Full Ethernet Connectivity for Rail

The demand for rail networks such as commuter trains, tramways, subways, light rail, and elevated rail lines is at record levels due to rapid urbanization. Traditionally, railways rely on disparate networks to keep trains rolling forward on tracks. Because of these divergent rail systems, railways incur tangible as well as intangible costs when addressing demands to achieve speed, deliver safe and punctual transportation, and improve passenger experiences.

Moxa is the world's first IRIS-certified manufacturer that provides a complete EN 50155 rugged-railway Ethernet portfolio. Products in this portfolio have been deployed successfully in many rail and metro systems around the world.

With innovative wired, wireless, and firewall routing technologies, Moxa helps railway companies to take advantage of fully integrated Ethernet networks that connect trains to the trackside and all the way back to the control center to achieve overall transport safety, efficiency, and significant cost and time-savings on railway operations and maintenance.

Moxa's EN 50155 Ethernet devices ensure the highest network availability by providing millisecond-fast resilient connections at every level from wired routing, switching to wireless communications within consists on the move, or between the trains and wayside.

Industry-proven Reliability

Moxa’s comprehensive portfolio of rugged-railway switches and wireless devices is designed to withstand harsh environmental conditions, covering wide operating temperature variations, various power input voltages, surges, ESDs, and vibration, making these products highly durable and able to operate in harsh rolling stock and wayside environments.

  • M12 connectors for robust connections
  • Broad fiber-optic portfolio
  • Anti-vibration and high EMI/surge protection
  • -40 to 75 ̊C operating temperature range
  • Dual power with a wide power input range
  • IP-68 for outdoor deployment (optional)

High Speed Performance

High bandwidth is a must for implementing onboard CCTV, passenger-oriented services, and other Ethernet consist networks. In addition, wayside networks require an even larger bandwidth, as they not only need to connect with diverse systems onboard but also need to process and send back the information to the control center. Moxa provides a wide variety of 10GbE, Gigabit, Ethernet, PoE/PoE+, fiber optic, and twisted DSL solutions to facilitate high-speed data communication, simplifying field wiring and reducing installation costs for modern railway applications.

Flexible Train Operations

Updating train networks is time-consuming when train cars are added, removed, or replaced. Moxa's railway devices enable innovative auto-configuration for fast and accurate inter-consist and inter-carriage rearrangement. Saving time by doing away with error-prone manual configuration helps guarantee accuracy and efficiency.

Dynamic Ring Coupling

Moxa’s TN advanced series of Ethernet switches features Dynamic Ring Coupling technology that excels in inter-consist network redundancy. When train carriages are reorganized, Dynamic Ring Coupling detects and automatically reconfigures the network. This technology reduces configuration time and potential human error to achieve highly reliable and efficient train operations.

Auto Carriage Connection

For carriages that are connected wirelessly, Moxa’s Auto Carriage Connection (ACC) feature automatically forms 802.11n wireless bridges between adjacent wireless APs. ACC is available in the 802.11n AWK-RCC series, which supplies up to 300 Mbps of bandwidth to deal with demanding multimedia services.

Easy Deployment and Management

Moxa's MXstudio network management suite makes life easier with a graphic-friendly user interface for network deployment, monitoring, and maintenance. MXconfig assigns IP addresses 10-time faster than one-by-one configuration, making it easier to mass deploy many network devices in a new train system. MXview presents critical network information on a live-view topology that allows non-IT staff to monitor the entire network conditions at a glance.

  • Mass configuration for time-saving and error prevention
  • MXview for live-view topology monitoring
  • Event Playback for easy event tracking
  • Network snapshots for quick troubleshooting
  • Mobile app monitoring and alerts for reduced downtime

Onboard Ethernet
