Boldyn Networks (Boldyn), a leading global provider of shared and private network infrastructure, is paving the way for next-generation, data-intensive applications in rail transport with its high-performance private 5G technology.

In a successful trial conducted at the Smart Rail Connectivity Campus (SRCC), a research, development, and testing hub for intelligent rail transport in Annaberg-Buchholz, Germany, Boldyn demonstrated how real-time 5G video transmission can enable autonomous shunting and other advanced rail operations. Boldyn deployed a unique radio network and server infrastructure at the site, enabling realistic testing of digital innovations in railway operations.

High-precision remote control and continuous monitoring enabled by real-time image transmission

Mobile cameras, temporarily attached to the train, delivered live images with a latency of well under 0.2 seconds - an important benchmark for future remote-controlled rail applications. This achievement lays the technical groundwork for supporting safety-critical scenarios. The validated video application unlocks multiple operational possibilities. In the future, it could support remote-controlled shunting, streamline day-to-day processes, and provide live monitoring of hazardous or sensitive areas of track, such as tunnels, bridges and level crossings. Each 5G camera maintains its own radio connection, providing additional security. If one connection weakens temporarily, another automatically takes over, ensuring stable video transmission even under fluctuating network conditions. The mobile cameras can be deployed quickly and flexibly, eliminating the need for costly retrofitting of trains.

Rüdiger Hnyk, Chief Operating Officer of Boldyn Networks Germany, explains: “The tests show that real-time video transmission with extremely low latency is already reliably possible under real operating conditions. As a partner of SRCC, Boldyn is laying a crucial foundation for accelerating the transition of automation applications in rail transport from the testing stage to practical use.”

The SRCC was initiated by Chemnitz University of Technology and the city of Annaberg-Buchholz as a research centre for intelligent rail transport.

Udo Wehner, Managing Director of the SRCC division at Chemnitz University of Technology, explains: “The Annaberg-Buchholz site is ideal for such applications, combining research and practice. Here, ideas can be jointly developed and quickly tested at a conceptual level. With the tests of its innovative video transmission solution, Boldyn has demonstrated that requirements comparable to those of the Road Traffic Remote Control Regulation can be met.

Thomas Parthum, Manager Partner Network at SRCCadds: “As SRCC, we offer a platform in the heart of Europe for companies such as Boldyn, researchers, users and the region. Practical testing can often shorten development times and make innovations for the digitalisation of railway operations more quickly accessible to employees and customers.”

The results of the trial align seamlessly with Boldyn's strategic direction in the rail sector. As a system partner of Deutsche Bahn AG, the company is responsible for deploying private 5G networks that digitally support maintenance, logistics, and operational processes – aimed at reducing downtime, automating processes, and driving the sustainable digital transformation of rail transport.

Global market leader with strong references

Boldyn Networks is the preferred connectivity partner for customers across a wide range of industries, including transportation systems (Deutsche Bahn, London Underground, New York Subway), aviation (Helsinki Airport), maritime transport (Port of Kokkola in Finland and OPCSA (Operaciones Portuarias Canarias SA) in the Canary Islands), industry (BASF Spain) and healthcare (Oulu University Hospital, Finland). The company also supports smart city initiatives such as "Roma5G" in Rome and Sunderland in the UK, and provides connectivity for stadiums, universities, and military bases, primarily in North America.
