Autonomous battery-powered rail cars could steal shipments from truckers

For the last 200 years, freight trains haven’t changed much; massive locomotives still move relatively dumb freight cars. Certainly, rail fans could argue that plenty has changed—they’re not wrong!—but from a distance, trains work pretty much the same today as they did in the 1800s.

That may change, though, if three former SpaceX engineers have placed their bets properly. Today, their startup, Parallel Systems, has emerged from stealth mode with a prototype vehicle that promises to bring advances in autonomy and battery technology to the relatively staid world of freight railroads. In the process, they hope to not just electrify existing routes but also bring freight rail service to places that don’t have it today.

Parallel Systems is going a step further, though. Each of its rail vehicles consists of a battery pack, electric motors, four wheels, and a package of sensors that allow it to operate autonomously. And since a large portion of the world’s freight is shipped via 20-foot containers, Parallel Systems is using the containers themselves to complete the car, bridging the gap between the sets of wheels at either end of a train car, also known as bogies.

Here’s how it works: two vehicles position themselves far enough apart to support the container, which is lowered by a crane. The vehicles then use their short- and long-range cameras to navigate the rails. Because each rail vehicle has everything it needs, it doesn’t have to be part of a long train. In theory, one container supported by two Parallel Systems vehicles could move from origin to destination by itself. In reality, though, they’ll likely end up traveling in platoons. (Parallel Systems doesn’t call them trains because the individual cars aren’t coupled.)
