Core Viewpoint - The Chengdu Metro Line 30 Phase I has officially been unveiled, enhancing the transportation network in southern Chengdu and featuring advanced technology and futuristic station designs [1][3]. Group 1: Project Overview - The metro line spans four administrative districts in Chengdu, connecting the eastern terminal at Longquanyi South Railway Station to the western terminal at the second terminal of Shuangliu Airport [3]. - It fills a service gap of approximately 3 kilometers between existing lines 7 and 9, thereby increasing the density of the regional rail network [3]. - The line includes six transfer stations, connecting with seven existing lines, and facilitates seamless transfers between metro, airport, and railway services [3]. Group 2: Design and Technology - The design theme of the stations is "modern fashion and sci-fi creativity," creating an aesthetic space that connects the present with the future [4]. - The line is the first in the country to utilize "conventional full automation + train-to-train communication" technology, allowing trains to interact in real-time without relying on ground control [4]. Group 3: Construction Challenges - The construction faced significant challenges, including multiple crossings of important infrastructure, with the project requiring precision control within millimeter levels [5]. - The construction team implemented an innovative four-layer protection system to ensure the stability and safety of the tunnels during the complex construction process [5]. Group 4: Future Impact - The opening of Line 30 is expected to optimize the urban spatial layout of Chengdu and provide citizens with a more intelligent, efficient, and safe travel experience [7].
