apr 9, 2025 - (US) Sierra Northern Railway Successfully Tests First, Four Axle Hydrogen Fueled Zero Emission Switching Locomotive

Description:

WEST SACRAMENTO, Calif -- 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.

Kennan H. Beard III, President of Sierra Northern Railway stated, "This accomplishment marks another major milestone in Sierra's mission to bring Hydrogen Powered Zero Emission Switcher Locomotives within commercial reach for the short line industry. Both in California and around the world."



The demonstration of this Hydrogen Powered Zero Emission Switcher Locomotive was funded through a $4,000,000 grant to fund the design, integration, and demonstration of a hydrogen fuel cell switching locomotive from the California Energy Commission (CEC) and administered through GTI Energy.

"Sierra's successful test proves that short lines can retire pre-tier 0 to tier 4 diesel locomotives and replace them with a Hydrogen Powered Zero Emission Switcher Locomotives using our advanced hydrogen powered units," said Beard.

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.
