With the continuous growth of China Europe trade, the improvement of transportation capacity and efficiency of China Europe freight trains, as an important logistics channel connecting China and Europe, is particularly important. In this context, the renovation project of the Binsui Railway section of the East Passage of the China Europe freight train has emerged. The construction of this project aims to improve the transportation capacity of the Binsui Railway, optimize the operating environment of China Europe freight trains, and further promote the prosperity and development of trade between China, Russia, and China Europe.

The Binsui Railway starts from Harbin and ends at the border city of Suifenhe between China and Russia, with a history of 100 years. Suifenhe City is located in the central area of the Northeast Asian Economic Circle, and is the largest railway transportation channel between Heilongjiang Province and Russia. It is also an important port of passage for the China Europe freight train East Passage. The Suifenhe to Guojing Line project of the Binsui Railway renovated this time is located in the eastern section of the Binsui Railway in Suifenhe City. Due to the large operating slope and small curve radius, the existing line has a train speed of only 55 kilometers per hour. After the renovation, the designed speed of the line will be increased to 120 kilometers per hour, and the passing capacity of the line will be more than doubled. The renovated Binsui Railway will effectively solve the bottleneck of transportation capacity, improve the transportation efficiency of China Europe freight trains, and further promote the prosperous development of China Russia and China Europe trade.

The renovation project of the Suifenhe Guojing Line of the Binsui Railway is located in a severely cold region of China, with an effective construction period of only 7 months. Multiple seasonal frozen soil areas are distributed along the route, with a maximum freezing depth of 2.29 meters, making construction difficult. Some sections of the mountain slope are steep, making it difficult to build access roads, and the construction conditions are difficult.

China Railway Harbin Bureau Group Co., Ltd. organized the project design unit, China Railway Fifth Survey and Design Institute Group Co., Ltd., to carry out targeted local line changes and take measures such as building new bridges and tunnels to ensure the timely progress of the project. The construction unit China Railway Sixth Bureau Group Co., Ltd. optimizes the construction plan and adopts new technologies such as concrete wet spraying robotic arm, secondary lining intelligent trolley, and hydraulic inverted arch bridge to ensure construction quality during tunnel construction. Introducing IoT technology, utilizing high-precision sensors, 5G, big data, and artificial intelligence to carry out smart tunnel construction, in order to improve project construction management efficiency.

The renovation project of the Suifenhe to Guojing Line of the Binsui Railway is expected to be completed by the end of 2025. At that time, the transportation capacity of the Binsui Railway will be greatly improved, providing a more efficient and convenient transportation environment for China Europe freight trains. Meet the demand for the operation of China Europe freight trains at Suifenhe, Manzhouli, and Tongjiang railway ports, and promote the prosperous development of trade between China, Russia, and China Europe. Strengthen the level of road network, enhance the transportation capacity of Heilongjiang region, and promote regional economic development. It is of great significance for Heilongjiang to build a new highland of opening up to the north and serve the development of China Europe freight trains towards higher quality, better efficiency, and safer directions.
