[Shenjiang No. 1 participated in the construction of the deepest submarine tunnel] On August 23, China's self-developed subsea tunnel shield machine rolled off the assembly line in Changsha, Hunan. The equipment shield machine has an excavation diameter of 13.42 meters, a total length of 130 meters, and a total weight of 3,800 tons. It will participate in the construction of China's deepest submarine tunnel-the Zhujiangkou Tunnel of the Shenzhen-Jiangmen Railway. The Pearl River Mouth Tunnel is a key control project of the Deep River Railway. "Shenjiang No. 1" crosses the section with a total length of 3590 meters.

• [The construction of the Jiatong Railway mainline has come to a successful conclusion]
• On July 25, 2026, the Tongjiang Extra Large Bridge of Heilongjiang Jiatong Railway completed all beam erection work, and the main project was successfully completed, marking the end of the construction of the main line of Jiatong Railway. The bridge has a total length of over 10 kilometers and is the longest newly-built bridge in the China Europe East Passage port section. As the core control project of the entire line, the bridge will greatly enhance the traffic capacity of Tongjiang Port and increase the freight capacity by more than three times after it is put into operation. The project adopts a bridge instead of road scheme to adapt to frozen soil environment, save black soil resources, and assist in the transportation of bulk commodities for foreign trade at the port.Editor/Gong Ziwei
