The Northeast Railway Network, with Harbin-Dalian High-speed Railway as its north-south spindle, has been integrated into China's high-speed railway network by connecting with Qin-Shenzhen passengers and forming Shenyang-Changchun high-speed railway network. The two-hour economic circle centered on cities such as Dalian and other cities, and the four-to-six-hour economic circle from major cities to Beijing, have injected vitality into the revitalization and development of Northeast China.
