States and Canada. Amtrak trains carried a record 32.5 million passengers in 2019, breaking the previous record set in 2018.
