A team of researchers from China Railway Chengdu Group, the China Academy of Railway Sciences, and China Railway Container Transport Corporation (CRCT) has developed a new satellite-linked positioning device aimed at enhancing the protection and tracking of containers on the China-Europe Railway Express. The device leverages China’s BeiDou Navigation Satellite System, a domestic alternative to the U.S. GPS and the EU’s Galileo, to provide real-time location monitoring and data collection for rail containers.

The development comes amid ongoing efforts to address longstanding logistical challenges inherent in transcontinental rail freight, particularly on the vital China-Europe route, a cornerstone of China’s Belt and Road Initiative. The railway, connecting more than 200 cities across 26 European countries and 11 Asian countries, serves as a faster alternative to sea shipping for Chinese exports, running primarily along three major corridors through Kazakhstan, Mongolia, Russia, Belarus, and Poland.

Testing of the novel mountable tracking device covered both domestic and international sections of the China Railway Express, focusing on transmission integrity, battery life, and satellite lock times. Researchers reported successful all-weather, accurate perception of container status based on the autonomous and controllable features of BeiDou-3, China’s latest generation satellite navigation system. According to their study, published in April, the technology offers enhanced technical support for container asset management, transport safety, logistics, and operational control.

Current logistics operations still rely heavily on intermittent, station-to-station tracking, which creates blind spots when containers leave railway sections. The new device aims to provide continuous, real-time visibility of shipping containers, including sensitive data points such as door open/close status, temperature, and acceleration, potentially improving security and risk management throughout the journey. Future research will seek to develop an intelligent management system featuring real-time monitoring, anomaly alerts, and predictive risk analytics.

The improvement in container tracking dovetails with the wider integration of BeiDou systems into China’s railway infrastructure. Approximately 74% of the national railway network’s positioning and timing equipment now employs a combination of BeiDou and GPS technology, with BeiDou increasingly dominant. The Chongqing-Duisburg freight corridor, in particular, employs BeiDou satellite positioning alongside 5G communications to monitor safety and location data, while the digital China-Europe goods train platform at the Xian International Port utilises BeiDou for container condition monitoring, including environmental factors like temperature and humidity.

China is actively upgrading the BeiDou-3 system through satellite replacements and orbital realignments aimed at improving global coverage. Developers stress the importance of harnessing BeiDou-3’s capabilities to design scalable and practical container tracking solutions suitable for diverse container types.

CRCT, which manages a network of railway container terminals across China and maintains subsidiaries and partnerships in Germany, Kazakhstan, Russia, Belarus, Lithuania, Poland, and Mongolia, serves as an international platform supporting the China-Europe rail service. Its role highlights the strategic importance of enhanced digital monitoring solutions in facilitating secure and efficient cross-border freight transport along the Belt and Road corridor.
