en.Wedoany.com Reported - Recently, after 320 minutes of overnight efforts by construction workers, the insertion and laying of a crossover turnout at the Anqing end of Track 8 at Ma'anshan East Station for the newly built Chaohu to Ma'anshan High-Speed Railway (hereinafter referred to as the "Chaoma High-Speed Railway") was successfully completed. This marks the successful connection of the Chaoma High-Speed Railway with the existing Ning'an High-Speed Railway at Ma'anshan East Station, laying a solid foundation for subsequent system-wide commissioning and trial operations, as well as the line's official opening.
Ma'anshan East Station serves as a shared station for the under-construction Chaoma High-Speed Railway and the existing Ning'an High-Speed Railway. This construction involved multiple stages, including the modification of existing equipment, removal of old tracks, overall lateral movement of the crossover turnout, and precise connection of new and old tracks. All work had to be completed during the nighttime "maintenance window" of the existing line, presenting challenges due to overlapping specialties and complex organization. The overall lateral movement of the crossover turnout, measuring 93.184 meters in length and 7.4 meters in width, posed the greatest challenge, akin to performing a high-precision "track heart transplant surgery," with construction accuracy required to be within 2 millimeters.
To ensure the smooth completion of the construction, the project's construction agent, Ning'an Railway Company, collaborated with participating units such as China Tiesiju Civil Engineering Group to optimize the plan, mobilizing over 200 construction workers and multiple pieces of machinery to tackle the task. Advanced equipment such as real-time dynamic measurement systems, total stations, and laser measuring instruments were used on-site. Ten core monitoring points were set up along the existing line, keeping deviations in key indicators such as the geometric dimensions of the turnout frame within 1 millimeter, achieving precise positioning of the crossover turnout and meeting standards for track formation in a single attempt.
The Chaoma High-Speed Railway starts from Chaohu East Station and ends at Ma'anshan East Station, with a newly built main line of approximately 61 kilometers. It includes five stations: Chaohu East, Hanshan, Zhengpugang, Ma'anshan South, and Ma'anshan East. This line is a direct high-speed railway between Hefei and Ma'anshan, expected to be ready for operation by September this year. Once completed, it will create a fast new corridor along both sides of the Yangtze River, further narrowing the spatial and temporal distance between the Hefei Metropolitan Circle and the Nanjing Metropolitan Circle. This is of great significance for improving the regional railway network layout, building a "rail-based Yangtze River Delta," and supporting the integrated development of the Yangtze River Delta and the Yangtze River Economic Belt.
