The U.S. presently has thousands of miles of Interstate Highway right-of-ways. Why not build a hi-speed elevated rail system that crosses the U.S. There is usually plenty of room in the medians. If the system is elevated there would be no need for crossing etc. The system could be built with ready-made concrete and steel components that would be easy to construct. These trains could have speeds in excess of 120 MPH. It could also have cars that would transport the family auto. In addition, it could be a public works project that would employ thousands of people similiar to the TVA and the building of the Hoover Dam.
