A one-time, financial shot in the arm from the federal government won't be enough to make high-speed rail a reality in New York, according to Michael Tucker, president and CEO of the Albany-based Center for Economic Growth. "The key is, it must be sustainable," he said. New York plans to rehab its 263-mile Empire Corridor to accommodate high-speed passenger rail. It's a $3 billion project currently supported by just $151 million in federal money. A bond sale is on the table, among other funding options.
