Stadler and the San Bernardino County Transportation Authority (SBCTA) have introduced a new hydrogen-powered train, the Zero Emission Multiple Unit (ZEMU), in San Bernardino, California. The train, utilizing a hybrid hydrogen and battery technology, has arrived at the San Bernardino Depot Train Station for final phase testing, which includes trips on the Arrow line and system checks. SBCTA President, Ray Marquez, expressed enthusiasm for the greener rail system and innovative transportation solutions that the ZEMU represents for San Bernardino County residents. The project, a result of 10 years of planning and four years of train development, aims to offer efficient and sustainable passenger rail travel. California's Department of Transportation has ordered six hydrogen passenger trains from Stadler to further support eco-friendly transit options. Stadler's FLIRT H2 locomotive, previously used in Colorado, set a Guinness World Record for the longest distance travelled by a hydrogen-powered train without refueling, demonstrating the reliability and success of hydrogen technology in transportation.
