An important component of the Beijing-Harbin-Beijing-Hong Kong-Macao Corridor: the entire beam erection project of the Hai-Hai high-speed railway was successfully completed

According to news on November 11, recently, the beam erection project of the Tieli to Yichun section of my country's northernmost high-speed railway, Haiyi High-speed Railway, has been fully completed, laying a solid foundation for the smooth track laying of the line. This project is an important extension of the Beijing-Harbin-Beijing-Hong Kong-Macao corridor of my country's "Eight Vertical and Eight Horizontal" high-speed rail network. It is also the first railway line under construction in my country with the highest mid-latitude, the largest temperature difference throughout the year in the area where the entire line is located, and the first to pass through multi-year island permafrost. District’s high-speed railway.

The Hai-Yi High-Speed ​​Railway in Harbin City, Heilongjiang Province passes through Suihua City and finally reaches Yichun City. The entire journey is 318 kilometers long and has a design speed of 250 kilometers per hour. There are 9 stations along the line, including Harbin, Harbin North, Hulan North, Xinglong Town West, Suihua South, Qing'an South, Tieli, Riyuexia and Yichun West

According to my understanding, the Harbin-Yi high-speed railway includes the section from Harbin to Tieli and the section from Tieli to Yichun. Among them, the construction of the Tieli to Yichun section started in October 2021, and the bridge construction began in July 2022. After the entire line of the Haiyi High-speed Railway is completed and opened to traffic, the railway travel time from Harbin to Yichun will be greatly shortened, further strengthening the connection between the Northeastern region and the eastern coastal areas, Beijing-Tianjin-Hebei and other developed regions, and is of great significance for realizing resource sharing and complementary advantages of cities along the line.
