The San Bernardino County Transportation Authority (SBCTA) begins Phase II testing of North America’s first hydrogen passenger train. The zero-emission multiple unit (ZEMU) trainset represents a breakthrough in sustainable rail transportation. Testing will commence on November 12, 2024, on Metrolink’s Arrow Corridor.
Key Testing Details
- Location: 9-mile Arrow Corridor between San Bernardino and Redlands, California
- Schedule: Weekday nights, 9 PM to 4 AM through January 2025
- Testing Focus: Operational performance validation
- Infrastructure: First hydrogen fueling station for rail vehicles in Southern California
Advanced Propulsion Technology
Swiss manufacturer Stadler built the ZEMU trainset as part of their innovative FLIRT H2 series. The train features state-of-the-art technology that combines hydrogen fuel cells with advanced battery systems. This revolutionary propulsion system produces zero emissions, with water vapor as the only byproduct. The hybrid technology proves that zero-emission solutions can work effectively in heavy rail transportation.
Project Development Timeline
The SBCTA’s journey toward hydrogen-powered trains began with the Stadler contract signing in 2019. The trainset made its global debut at the prestigious InnoTrans Berlin exhibition in 2022. It arrived in the United States in 2023 for initial evaluation procedures. The Federal Railroad Administration’s Transportation Technology Center in Colorado conducted extensive testing protocols. The train finally reached its California destination in June 2024, ready for operational testing.
Testing Requirements and Infrastructure
SBCTA’s Chief of Legislative and Public Affairs, Tim Watkins, outlined the comprehensive testing approach. The ZEMU testing follows standard DMU procedures while accounting for unique vehicle specifications. The Arrow Maintenance Facility requires significant modifications to support hydrogen operations. These changes include installing specialized hydrogen storage systems and advanced fueling capabilities.
Facility Development and Safety Measures
The project encompasses more than just the testing of revolutionary train technology. SBCTA is constructing Southern California’s first hydrogen fueling station dedicated to rail vehicles. The new facility will set industry standards for hydrogen rail operations. Every safety measure follows strict federal guidelines for hydrogen storage and handling.
North American Context
This project marks the first permanent deployment of hydrogen passenger trains in the United States. Similar technology underwent successful testing through a three-month program in Quebec. The Quebec trials demonstrated growing interest in hydrogen-powered rail solutions across North America. Each successful test brings hydrogen rail technology closer to widespread adoption.
Future Impact and Implementation
The SBCTA initiative will serve as a blueprint for future zero-emission rail projects. Passenger service is scheduled to begin in early 2025, positioning California as a leader. This project demonstrates the practical application of sustainable transportation technology. The success of these hydrogen-powered trains could reshape American public transit. Transportation authorities nationwide are closely watching this groundbreaking implementation.
Infrastructure Legacy
The project creates lasting infrastructure for future hydrogen rail operations in Southern California. New fueling and maintenance facilities will support the next generation of clean transit. Local communities will benefit from reduced emissions and quieter train operations. This initiative establishes a foundation for expanding hydrogen rail technology across the region.
