中新网南宁8月21日电(吴炜宋斯丽)8月21日9时50分，随着检测列车从崇左南站缓缓驶出开往凭祥东 站，标志着南宁至凭祥高铁崇左至凭祥段(简称"南凭高铁崇凭段")正式启动联调联试工作，进入工程验 收关键阶段，为年内开通运营奠定基础。 图为南凭高铁崇凭段联调联试检测列车通过龙州站。李伊摄 南凭高铁崇凭段正线全长81.522公里，设计时速250公里，线路东起崇左南站，经宁明县、龙州县，终 至凭祥市凭祥东站，由广西交通投资集团投资建设、中国铁路南宁局集团有限公司(简称国铁南宁局)代 建，是中国中越边境城市的重要交通基础设施项目。 南凭高铁崇凭段联调联试期间，将以达到设计速度250公里/小时为目标，安排综合检测列车和相关检测 设备在线路上逐级提速、折返运行，采集轨道、接触网、基站等设备数据；测试道岔、桥梁、隧道等结 构的适用性；验证信号、客服信息、灾害监测等系统的兼容性和功能，逐步进行测试、调试、整改和优 化，最终实现各子系统和整体系统满足验收要求，使线路具备开通条件。 据国铁南宁局崇左现场指挥部工程师黄臣昌介绍，南凭高铁崇凭段联调联试自8月21日起至11月底，这 个阶段主要在不同速度等级下对轨道、信号、供电等系统进 ...

Core Points - The successful electrification of the Nanning-Pingxiang high-speed railway's Chongzuo-Pingxiang section marks a significant step towards the goal of opening the line within the year [1][2] - The electrification process involves converting 220 kV three-phase AC from the local power grid to 27.5 kV single-phase AC, which is essential for train operations [1] - The project is expected to reduce travel time between Nanning and Pingxiang from over 4 hours to just over 1 hour, enhancing connectivity between China and ASEAN [2] Company Involvement - The project is financed by Guangxi Transportation Investment Group and constructed by China Railway Nanning Bureau Group Co., Ltd., with the electrification work undertaken by China Railway Electrification Bureau [1] - Various units, including Guangxi Transportation Investment's Nanchong Company and Nanning Railway Engineering Construction Command, collaborated to ensure the successful electrification [1] Technical Details - The electrification process is a critical step before the line can undergo joint debugging and testing, ensuring that all systems meet safety standards [1] - Following the electrification, tests will be conducted to assess the relationship between the contact network and the pantograph under live conditions [2] - The total length of the Chongzuo-Pingxiang section is 81.522 kilometers, designed for a speed of 250 km/h [2]

Core Viewpoint - The completion of the decoration and renovation standards for the station buildings of the Nanning-Pingxiang High-Speed Railway marks the full-scale decoration phase of the project, with expectations for delivery and acceptance by June 2023, and the line is anticipated to be operational within the year [1][2]. Group 1: Project Overview - The Nanning-Pingxiang High-Speed Railway (Nanning to Pingxiang section) has a total length of 81.522 kilometers and is designed for a speed of 250 km/h, connecting several key locations and reserving conditions for future extension to Vietnam [1]. - The project includes the construction of three new stations: Ningming East Station, Longzhou Station, and Pingxiang East Station, with Pingxiang East Station being the largest [1][2]. Group 2: Construction Progress - As of now, the main structures of the three station buildings have been completed, with over 76% of the overall station construction finished and 55% of the "four electrical" works completed [2]. - The construction team is expected to peak at over 1,000 workers and 58 construction vehicles to expedite the completion of the station buildings by the end of June [2]. Group 3: Strategic Importance - Once operational, the Nanning-Pingxiang High-Speed Railway will significantly reduce travel time between Nanning and Pingxiang to just over one hour, enhancing the transportation link between China and ASEAN [2]. - The project is crucial for improving transportation infrastructure in border areas, facilitating Guangxi's integration into the "Belt and Road" initiative, and accelerating the development of the Western Land-Sea New Corridor [2].
