IEC 61375 Onboard Networks Ensure Interoperability and
Standardisation
According to the IEC 61375 standard, the onboard Ethernet Train Backbone (ETB) allows for the
interoperability of consistent subnets regardless of differing network technologies and manufacturers.
Moxa’s Reliability Triangle for IEC 61375 ensures convenient system reconfiguration, easy retrofits,
and built-in cybersecurity so that onboard networks can remain reliable, interoperable, and ready for
the future.

Auto Configuration
Automatically provisions IP configurations across devices, simplifying installation and
accelerating large-scale rollouts.
Flexible Train-to-ground Communications
Cellular and Wi-Fi technologies are now the dominant forms of train-to-ground (T2G) communications. Trains are
trusted to cellular connectivity to continuously send data while in motion, fast-roaming Wi-Fi for
reliable streaming, and station Wi-Fi for copious data offloading at a lower cost. Moxa’s hybrid
T2G solutions provide you with connectivity that never falters and is robustly secure.
Three T2G Scenarios
Fast roaming over Wi-Fi
Data transmission over cellular
Offloading over Wi-Fi at the station/depot
Transmit CCTV and CBTC Data to OCC Over Wi-Fi 6
Scenario
Requires trackside wireless access points every 200 to 300 meters for roaming. Trackside
radios are connected to ruggedised trackside backbone switches through fiber links.
Moxa Solution
The TAP-M310R Series features a modular design with Ethernet switch modules integrated into
the product. It supports multiple Ethernet/Turbo Chain configurations and simplifies
deployment and future upgrades.
Benefits
Resilient, cost-efficient network scalability with easy integration into existing
infrastructure.
Data Transmission Over 5G During Operation
Scenario
Growing demand for ultra-reliable, low-latency, high-speed communication networks.
Moxa Solution
The V3400 Series offers a flexible computer platform supporting both 5G and Wi-Fi 6, functioning as a secure gateway
to host and manage multiple onboard applications.
The V1200 Series features 5G and Wi-Fi 6 wireless capabilities, ideal for essential T2G
applications.
Benefits
A hybrid 5G and Wi-Fi 6 platform enabling safer, faster, and more efficient train control
operations.
Quickly Offloading Recorded Data to Stations or Depots
Over Wi-Fi 6
Scenario
When trains arrive at stations or return to depots, onboard data is offloaded via Wi-Fi.
Moxa Solution
Onboard Wi-Fi 6 clients connect seamlessly to outdoor access points positioned at
stations, transmitting video and operational data from the train to ground systems.
Benefits
A hybrid 5G and Wi-Fi 6 architecture that improves data transfer speed, system
reliability, and overall rail operation safety.
Data-driven Intelligence
As onboard systems grow more connected, modern trains require compact yet high-performance computers
capable of handling real-time monitoring, control, and multi-application workloads. Moxa’s EN
50155-compliant, fanless platforms integrate video streaming, recording, and secure wireless
connectivity—serving as both an intelligent edge computer and a hardened secure gateway. They power
applications such as PIS, CCTV, and operator displays, ensuring stronger cybersecurity, smarter data
handling, and smooth, reliable train operations.
