Stadler and the San Bernardino County Transportation Authority (SBCTA) have unveiled a new hydrogen-powered train intended for local service in California called the FLIRT H2. This Zero Emission Multiple Unit (ZEMU) will replace its diesel-fueled predecessor, operate between San Bernardino and Redlands, and contribute to more sustainable railway operations in the state.
The 108-seated ZEMU train uses a hybrid hydrogen fuel cell and battery technology, converting hydrogen into electricity to power the train and its HVAC system. Green hydrogen is stored in onboard tanks, enabling the train to travel long distances without recharging the batteries.
Transit officials anticipate the ZEMU trainset will become the most environmentally efficient railcar in the U.S. upon deployment. During its testing, the FLIRT H2 was recognized by Guinness World Records for the longest distance traveled by a pilot hydrogen-powered train without refueling or recharging, traveling more than 1,700 miles.
The first of the $23 million railway vehicles is expected to begin passenger operations on the 9-mile route before the end of 2024, with plans to eventually convert the other two Arrow line trains to zero-emission technology. Tim Watkins, spokesperson for SBCTA, highlighted the agency’s vision to transition to a zero-emission fleet.
The project represents a pivotal step in SBCTA’s commitment to reducing its reliance on fossil fuels and protecting the health of its 2.1 million residents and visitors. The achievement is also the culmination of several years of effort by SBCTA to introduce hydrogen-fuel-cell-powered trains. SBCTA President Ray Marquez highlighted its arrival as a significant step in advancing a greener rail system for San Bernardino County.
In February, California’s Department of Transportation placed an additional $127m order for six hydrogen passenger trains from Stadler, supplementing the four hydrogen-powered trains previously ordered. These new hydrogen-powered locomotives are expected to enter revenue in 2027.
