IEC 61375 Onboard Networks Ensure Interoperability and Standardization
IEC 61375 is the new standard for onboard Ethernet train backbone (ETB) to ensure train-wide interoperability between local consist subnets, regardless of their respective network technologies and manufacturers.
Moxa’s Reliability Triangle for IEC 61375 ensures seamless reconfiguration, simplified retrofits, and built-in cybersecurity—keeping train networks connected, secure, and future-ready.
IEC 61375 Onboard Networks Ensure Interoperability and Standardization
Network Security
Security DNA
Secure-by-design development methodology for HW and SW; device security features based on IEC 62443-4-2
Wired Network
Dynamic Ring Coupling (DRC)
Offers Ethernet redundancy between consists without impacting networks during recomposition
Wireless Network
Auto Carriage Connection (ACC)
Automatically creates wireless connections between train cars, which can adapt to train recompositions during operations
Recommendations for an IEC 61375 Cyber-resilient Network
Separating control and information networks physically boosts cybersecurity and redefines application responsibilities.
Benefits
- Isolated networks for higher levels of security.
- Easier to manage and audit network information (e.g., error tracing).
Flexible and Intelligent Network Reconfigurations
Moxa’s onboard switches combine high-density 10GbE/GbE and PoE ports with bypass options to support bandwidth-intensive applications while enabling dynamic train network reconfiguration for maximum operational flexibility.
Dynamic Ring Coupling™ (DRC)
Ensures seamless Ethernet redundancy between consists without disrupting services like CCTV, Wi-Fi, and PIS during midjourney reorientation.
Auto Carriage Connection (ACC)
Creates wireless intercarriage links for retrofitted trains, reducing cabling complexity and supporting flexible consist re-composition.
Auto Configuration
Automatically assigns IP settings to all devices, streamlining installation and large-scale deployments.
