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

As a retired civil construction Engineer participated on DESIGN for STEEL and CONCRETE works as well as SURVEY and SUPERVISION in Austria Germany Australia and New Guinea Highlands, but this MONUMENTAL ENGINEERING CONSTRUCTION WORK is more than EXTRAORDINARY for any DETAIL and TIMESCALE of ACHIEVEMENT and gives me INCENTIVE to PARTICIPATE at my 85.thanks for your GREAT REPORT it is just BEAUTIFULL. TO SEE THAT CREATED.

Building a 1.22 million square meter station in just 38 months is mind-blowing. The logistics of lifting a 16,500-tonne steel roof on a mountain peak is next-level engineering. Incredible look at Chongqing East!

This isn't just a station; it’s a vertical city integrated into a high-speed rail spine. The use of ballastless slab tracks bolted directly to the concrete floor ensures stability at 350 km/h—technology the U.S. rail system is still decades away from implementing at scale. Integrating eight layers of transit, from sub-surface metro tunnels to elevated retail concourses, requires a level of multimodal planning and structural load distribution that remains the gold standard of the 21st century.

NO WARS. ONLY DEVELOPMENT .

This isn’t just a train station… it’s a modern architectural masterpiece. The scale, the engineering, the tree-like steel columns, the roof floating above a mountain — everything feels like humanity refusing to accept limits. Chongqing honestly looks like the future of urban civilization.

The aerial views made this station look unreal. So massive and beautiful.

This is why China is in 2050 and us we are still interfering in other countries while other countries are working for technologies , progresses here we even not have a bullet train😢 😢

China tamed Nature's stubborn landscape since the Ancient Great Wall to serve for the greater good of Chinese intelligence.

The US does not need to be worried about war with China. China has already outdone The US and the World hands down with the projects they have been building and making work brilliantly. Congratulations China.

Wonders of the world created by great Chinese who never stopped inventing and building things very useful for their citizens. As always, we have a lot to learn from them. Thank you very much for sharing.

American should stop saying China is stealing their technology. There is no example in American like this, even in their dream.

“Station first, city follows.” That line perfectly captures modern China’s approach to infrastructure. Incredible documentary — the pacing, visuals, and narration made a construction project feel cinematic.

Yes thank you I love it beside my present hobby of computer integrated artwork ,worked decades with CHINESE ENGINEERS in AUSTRALIA FOR COAL POWER STATIONS all nice boys we should appreciate each other more to stabilize the WORLDS GEOPOLTICAL SITUATION simply work together for a sustainable FUTURE TOGETER. not forcefully outbid each other. Hope not to late some power POLITITIONS will appreciate it believe CHINAS POLITICAL PHILOSOPHY IS EXISTENTIAL TOWARDS IT.
