A high speed rail network might be a good start:

Meanwhile, here in the United States, we talk a lot but do very little. California passed an initial bond issue for high-speed rail in November, but even if the project goes ahead, you aren’t likely to be able to ride it until well into the next decade. Citizen groups in the Midwest are pushing for several projects, although they would concentrate on upgrading existing lines for top speeds of around 110 to 125 miles per hour – well below the current European and Japanese standards – rather than genuine high-speed travel.
Proposed Amtrak funding also calls for "study" of high-speed rail, but the time between study and getting on a train is apt to be measured in decades rather than years. Of course, there’s always the possibility that a big economic stimulus package could speed up rail developments, but I’m not holding my breath.
