San Bernardino Depot Train Station recently marked a milestone with the arrival of its first hydrogen-powered passenger train, the Zero Emission Multiple Unit (ZEMU).
Built by Stadler in Switzerland, the FLIRT H2 trainset represents a decade of planning and development led by the San Bernardino County Transportation Authority (SBCTA).
The ZEMU’s arrival in Southern California follows more than a decade of planning and four years of development. SBCTA recognized the need for efficient and sustainable transportation solutions early on, integrating the hydrogen train into the regional transportation ecosystem. The culmination of these efforts signifies a major step towards greener rail systems, as highlighted by SBCTA President Ray Marquez.
The ZEMU train uses hybrid hydrogen and battery technology to power its propulsion system and onboard electrical systems. Emitting only water vapor, it stands as a testament to clean energy innovation. Its blue and white design, symbolizing water vapor, underscores this environmentally friendly attribute. As the first Federal Railroad Administration (FRA) compliant hydrogen train in North America, ZEMU is positioned at the forefront of sustainable rail transport.
While ZEMU represents a significant achievement, it is essential to compare it against industry benchmarks. Hydrogen-powered trains are not a new concept globally. For instance, Germany’s Coradia iLint, developed by Alstom, has been operational since 2018 and serves as a benchmark for hydrogen train technology. The Coradia iLint has demonstrated the viability and efficiency of hydrogen trains, setting a high standard for subsequent projects like ZEMU.
Stadler’s FLIRT H2 train has already set a Guinness World Record for traveling the longest distance by a hydrogen-powered electric multiple unit passenger train on a single tank of fuel. This achievement highlights the train’s potential for long-distance travel and efficiency. However, the real test will be its performance in regular service between San Bernardino and Redlands, California.
ZEMU is currently in the final stages of testing, which includes runs on the Arrow line and Metrolink system checks. If successful, the train will begin service later this year. These tests are crucial for ensuring the train’s safety and reliability. The transition from testing to operational status will be a significant indicator of the project’s success.
