San Bernardino County has reached a historic milestone in clean transportation with the debut of ZEMU, North America’s first hydrogen-powered passenger train to meet federal safety standards. Officially launched on September 13, the train will serve the nine-mile Arrow Corridor between San Bernardino Downtown and Redlands, offering riders a quieter, cleaner, and more sustainable way to travel.

Manufactured by Swiss company Stadler, ZEMU is powered by a combination of hydrogen fuel cells and batteries, producing only water vapor as emissions. This makes it a groundbreaking step toward reducing greenhouse gases and improving local air quality—especially in a region where environmental sustainability is becoming a growing priority.

The train’s sleek blue-and-white design, decorated with water-vapor graphics, is more than just eye-catching. It represents a major investment in the future of public transit and the county’s role in pioneering innovative solutions to global challenges. Before entering service, ZEMU underwent extensive testing to ensure it met rigorous U.S. safety and performance standards.

Community leaders and transportation officials see the project as a model for the nation. As more cities look for greener transit solutions, San Bernardino County is positioning itself at the forefront of innovation, proving that sustainable infrastructure can also be reliable and accessible.

The launch of ZEMU isn’t just about a new train—it’s about reshaping the way residents think about mobility, sustainability, and the long-term health of our communities. It’s a proud moment for the region and a glimpse into what the future of clean transportation could look like across the country.
