The U.S. has launched its first hydrogen-powered passenger train, the Stadler Flirt H2, now running on California’s Arrow Line between San Bernardino and Redlands. Meeting Federal Railroad Administration standards, the train offers zero-emission travel, 116 seats, and a 30-minute refueling time. Capable of 460 km per refill, it also holds a Guinness World Record for covering 2,803 km without refueling, signaling a major step toward sustainable public transport nationwide.
