Trains: The Next U.S. Interstate

"Winglock, gridlock. Shrinking mobility, rising pollution. With airport congestion provoking travelers, gas prices agitating drivers, and six-hour rush hours in some cities, alternatives to auto-air dominance have gained appeal... Not only in quality of movement, but in quality of the environment, such improved rail could beat the skies and surface roads. As concerns about energy and global warming grow, trains could serve to reduce US greenhouse gas emissions - 33 percent of which come from motor vehicles. Likewise, increased rail use could shrink the mounting airplane emissions in the upper atmosphere, predicted by the Worldwatch Institute to become ever more deadly."
