Core Viewpoint - The Panxun High-Speed Railway (盘兴高铁) has entered a critical phase of engineering acceptance with the commencement of joint debugging and testing, laying a solid foundation for its timely opening [1] Group 1: Project Overview - The Panxun High-Speed Railway is designed for a speed of 250 km/h and has a total length of approximately 98 kilometers, with 46 bridges and 38 tunnels, making up 90.66% of the route [1] - The railway starts from the Panzhou Station on the Hukun High-Speed Railway and passes through various towns in Liupanshui City and ends at Xinyi South Station in the Qiannan Buyi and Miao Autonomous Prefecture [1] Group 2: Economic and Social Impact - Once operational, the railway will reduce travel time from Guiyang to Xinyi to about 2 hours, creating a high-speed rail traffic circle within 1 to 2 hours for 8 cities (prefectures) in the province [1] - The completion of the Panxun High-Speed Railway is expected to enhance the regional railway network layout, promote local economic and social development, and strengthen inter-regional connectivity [1]

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].
