In 1993, Mike Hart bought his first railroad with a bold vision: to create an emissions-free freight locomotive. More than three decades later, that dream has become reality. At a recent ribbon-cutting ceremony, the first diesel switcher locomotive was officially converted to run on hydrogen fuel cells and compressed hydrogen—marking a historic milestone in clean freight transportation.

This breakthrough is just the beginning. The plan now extends to converting 250+ short-haul switcher locomotives across California, each potentially eliminating the need for 10,000 gallons of diesel fuel every year. Switcher locomotives, which move railcars for loading, unloading, or reorganizing trains, are the perfect starting point for hydrogen rail. Unlike long-haul freight trains that would require extensive fueling infrastructure, switchers can be powered with just a few hydrogen refueling stations located in railyards. A two-hour refuel once a week makes this model both practical and scalable.

The ribbon-cutting event drew nearly 200 people and widespread coverage from major outlets like Fox 40 News and KCRA, underscoring the significance of this clean rail innovation.

Mike Hart is no stranger to pioneering clean technology. He is also behind the FastOx waste gasifier, which produces a hydrogen-rich synthesis gas from municipal waste. Communities and even the military are exploring FastOx for sustainable waste management and clean energy production. Beyond creating methanol, clean diesel, or syngas for power plants, FastOx technology could also generate hydrogen on-site—fueling the very locomotives now being converted.

After decades of development, the pieces are finally coming together: hydrogen locomotives, efficient fueling strategies, and a sustainable hydrogen supply chain. What started as one man’s vision is now a model for zero-emission freight rail—and a step toward transforming how goods move across the country.
