Final answer:
Amtrak, the National Railroad Passenger Corporation, is not directly affiliated with the U.S. Postal Service but was created to maintain passenger rail service in response to declining travel by train in the U.S. Both are government entities and their employees often share a public service motivation, but they serve different functions and are separate organizations.
Step-by-step explanation:
Amtrak, officially known as the National Railroad Passenger Corporation, was created by the U.S. government as a response to the decline in passenger rail travel during the 1950s and 1960s. This creation was aimed at maintaining passenger rail service in the face of reduced profitability that made it unsustainable for private rail companies to operate these services alone.
Amtrak is a government corporation, but it is not directly affiliated with the U.S. Postal Service (U.S.P.S.). Although there have been historical instances where trains, including those operated by companies that were later consolidated into Amtrak, were mandated to carry U.S. mail, this does not constitute an affiliation between Amtrak and the U.S.P.S.
The role of Amtrak is to ensure that passenger rail services continue to exist in the United States. It is a distinct entity from the U.S.P.S. which is a separate government organization responsible for providing postal services. However, they have both played roles in supporting federal services at different times in history. While workers for both Amtrak and the U.S.P.S. typically exhibit public service motivation (PSM), they work for different bureaucracy sectors within the government.
