North America’s first federally compliant self-powered, zero-emission passenger train arrived in San Bernardino County on June 20. The train’s arrival at the San Bernardino Depot Train Station marks a significant milestone on its incredible journey from concept to reality. The passenger train, a Zero Emission Multiple Unit (ZEMU), uses a hybrid hydrogen and battery technology to propel the train and power onboard electrical systems. Water vapor is the only emission generated from the propulsion system, making this a clean transit alternative.
The new ZEMU is easy to spot with its signature blue and white water-vapor design wrapped around the train’s two passenger cars and center power pack where the hydrogen and battery propulsion system is located. In the coming weeks, ZEMU will begin the final phase of testing that will include trips on the Arrow line and Metrolink system checks with a goal of safe entry into service later this year.
SBCTA is leading the charge for a greener passenger rail future by piloting zero-emission rail technology for the new Arrow service between San Bernardino and Redlands.
A contract signing in 2019 between Stadler US and SBCTA cleared the path to begin the manufacturing of the first two-car hydrogen-powered passenger train to operate in the United States. Providing a hydrogen-powered rail vehicle to passengers is a critical milestone demonstrating SBCTA’s investment in the county’s sustainable future, zero-emission transportation options and the transition away from using fossil fuels to protect the health of its 2.1 million residents and visitors.
To support the operations of the ZEMU vehicle, specific upgrades and modifications are required to the existing Arrow Maintenance Facility to facilitate hydrogen storage, refueling and required safety enhancements. Construction of the storage and fueling facility is expected to begin in 2024.
ZEMU will offer passengers the most environmentally rail friendly vehicle in the United States and deliver a balanced and sustainable transportation system for San Bernardino County’s future.
