How China Built the World’s Biggest Train Station on Top of a Mountain

How did China build the world's largest train station — on top of a mountain — in just 38 months? And how do you install a 16,500-tonne curved steel roof with no walls to build from? Welcome to Chongqing East Station: China's $7.8 billion high-speed rail megaproject. 1.22 million square metres. 40,000 peak workers. A 16,500-tonne steel tube truss roof assembled on the ground and hydraulically slid 57 metres upward onto 41-metre tree-shaped "Huangjue" columns. This is the complete engineering story. In this documentary: • How 40,000 workers built a 1.22M m² station in just 38 months on a mountain • The sliding assembly method — why the 16,500-tonne roof was built on the ground first • The Huangjue tree columns — 41-metre branching steel structures designed for earthquake resistance • Stainless steel cladding installation at 57 metres above a mountain slope • Why Chongqing East Station is now the largest railway hub in the world • The high-speed rail network connecting Southwest China to 14 major cities 🔔 Subscribe for weekly engineering megaproject documentaries. #ChongqingEast #Megaprojects #HowItsMade #BulletTrain #FactoryTour #Engineering #Documentary #Construction #Railway #InsideTheFactory #CivilEngineering #FullProcess #Trending ⚠️ IMPORTANT: ABOUT THIS VIDEO ------------------------------------------------------------------- This is an educational documentary analyzing the engineering and construction of public infrastructure, based entirely on open-source information.
