Progress unabated: Innovations in electric trainsets powered by batteries for suburban rail networks
In a significant stride towards cleaner and more sustainable transportation, the San Bernardino County Transit Authority (SBCTA) has recently introduced the Stadler Zero Emission Multiple Unit (ZEMU), a hydrogen-powered train. This innovative rail transit solution, which emits only water vapor, is set to revolutionize rail services in the region.
The ZEMU, North America's first federally compliant self-powered, zero-emission passenger train, arrived in San Bernardino County in June 2024. This marks a significant step forward in the adoption of hydrogen-fueled railcars, contributing to cleaner transportation across the continent [3].
The ZEMU is expected to enter commercial service in San Bernardino County sometime in 2025. The county has expressed interest in expanding the use of ZEMUs beyond the Arrow service to the San Bernardino Line, potentially operating all the way to Los Angeles Union Station [2].
The SBCTA has retrofitted a maintenance yard to accommodate hydrogen-fueled rail cars. This includes improvements in ventilation, fire suppression systems, and other safety measures necessary for hydrogen technology [3].
Stadler Rail, a Swiss company, is at the forefront of hydrogen-powered train adoption. They have delivered the U.S.'s first hydrogen train, the FLIRT H2 model, which shares similarities with the ZEMU in its zero-emission capabilities [5].
Battery-electric trainsets are also increasingly being used in North America, offering a minimal infrastructure investment benefit. Battery hybrid trainsets, like the ZEMU, can be paired with various power sources, such as diesel, overhead catenary, third rail electricity, or hydrogen, providing flexibility in operation [1].
These developments underscore significant advancements in sustainable rail transit solutions, with the ZEMU being a key innovation in reducing emissions and modernizing rail services. The topic of dual-mode motive power, including battery hybrid trains, was recently discussed in the January/February issue of a website magazine [4].
