The nation’s first hydrogen-powered passenger train will begin operations Saturday, Sept. 13, on Metrolink’s Arrow line between Redlands and San Bernardino.
The San Bernardino County Transportation Authority announced the launch of the Zero-Emission Multiple Unit, or ZEMU, earlier in September after about 10 months of testing on the Arrow route. The hybrid passenger train utilizes hydrogen fuel cell and battery electric technology to move itself and power onboard electrical systems. Water vapor is the only emission from the propulsion system.
ZEMU will depart the Metrolink Downtown Station in San Bernardino at 10:32 a.m. Saturday, Sept. 13, marking its debut in passenger service. The train will serve riders on the 9-mile Arrow route only, carrying passengers between downtown San Bernardino and the University of Redlands.
