In the early hours of September 10, Keqiao Railway Station on the Zhejiang Shaoxing Intercity Railway completed the replacement of a railway bridge weighing over 4,000 tons. The bridge replacement was carried out during the five-hour early-morning train suspension window and, for the first time, used artificial intelligence technology to achieve millimeter-level precise placement. The project replaced the original two-track bridge with a four-track bridge, providing a new solution for the upgrading and renovation of existing railways in China.
