China has completed the construction of the Chongqing East Railway Station in just 38 months with the help of robot army on the top of a mountain, a project being described as the world’s largest high-speed railway station by area.
Located in Chongqing in southwest China, the mega station spans around 1.2–1.22 million square metres and has been developed as a major high-speed rail hub. The project cost is estimated at around $7.8 billion, according to reports shared on social platforms and media updates.

Built on a mountain, not flat land
One of the most remarkable aspects of the project is its location. The station was built on mountainous terrain, requiring engineers to first cut, level and reshape an entire mountain before construction could begin.
According to reports and visual updates shared online, the terrain was mapped in 3D before excavation. Controlled blasting was also used to remove sections of rock, while extensive groundwork prepared the site for construction.
