Enabling EU Autonomous Train Research With Collaboration From Key Train Builder
Application Remote Train Operation (RTO) Research
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.

Remote Train Operation: A Step Towards Autonomous Trains, CAF
Moxa delivered an efficient, secure, and streamlined onboard core for the RTO architecture, achieving significant system consolidation:
High-performance virtualization core and customized gateway integration
Customized secure gateway software powers a customized T2G secure computing platform. This feature drastically reduced the hardware footprint and maintenance complexity.
Customized secure gateway software development: Contributing to the development of secure gateway software with integrated switching, routing, firewall, and virtual machine management capabilities.
Maximum system consolidation: Enabling multi-application (e.g., high-load NVR/CCTV processing, IDS/IPS, OS) integration on a single host.
Customized T2G Secure Computing Platform
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.
Secure, Virtualized Architecture for Flagship RTO
Moxa was selected as a strategic partner because of its highly integrated, cyber-resilient solution tailored for the demanding RTO environment. Its value proposition centered on:
Verifiable security assurance The network backbone switch, formally certified to IEC 62443-4-2 SL2, provided a robust and verifiable security foundation. This compliance greatly reduced project risk and met strict EU laws.
Strategic partnership and custom software capability With more than 15 years of proven EU rail project reliability, Moxa’s engineering supported provided complex, customized, secure gateway software, ensuring a solution perfectly suited to the client’s needs.
Expert consolidation for cost and complexity reduction Moxa used virtualization to replace a costly multi-device setup with a single, powerful computing core, shrinking the hardware footprint and cutting the overall Total Cost of Ownership (TCO).
TN-4500B Series
EN 50155 8-port to 28-port Ethernet managed switches with up to 16 Gigabit ports and up to 24 PoE ports
Railway fanless x86 computers with 11th Gen Intel® Core™ processor, 5G and Wi-Fi 6 support, 2 hot-swappable HDD/SSD slots with lock, -40 to 70°C operating temperature (EN 50155 OT4)
