In this photo taken Wednesday, April 11, 2012, Federal Transit Administrator Peter Rogoff, second from right, and Bay Area Rapid Transit (BART) General Manager Grace Crunican, second from left, and others, stand near a BART train during a tour of the BART Maintenance Yard in Hayward, Calif. Driven by high gas prices and an uncertain economy, Americans are turning to trains and buses to get around in greater numbers than ever before. The aging trains and buses they’re riding, however, face an $80 billion maintenance backlog that jeopardizes service just when it’s most in demand. (AP Photo/Jeff Chiu)
