SIERRA NORTHERN RAILWAY SUCCESSFULLY TESTS FIRST, FOUR AXLE HYDROGEN FUELED ZERO EMISSION SWITCHING LOCOMOTIVE

Sierra Northern Railway (SERA) announced today at the American Short Line and Regional Railroad Association (ASLRRA) conference in Denver, Colorado, that it successfully completed testing of the first four-axle hydrogen-fueled, zero-emission switching locomotive on March 27, 2025, in West Sacramento, California.

Demonstration and validation of Sierra Northern Railways Hydrogen Powered Zero Emission Switcher Locomotive establishes a platform for widespread commercialization in the immediate future. Short line and switching locomotives account for a significant share of the total locomotive energy use within the State of California as they carry a significant portion of freight in California and operate on the first and last miles of the national freight network. This makes short-line operations an excellent testbed for the demonstration of zero-emission technologies and a key to decarbonizing transportation emissions.

Most switcher locomotives in California use an average of approximately 50,000 gallons per year per switcher, potentially leading to a reduction of more than 12 million gallons of diesel per year. This is approximately equivalent to the same amount of fuel used each year by 20,000 light-duty vehicles.

In addition to the funds received by the California Energy Commission, Sierra’s funding partners include: The Sacramento Metropolitan Air Quality District, SoCalGas and the Low Carbon Resource Initiative. Project Partners include: GTI Energy, Velocity Strategies, Railpower Tech, WHA International, Inc., OptiFuel Systems, Ballard Power Systems, UC Riverside and Valley Vision.

Sierra Northern Railway has already started the process to build three additional zero emission hydrogen fueled switching locomotive from funding it was awarded from the State of California, California State Transportation Agency, Port and Freight Infrastructure Project Funding through a public-private partnership with the Sacramento Metropolitan Air Quality Management District. The total project cost will be approximately $19,500,000 to expand on its current efforts by developing, demonstrating, and testing three additional hydrogen-fueled, zero-emissions switcher locomotives. The testing will be conducted on the soon to be constructed test track in Sierra’s West Sacramento rail yard. When this project is completed in quarter four of 2027, it will expand the Sierra’s Hydrogen Zero Emission Switching Locomotive Fleet to a total of four locomotives.
