Introduction
To make trains safer and more efficient, European rail operators are prioritizing Remote Train Operation (RTO), a key research area for future autonomous operations. This EU-funded FP2-R2DATO project aims for GoA4-level automation by 2030.
Mission-critical security, low-latency train-to-ground (T2G) communication, and unified virtualized onboard computing are essential technical elements for the program. A leading EU train builder selected Moxa to provide the networking and computing technologies, positioning Moxa as a key partner in Europe’s journey towards full automation.
System Requirements
Considering customer goals and the Europe’s Rail FP2-R2DATO framework, the RTO architecture needed a technical foundation that allows for:
-
- Mission-critical, low-latency T2G communications: A highly reliable communication layer capable of using 5G and Wi-Fi 6 to transmit mission-critical videos, telemetry, and control commands for remote train operations
- Virtualized onboard computing for multiple applications: A secure platform that consolidates multiple essential applications on a single host through virtualization, reducing hardware complexity and improving manageability.
- Dedicated real-time video processing and streaming: A video processing platform supported by dedicated hardware to ensure low screen-to-screen latency, crucial for achieving a remote operation quality similar to local driving, from capture to transmission.
- Cyber-resilience and safety compliance: An architecture that can withstand cyberthreats, aligned with Europe's rail cybersecurity expectations and supporting ATO/CBTC-compatible communication practices.

Customized T2G Secure Computing Platform
2. Cyber-resilient T2G networks and backbones
The architecture ensured low-latency, mission-critical train-to-ground (T2G) communication by combining hardware with advanced connectivity features to support remote train operations.
- The computing platform support simultaneous 5G and Wi-Fi 6 links for stable, high-speed T2G communication, crucial for real-time remote train operations.
- The network backbone uses high-resilience, high-port-density Ethernet switches to form a secure redundant backbone. These switches enable the segmentation of critical and non-critical systems and are IEC 62443-4-2 SL2 certified, ensuring a robust security foundation for compliance with Europe’s strict NIS2/CRA security standards.
