ORing's Networking Solution for Railway

ORing’s Networking Solution for Railway Applications

Reliability is the top priority for railway networks due to high levels of vibration and EMI in the environment. In addition, deploying railway networks is increasingly complicated and difficult since modern railway systems are experiencing more traffic, higher speeds, and longer trains. Operators not only have to ensure uninterrupted connections during train movement but also reconfigure networks as soon as possible when changing train carriages. As an approved partner for highly available data communication solutions on trains and along railroad tracks, ORing’s railway networking solution offers the following advantages.

Application

Onboard

ORing’s Transporter-series complies with EN50155 standard and is a perfect fit for building TCN (Train Communication Network), CCTV, PIS (Passenger Information System) and passenger Wi-Fi networks.

ORing’s railway network solution supports up to 16 PoE ports and can power several PDs at the same time, thus simplifying cabling and management.

With IEC 61375-2-5 TTDP and IEC 61375-2-3 TRDP support, ORing’s TGRS-T120 -M12X-BP2-WV will reassign IP addresses automatically and enable data to be transmitted through the TBN (Train Backbone Node) by R-NAT, thus facilitating dynamic changes of train topology.

Train to Ground

Data transmission between the train and ground facility is realized via wireless connectivity. When a train approaches or stops at the station, the wireless router’s transmission mode will shift from cellular to Wi-Fi to save data transmission costs.

ORing’s 4G/5G routers support dual SIMs which will switch to the backup ISP automatically when the primary ISP fails, thus minimizing the risk of downtime.

ORing’s cellular routers installed in the train can transmit data such as monitoring logs, driving records, and ATP to the cloud. They can also be integrated with AI systems to enable remote management and big data analysis.

Wayside

Trackside and onboard devices need to exchange data in real time via wayside networks, so building a secure and reliable wayside network is necessary.

All of ORing’s managed switches provide network redundancy in a ring topology, which supports millisecond-level fast recovery when any node in the ring fails. Some models provide 10Gb/s uplinks for building backbone networks.

Models with Q-ODC interfaces can support fiber connections up to 550 meters. With immunity to electromagnetic interference, fiber-optic cables are perfect for long-distance wayside data transmissions.
