Core Viewpoint - The extension of Line 5 in Shenzhen is set to enhance transportation efficiency in the southern region, creating a significant transit artery of approximately 50.526 kilometers with 37 stations, expected to open within the year [1][2]. Group 1 - The Line 5 west extension project has achieved dual power supply (35KV and 400V), ensuring stable electricity for equipment and necessary power for testing and debugging [1][2]. - The project spans 2.88 kilometers, starting from Huangbeiling Station and ending at the Grand Theater Station, with three new stations: Dongmen Road Station, Jianshe Road Station, and Grand Theater Station [1][2]. - The extension will allow direct access to the Grand Theater Station from Line 5 without needing to transfer to Line 2, significantly improving convenience for commuters [2]. Group 2 - The construction faced challenges due to dense urban infrastructure and complex underground networks, including the need to tunnel under existing structures like the Guangzhou-Shenzhen Railway [2]. - The successful completion of the dual power supply marks a critical milestone in the project, providing essential power for the operational readiness of the line [2].
