Final answer:
Congress passed legislation that led to the formation of Amtrak to support the failing passenger rail service industry.
Step-by-step explanation:
When faced with a possible collapse of the rail industry, Congress passed legislation leading to the creation of the National Railroad Passenger Corporation, better known by its trade name Amtrak. This was a significant move to consolidate the remaining lines of passenger rail service which were facing dwindling profits. The creation of Amtrak was an important governmental step to ensure the continuation and stabilization of passenger rail service in the United States. Other legislative actions over the years to support the rail industry have included the Interstate Commerce Act, the Hepburn Act, and during wartime, the establishment of the U.S. Railroad Administration to manage the rail system more effectively.
