"CCCC Yutie No. 7" successfully launched

　　Chongqing Rail Transit Line 15 is an urban rail express line featuring "large diameter and high speed." The Phase II Section 13 project starts at University City South Station and ends at University City North First Road Station, with a total section length of 3.203 kilometers.

　　Once the entire Chongqing Rail Transit Line 15 is completed, it will connect three major transportation hubs—the Science City railway hub, Jiangbei Airport, and the Fusheng high-speed railway station—and will be an important component in advancing the construction of the Chengdu-Chongqing economic circle and accelerating the development of Chongqing's "one-hour economic circle."
