Amtrak unveiled a $117 billion plan to upgrade its high-speed rail service on the East Coast. It's a 30-year vision to increase speeds to up to 220 mph between cities such as Philadelphia, Boston, New York and Washington, D.C. Under the plan, Amtrak would need $4.7 billion a year for 25 years. High-speed passenger service would reduce congestion on roadways and airlines. "No one should take a plane for a trip shorter than 500 miles," said Pennsylvania Gov. Ed Rendell.
