Core Points - The Xi'an to Yan'an high-speed railway has officially entered the joint debugging and testing phase, marking a significant step towards its operational launch [1] - The joint debugging and testing phase is crucial for verifying and optimizing the compatibility of various systems, including track, power supply, and signaling, ensuring technical reliability for the railway's opening [1][3] Infrastructure Details - The Xi'an to Yan'an high-speed railway spans a total length of 299.8 kilometers, designed as a double-track high-speed railway with a maximum speed of 350 kilometers per hour [5] - The railway features 47 tunnels and 67 major and medium bridges, with the bridge-tunnel ratio accounting for 91% of the newly constructed line length [3] Strategic Importance - Once operational, the railway will enhance Shaanxi's geographical advantages and its position within the national railway network, contributing to the optimization of the high-speed railway layout in China [5] - The project is expected to support rural revitalization in revolutionary old areas and facilitate the new pattern of western development [5]

Core Viewpoint - The Nanning-Pingxiang High-Speed Railway's Chongzuo to Pingxiang section has officially commenced joint debugging and testing, marking a critical phase for engineering acceptance and paving the way for its operational launch within the year [1][3]. Group 1: Project Overview - The Chongzuo to Pingxiang section of the Nanning-Pingxiang High-Speed Railway spans 81.522 kilometers with a designed speed of 250 kilometers per hour, connecting Chongzuo South Station to Pingxiang East Station [3][4]. - The project is funded by Guangxi Transportation Investment Group and constructed by China Railway Nanning Bureau Group Co., Ltd., serving as a vital transportation infrastructure project for the China-Vietnam border cities [3][4]. Group 2: Testing and Optimization - The joint debugging and testing phase will run from August 21 to the end of November, focusing on rigorous testing and optimization of track, signal, and power supply systems to ensure compliance with design speed and safety standards [4][5]. - During this phase, comprehensive data will be collected on various systems, including tracks, contact networks, and bridges, to validate compatibility and functionality [4][5]. Group 3: Impact and Significance - Once completed, the Nanning-Pingxiang High-Speed Railway will significantly reduce travel time between Nanning and Pingxiang from over 4 hours to just over 1 hour, enhancing connectivity between China and ASEAN [5]. - The project is expected to improve border transportation infrastructure and elevate Guangxi's connectivity with Southeast Asia [5].
