Florida is at the forefront of the nation's high-speed rail boom, with its bullet train slated to be complete in 2015. But will the state's high-speed rail attract enough riders to be declared a success? If Florida fails, it could imperil other states' plans. Right now, Iowa and Illinois are applying jointly for $248 million in federal funds to build high-speed rail, while Texas is just beginning to talk about it. Meanwhile, University of Pennsylvania graduate students have invented a plan to transform Amtrak's Northeast Corridor into a true high-speed railway.
