In just 38 months, China finished building Chongqing East Railway Station, which is regarded as the largest high-speed railway station in the world by area.
The station, which is situated in Chongqing, southwest China, is anticipated to develop into a significant high-speed train transportation hub. It includes 15 train tracks, 29 platforms, and an area of over 1.2 million square meters.
During peak hours, the station can accommodate up to 16,000 passengers per hour. According to Xinhua, the station boasts a multi-level layout with up to eight stories.
The fact that the station was constructed on a mountain rather than level ground adds even more significance to the undertaking. Before construction could start, engineers had to level and chop a whole mountain.

While crews spent months prepping the terrain, controlled explosions were used to remove portions of the mountain.
To expedite the station's construction, the engineers employed cutting-edge robots and artificial intelligence. According to reports, concrete floors were levelled with incredibly high accuracy using laser-guided screed robots.
Heavy glass panels weighing up to 800 kg were lifted and placed by specialised glass installation robots. In addition to increasing installation speed threefold and lowering accident risks by almost 90%, the robots assisted workers in installing the glass more precisely and safely.

Robots that could move in various directions were utilised for welding, while patrol robots kept an eye on the work site around-the-clock.
These four-wheeled robots reduced labour expenses by about 40% while performing tasks almost three times faster than people thanks to technology like LiDAR, artificial intelligence (AI), and 5G.
The station required about 366,000 tonnes of steel and roughly two million cubic meters of concrete. The South China Morning Post (SCMP) estimates that the project involved about 40,000 workers.
Engineers built the 16,500-ton steel roof at ground level rather than building it high above the earth. Using hydraulic technology, the complete structure was then gradually raised and moved 57 meters upward into position."Huangjue" columns, which are enormous steel columns shaped like trees, support the roof. These branching structures, which are roughly 41 meters high, were created specifically to make the station earthquake-resistant. On the steep slope, workers also put stainless steel cladding at heights of over 57 meters.
According to sources, some of the station's trains are longer than the height of the Eiffel Tower, and each platform is more than 400 meters long.
The station links southwest China with 14 important cities, including Chengdu, Zhangjiajie, Changsha, Wuhan, Xi'an, Kunming, Beijing, Shanghai, and Guangzhou. It is a part of China's extensive high-speed rail network.
