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.
Whether their bet pays off will hinge on whether freight railroads and their customers will buy into a new way of operating. Parallel Systems isn’t just taking an existing freight train and swapping its diesel-electric locomotive for a battery version. Instead, it’s taking the traction motors and distributing them to every car on the train. It’s how many electric passenger trains operate, but it’s a system that has been slow to migrate to the freight world.
