Core Viewpoint - The Guangzhou-Zhanjiang High-Speed Railway has officially opened, significantly reducing travel time between the North Bay Urban Agglomeration and the Guangdong-Hong Kong-Macao Greater Bay Area, thus supporting high-quality regional economic and social development [1][11]. Group 1: Railway Details - The Guangzhou-Zhanjiang High-Speed Railway connects multiple cities including Guangzhou, Foshan, Zhaoqing, Yunfu, Yangjiang, Maoming, and Zhanjiang, with a total length of 401 kilometers and a design speed of 350 kilometers per hour [3][5]. - The railway has opened seven stations: Xinxing South, Yangchun East, Yangjiang North, Mata, Maoming South, Wuchuan, and Zhanjiang North, with connections to Guangzhou Baiyun Station and Zhanjiang North Station [3][5]. Group 2: Operational Capacity - The railway will operate at a maximum speed of 350 kilometers per hour, with up to 64 train services running daily. Travel times from Guangzhou Baiyun to Zhanjiang North and Maoming South are reduced to 1 hour and 32 minutes and 1 hour and 20 minutes, respectively, cutting the previous travel time by 61 minutes [5][11]. - A flexible and differentiated pricing mechanism will be implemented to meet various passenger needs, with specific ticket prices available through the railway's official platform [5]. Group 3: Supporting Infrastructure - The Zhanjiang North Train Operation Depot, a key supporting project for the high-speed railway, is located approximately 2.3 kilometers from Zhanjiang North Station and is crucial for the maintenance and operation of high-speed trains [9][11]. - The depot includes facilities for inspecting and maintaining up to 12 standard high-speed trains simultaneously, with a maximum capacity for daily maintenance of 36 trains [9]. Group 4: Regional Impact - The opening of the Guangzhou-Zhanjiang High-Speed Railway will greatly shorten the travel distance between the North Bay Urban Agglomeration and the Guangdong-Hong Kong-Macao Greater Bay Area, facilitating travel for local residents and enhancing regional connectivity [11]. - This development is expected to improve the regional railway network layout, promote the economic and social development of the area, and contribute to building a vibrant and internationally competitive first-class bay area and world-class urban agglomeration [11].

Core Viewpoint - The successful installation of a 626-ton steel beam marks a significant milestone in the construction of the Hangzhou Bay Cross-Sea Railway Bridge, which is a key project for the Nantong to Ningbo High-Speed Railway [1] Group 1: Project Overview - The Hangzhou Bay Cross-Sea Railway Bridge is a critical component of the Nantong to Ningbo High-Speed Railway, featuring three navigation bridges and a total length of 29.2 kilometers [1] - The bridge is designed for a speed of 350 kilometers per hour and is currently the longest and highest-standard cross-sea high-speed railway bridge under construction globally [1] Group 2: Technical Details - The North Navigation Bridge is a 450-meter main span steel box-steel truss cable-stayed bridge, with two main towers (No. 8 and No. 9) and a total length of 932.7 meters, making it the largest span ballastless track cable-stayed bridge under construction in the world [1] - The design and construction challenges of this bridge are relatively rare among similar types of bridges in China [1] Group 3: Safety Measures - The Jiaxing Maritime Bureau has established a "data + precision + drill" comprehensive guarantee mechanism to ensure construction safety, including precise work window predictions and tailored simulation lifts for each beam [1] - The use of VTS, drones, and patrol boats provides full-scale control during the lifting process [1] Group 4: Future Impact - The Hangzhou Bay Cross-Sea Railway Bridge is expected to be completed and operational by 2027, ending the lack of railway access in Haiyan, Zhejiang, and significantly reducing travel time between cities in the Yangtze River Delta [1] - This project will contribute to the establishment of a "one-hour traffic circle" and further promote regional collaborative development [1]
