Hydrogen Trains Push Innovation and Safety in U.S. Rail

Hydrogen Trains are reshaping U.S. rail transportation, but adopting this technology requires rethinking infrastructure, retraining staff, and redesigning systems to meet new safety and operational standards. This is reported by the railway transport news portal Railway Supply.

At the APTA Rail Conference, leaders from Jacobs, HDR, Ricardo LLC, and SBCTA explored the readiness of Hydrogen Trains. Moderator Jackson Xue opened with questions about real-world challenges for adopting fuel cell technology.

Martin Schroeder of Jacobs stressed that hydrogen isn’t just a cleaner fuel—it behaves differently. Tunnels, refueling, and maintenance operations all need upgrades, since hydrogen is flammable and requires controlled storage.

HDR’s Marcin Taraszkiewicz noted that many Hydrogen Trains, like Stadler’s FLIRT H2, were originally built for Europe. U.S. versions need adaptations for different grades, rules, and environmental conditions.

Hydrogen Trains Demand Purpose-Built Infrastructure

SBCTA leads the U.S. in hydrogen rail deployment with its FLIRT H2 train set to launch in August 2025. The agency built a custom facility for maintenance and hydrogen fueling.

Joy Buenaflor of SBCTA emphasized the project’s scale—it required more than choosing a clean train. She highlighted new safety designs, staff training, and updated ventilation systems for tunnels and depots.

The facility includes deflagration panels, gas detectors, and automatic shutoff systems. These safety elements were designed from the ground up to handle the properties of hydrogen safely and efficiently.

Training and Safety Planning for Hydrogen Trains

Tunnel safety remains a key focus. Schroeder discussed airflow simulations showing how hydrogen disperses during leaks, especially in sloped or confined tunnels. Proper ventilation can reduce ignition risk.

Marcin Taraszkiewicz explained that fire departments need training on how to approach hydrogen-powered units safely. These trains are not more dangerous than diesel—just different in emergency situations.

Buenaflor added that SBCTA began working with local responders early. Familiarity with facilities, valves, and tunnel systems ensures that emergencies are handled quickly and safely.

Hydrogen Trains offer real promise for decarbonizing American rail. But the transition depends on strategy, planning, and infrastructure—not just clean technology alone.
