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

Published

on

WEST SACRAMENTO, Calif., April 8, 2025 /PRNewswire/ — 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.

This demonstration will start to facilitate the improvement of local air quality, a reduction in greenhouse gas emissions, noise, and odor for the communities that have a short line in their community. 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.

“Sierra Northern Railway is proud that we will continue to lead the industry with low emission switching solutions as we continue to demonstrate that Sierra has achieved what the industry needs to convert to zero emission by integrating advanced hydrogen fuel cells, hydrogen storage, advanced battery and systems control technologies to provide an alternative to less environmentally friendly diesel-powered locomotives.” stated Beard.

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.

Next Actions for Sierra Northern Railway

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 and will help Sierra lead the way to eventually convert the entire Sierra fleet to hydrogen powered zero-emission switchers as well as all 260+ switchers in California to a Sierra Hydrogen Powered Zero Emission Switcher Locomotive.

Sierra Northern Railway (SERA): Sierra Northern Railway is the freight division of privately owned, Sierra Railroad Company. Sierra Railroad Company is also the principal owner of Sierra Energy Corporation, which has developed a proprietary waste- to- clean hydrogen technology: FastOx® gasification. Sierra Northern Railway currently operates approximately 75 miles of track in Northern California and 30 miles in Southern California through the heart of a number of the Golden State’s prime industrial areas, serving a wide variety of customers, and interchanging with both BNSF Railway and Union Pacific Railroad.  http://sierranorthern.com

Weeklong Conference Celebrates 53 Years of Advancing the State of the Art in Computer Graphics and Interactive Techniques

LOS ANGELES, July 23, 2026 /PRNewswire/ — The 53rd annual SIGGRAPH conference, the world’s premier conference on computer graphics and interactive techniques, brought together thousands of artists, researchers, developers, and industry leaders from around the globe this week at the Los Angeles Convention Center. From an inspiring keynote by legendary Disney Imagineer Lanny Smoot and the debut of the Games Summit to advancements in artificial intelligence (AI), robotics, neural rendering, Gaussian splatting, and immersive storytelling, SIGGRAPH 2026 reaffirmed its role as the global stage where research meets production and ideas shape the future of the field.

SIGGRAPH 2026 welcomed an international audience of more than 9,500 people from 69 countries, alongside a bustling exhibition floor where companies large and small showcased the latest in computer graphics and interactive techniques, products, and services.

“SIGGRAPH 2026 showed what happens when the world’s technical and creative communities share one space. The lines between computer graphics, physics, and AI are blurring, and this week our attendees turned that convergence into new collaborations, research directions, and ways to tell stories,” said SIGGRAPH 2026 Conference Chair Chris Redmann. “From our first Games Summit to a keynote that reminded us invention is a team sport, this conference celebrated the breakthroughs of today while laying the groundwork for the future of our field.”

A highlight of the week came Monday, 20 July, when Disney Research Fellow and Walt Disney Imagineering inventor Lanny Smoot took the keynote stage with “Inventions, Innovations, and Imagination: Lanny Smoot’s Prolific Path”. Smoot, who holds 107 patents and in 2024 became only the second Disney employee after Walt Disney himself to be inducted into the National Inventors Hall of Fame, traced a career spanning more than 45 years, from Bell Labs breakthroughs to beloved Disney Parks innovations including the HoloTile floor and the extendable lightsaber. His message that successful technical practitioners love to create and want to learn from others resonated with a packed house of attendees at the start of the conference week.

Keynote programming continued throughout the week with three standout sponsored sessions. NVIDIA research and engineering leaders Neil Ashton, Ming-Yu Liu, and Edward Liu explored the next era of graphics through neural rendering, world models, and AI-driven simulation. Bolt Graphics founder Darwesh Singh shared his vision for a GPU architecture built for real-time path tracing, and the research team behind Tripo AI examined how generative 3D is redefining how digital worlds are made.

AI ran through nearly every program at SIGGRAPH 2026, positioned not as a replacement for human creativity but as a creative partner. Technical Papers, Technical Workshops, Courses, and Birds of a Feather sessions connected researchers and production artists on generative workflows, differentiable physics, and world models. NVIDIA dedicated a full day to physical AI, presented 21 papers connecting 3D worlds and robot control, and drew industry-wide conversation with a technical deep dive into DLSS 5 neural rendering.

The inaugural Games Summit brought dedicated programming for game developers to SIGGRAPH. Sessions spanned motion sickness accessibility, destruction systems, performance capture pipelines, and cross-industry collaboration through OpenUSD. Robotics also took center stage across the conference, from research in simulation and motion control to the crowd-favorite Robo Dojo, where attendees guided robots through an immersive training ground on the exhibition floor.

In the Experience Hall, five interactive programs: Spatial Storytelling, the Immersive Pavilion, the Art Gallery, and Emerging Technologies, along with the in-person Hands-On Courses track of the Courses program, had attendees step inside the future of interaction and storytelling. Installations spanned AI-driven art, mixed reality sport, embodied robotics, and spatial narratives of wildfire and memory, while lively discussions on Gaussian splatting explored the future of photorealistic virtual reality.

The Computer Animation Festival, an Academy Award® Qualifying Festival for the “Best in Show” prize, celebrated global storytelling in the Electronic Theater, newly expanded in 2026 to include films longer than 10 minutes, opening the festival to a wider range of filmmakers and formats than ever before. Production Sessions took audiences behind the scenes of “Avatar: Fire and Ash” with Wētā FX and Lightstorm Entertainment, NASA’s “Visualizing the Moon for Artemis II”, Disney and Pixar Animation Studios’ “Hoppers”, and Industrial Light & Magic’s work on “The Mandalorian and Grogu”.
