The bullet train would run on new elevated tracks along one of two undisclosed public routes that would not require razing any homes, Daley said. But it's unclear who would pay for it and whether it would work in Chicago. "It has to go from the downtown area right to the airport, and you process everything downtown," Daley said. "You go through one security check. The train is completely secured. It goes right to the airport. And you go right up to the plane."
