Parallel Systems—the startup founded by former SpaceX engineers to develop autonomous, electric rail cars for the freight industry—has received a $4.4 million research grant from the U.S. Department of Energy (DOE) to fund advanced testing of its technology.

The funding, part of $175 million awarded by the DOE to nearly 70 clean energy tech projects, comes less than a month after Los Angeles-based Parallel Systems emerged from stealth mode with nearly $50 million in Series A funding.


The startup aims to decarbonize the commercial freight industry by creating autonomous, battery-powered freight cars that can break apart or combine with other cars as needed. By eschewing conventional, diesel-powered locomotives with hundreds of freight cars in tow, Parallel Systems’ technology would allow cargo to be delivered closer to its final destination (rather than having to be transported there via freight trucks) and would reduce the need for switching stations where freight trains are broken apart, reassembled, and rerouted.

While some rail industry experts have expressed skepticism about the technology’s prospects, the DOE appears intrigued nonetheless. The funding comes from the department’s Advanced Research Projects Agency-Energy (ARPA-E) initiative and will bankroll a 29-month testing program beginning this spring.

The program will evaluate the overall vehicle stability, contact-based platooning and energy efficiency of Parallel Systems’ freight cars. On-track testing will be carried out in Pueblo, Colo., in collaboration with Transportation Technology Center (a subsidiary of the American Association of Railroads) and will examine how the cars perform in various physical conditions. The DOE’s National Renewable Energy Laboratory will work with the University of Illinois’ Rail Transportation and Engineering Center (RailTEC) to size up the technology’s company’s energy efficiency and environmental benefits.

However, the tests won’t evaluate Parallel’s ability to integrate its technology into the existing architecture of America’s rail system—the main concern voiced by industry experts after the startup emerged from stealth last month.

How Real-Time Data Is Helping Physicians Track Their Patients, One Heartbeat at a Time

Are you a human node on a health-based digital network?

According to research from Insider Intelligence, the U.S. smart wearable user market is poised to grow 25.5% in 2023. Which is to say, there are an increasing number of Angelenos walking around this city whose vital signs can be tracked day and night via their doctor's digital device. If you've signed up to a health-based portal via a workplace insurance scheme, or through a primary care provider's portal which utilizes Google Fit, you’re one of them.

Do you know your baseline health status and resting heartbeat? Can you track your pulse, and take your own blood pressure? Have you received genetic counseling based on the sequencing of your genome? Do you avoid dairy because it bloats, or because you know you possess the variant that indicates lactose intolerance?

Who Will Win LA's E-scooter Wars?
Evan Xie

Los Angeles — it’s not just beautiful weather, traffic and the Hollywood Walk of Fame — it’s also the largest shared micromobility market in the U.S. with six operators permitted to deploy up to 6,000 vehicles each.

And despite the open market policy, the competition shows no signs of slowing down.
