Could trains become “moving data centers”? — Physical AI can also “work” for social infrastructure: NVIDIA and Hitachi’s outlook (Part 1/2)

At CES 2026, Hitachi and NVIDIA explained how to deploy physical AI across social infrastructure such as railways, power systems, and manufacturing equipment.

NVIDIA outlined a three-stage model of training, simulation, and operations to improve safety and verifiability before real-world deployment.

Hitachi introduced HMAX, which combines operational data, synthetic data, and domain knowledge into an infrastructure-focused AI solution.

The discussion clarified the technical requirements and commercial direction for AI in sectors that demand stronger safety and auditability than generative AI.
