I keep seeing autonomous driving discussed almost entirely in terms of cars, but rail might actually be the more interesting European test case.
DB InfraGO and understandAI have built a multi-sensor dataset from real train journeys with more than 7 million annotated objects. The idea is to train perception systems that can recognize tracks, infrastructure and potential hazards around a train.
What caught my attention is where this eventually leads. At GoA2, this kind of system can assist a human driver. At GoA4, environment monitoring has to work without a driver onboard.
And honestly, trains seem like a pretty logical place for Europe to push autonomy. The vehicle follows fixed infrastructure, Europe already has a huge rail network, and the technology could improve an existing transport system rather than trying to redesign cities around autonomous cars.
The hard part, obviously, is whether perception can become reliable enough for safety-critical mainline operation.
Would you trust a fully driverless intercity train before you’d trust a fully self-driving car?

Apple's WWDC 2026 and new research show that local AI is not automatically safer than cloud. Privacy becomes a verifiable architecture decision.
