Final answer:
Amtrak, the National Railroad Passenger Corporation, offers discounts on one-way coach fares as part of its service to make train travel accessible and affordable. While the exact discount may vary, it is a reflection of efforts to maintain passenger rail service despite financial challenges in the industry.
Step-by-step explanation:
Amtrak provides a passenger rail service across the United States, known for its various discount programs that help make train travel more affordable. While the exact discount offered on one-way coach fares to specific demographics such as seniors, students, military personnel, or children may vary, it is typically intended to keep train travel as a viable option even as profits are not as strong as in the past. In 1971, due to the combination of the public's preference for travel by air and car, along with declining profits of private railway companies, the U.S. government consolidated the remaining railway lines into the National Railroad Passenger Corporation, commonly known as Amtrak. This consolidation was an effort to ensure that train travel would remain an available option for those who prefer or rely on it, like individuals with a limited budget who enjoy traveling.
