U.S. President Barack Obama on Thursday asked for a revamp of the country's train systems, calling for a move towards a system of high-speed rail travel, saying it will relieve congestion, help clean the air and save on energy. Appearing with Vice President Joe Biden and Transportation Secretary Ray LaHood, Obama, who made his comments in Washington before heading to Mexico later in the day to discuss the boarder and drug crises, said the country now cannot afford not to invest in a major upgrade to rail travel. He said he understands it necessarily will be “a long-term project” but said the time to start is now. Obama said that “this is not some fanciful, pie-in-the-sky vision of the future. It's happening now. The problem is, it's happening elsewhere.” He cited superior high-speed rail travel in countries like China, Japan, France and Spain. Obama said the rail upgrades are critically needed because the nation's highways and airways “are clogged with traffic.”
