A document will address the role of the Federal Government in financing the operation of the National Railroad Transportation Corporation (AMTRAK).
A relevant document must provide information on the government’s responsibility to make AMTRAK an economically viable entity. It could also discuss the privatization of AMTRAK as an alternative to continuous government subsidies. Documents comparing government subsidies given to air and bus transportation with those provided to AMTRAK would also be relevant.
