盘兴高铁自沪昆高铁盘州站引出，经贵州省六盘水市盘州市石桥镇、响水镇、保田镇，进入黔西南布依 族苗族自治州兴义市清水河镇，终至兴义南站。全线新建保田、兴义南2座车站以及平菁线路所1座，改 建盘州站1座车站。 盘兴高铁建成通车后，贵阳至兴义2小时左右可达，贵阳至省内8个市(州)将形成1至2小时高铁交通圈， 对完善区域铁路网布局，促进当地经济社会发展，加强区域间互联互通具有重要意义。 新京报讯据"中国铁路"消息，9月6日7时46分，随着57201次检测车从盘州站驶出，新建盘州至兴义高速 铁路(以下简称"盘兴高铁")启动联调联试，进入工程验收关键阶段，为全线如期开通奠定了坚实基础。 盘兴高铁设计时速250公里，正线长度约98公里，其中桥梁46座，隧道38座，桥梁和隧道占比90.66%。 ...

Core Viewpoint - The successful completion of the contact network hot sliding test for the Pan-Xing High-Speed Railway marks a significant step towards the railway's commissioning and operational readiness [1][2]. Group 1: Test Completion - The hot sliding test was successfully completed on September 5, 2023, with the test train arriving at the Xinyi South Station [1]. - The contact network was energized successfully on September 5, 2023, at 0:30 AM, allowing the hot sliding test to proceed [1]. Group 2: Importance of the Test - The hot sliding test is a critical step before the joint debugging and testing of electrified railways, ensuring the stability and reliability of the power supply system [2]. - The test involved precise measurements of the contact network voltage and the relationship between the contact wire and the pantograph, confirming that the equipment meets the conditions for joint debugging and testing [2]. Group 3: Project Significance - The Pan-Xing High-Speed Railway, approximately 98 kilometers long with a design speed of 250 km/h, is the last project needed for Guizhou Province to achieve its goal of "high-speed rail connectivity for every city" [4]. - Upon completion, the railway will enable travel from Guiyang to Xinyi in 2 hours, creating a high-speed rail traffic circle within 1 to 2 hours to eight central cities in the province, significantly enhancing regional connectivity and economic development [4].
