Key passages:

In its analysis of different zero-emissions rail technologies, Caltrans found that hydrogen trains, powered by onboard fuel cells that convert hydrogen into electricity, had better range and shorter refueling times than battery-electric trains, which function much like electric cars. Hydrogen was also a cheaper power source than overhead wire (or simply “electrification,” in industry parlance), which would cost an estimated $6.8 billion to install on the state’s three main intercity routes.
Electrifying all 144,000 miles of the nation’s freight rail tracks would cost hundreds of billions of dollars, according to a report by the Association of American Railroads (AAR), ..
Caltrans has a long-term plan to dramatically increase rail service and speeds, which might eventually require electrification by overhead wire, also known as a catenary system. But at least for the next couple of decades, the agency believes, hydrogen is the most feasible way to meet the state’s ambitious climate goals. The money, the political will, and the stomach for a fight with the freight railroads and utility companies just aren’t there yet.
