On January 16, 2025, at Yangjiang North Station, the first pair of 500 - meter - long steel rails were accurately positioned into the slots. This crucial move officially kicked off the long - rail laying work of the Guangzhou - Zhanjiang High - Speed Railway, marking a significant leap in the construction of the Guangzhou - Zhanjiang High - Speed Railway and laying a solid foundation for the smooth completion and opening of the project by the end of 2025.
The track - laying project of the Guangzhou - Zhanjiang High - Speed Railway is massive and meticulous. For the main line, the ballastless track is 739.431 track - laying kilometers long, the ballasted track is 10.791 track - laying kilometers long, 59.9 kilometers of station - line track - laying need to be completed. Meanwhile, 212 new turnouts need to be laid, and the amount of ballast used reaches 221,000 cubic meters.
During the construction process, difficulties came one after another. Tight construction schedules, large management spans, and frequent cross - construction operations were all "stumbling blocks" in front of the builders. To promote the track - laying operation with high quality and high efficiency, the participating construction units activated domestically leading adjacent - line track - laying equipment. This advanced equipment has powerful functions and can lay steel rails on both the main line and adjacent lines simultaneously. Compared with traditional track - laying machines, the operation efficiency is directly increased by 50%, and it is expected that the maximum daily long - rail laying record can reach 9 kilometers.
As a key component of the national "Eight Vertical and Eight Horizontal" high - speed railway network and the 350 - km/h coastal railway passenger transportation corridor, the Guangzhou - Zhanjiang Railway is of great strategic significance.
