Integration of edge computing in railway infrastructure

ADLINK Technology Inc. is collaborating with display technology providers to deploy edge inference computing and onboard passenger information systems for the railway industry. This technical integration focuses on modernizing digital infrastructure across rail networks and transit hubs.

Operational Challenges and Collaboration
The global rail industry requires continuous operational stability, autonomous obstacle detection, and predictive maintenance within harsh environmental conditions. To address these infrastructural challenges, ADLINK Technology Inc. collaborates with AUO Display Plus and system integrators. This cooperation combines high-performance edge computing with specialized display hardware to establish a dependable digital backbone, bridging the gap between moving vehicles and central management in smart railway networks.

Technical Solution and Responsibilities
The technical architecture is built around the AVA-7200 rugged artificial intelligence inference platform, which complies with EN 50155 standards for railway environments. ADLINK engineers the computing hardware utilizing Intel processors and embedded graphics processing units to deliver real-time vision processing. AUO Display Plus provides the panel technology for the unified onboard passenger information systems. These hardware components are combined with Serial systems, integrating central processing units and versatile input/output modules into rugged chassis configurations to support Train Control and Management Systems and Automatic Train Operation platforms.

Deployment and Implementation
The physical deployment and demonstration of these intelligent systems take place at the InnoTrans trade fair at Messe Berlin in Germany from September 22 to 25, 2026. During implementation in operational rail networks, the onboard passenger information architecture integrates with local content servers and 5G gateways. This configuration enables low-latency telemetry and seamless failover connectivity, ensuring that the digital infrastructure remains active during transit. Trackside deployment includes solar-compatible 13.3-inch and 40-inch ePaper solutions that minimize power consumption at station platforms.

Applications and Use Cases
These edge computing technologies are applied directly to railway operations, wayside signaling, and transit hub management. Functional use cases involve accelerating autonomous obstacle detection and facilitating automated passenger updates through 49.5-inch stretched overhead sign displays. The application of this digital infrastructure stabilizes real-time data processing and supports predictive maintenance strategies, reducing the likelihood of unexpected system failures in high-density operational environments.

Results and Expected Impact
The integration of rugged edge computing and advanced display systems secures continuous data transmission and high-visibility signage for railway operators. The utilization of ultra-low power ePaper solutions effectively resolves power supply limitations at outdoor platform locations. Regarding the technological transition, Ryan Chiu, VP of ADLINK DMS+ and Rugged Computing BU, states: "As the global rail industry transitions toward higher automation and enhanced passenger expectations, computing at the edge becomes the ultimate enabler." He further details the system architecture: "our EN 50155-compliant NVIDIA-powered computing platforms, resilient 5G gateways, and highly reliable onboard/platform displays work together to form a dependable digital backbone for smart railway networks worldwide."
