In early July 2026, China completed construction of the world’s largest train station in Chongqing, underscoring its drive to expand domestic rail capacity. By the end of the that month, the country achieved another milestone when the 15.4‑metre‑diameter Linghang shield tunnelling machine finished an 11.3 km underwater drive beneath the Yangtze River. River, setting a global record for the longest uninterrupted tunnelling by a shield machine of this size. The record‑breaking tunnel, part of the Chongtai Yangtze River Tunnel, will link Tunnel linking Shanghai’s Chongming Island with Taicang in Jiangsu, allowing will accommodate 350 km/h trains trains, cutting the island‑to‑Shanghai travel time to cross about 17 minutes, with the river in about segment taking roughly two minutes. Together, these projects highlight China’s rapid rollout The 4,000‑tonne machine operated at a depth of high‑speed rail infrastructure 89 m, with alignment tolerances controlled to the millimetre and its use of advanced engineering technologies the structure designed to enhance national connectivity. withstand water pressure up to 0.9 MPa. Project officials, including deputy manager Wang Yi, highlighted the precision required for safety and passenger comfort. Completion of the tunnel is slated for the end of 2024, after which Chongming Island will receive its first high‑speed rail connection.
