China, already home to the world's highest bridge, is planning to build the world’s deepest and largest high-speed railway station at the popular Badaling section of the Great Wall.

The station is expected to be completed by the end of 2019, in preparation for the Winter Olympics in 2022.

At a depth of 335 feet, the station’s underground area will span about 380,000 square feet—the size of five standard soccer fields—according to China Daily.

There will be three floors, with separate levels for passengers who are arriving and departing, connected by what will be the country’s tallest escalators at 62 feet.

The station will be part of a railway network connecting Yanqing and Chongli. Trains will reach a maximum speed of 350 kilometers per hour, He Yi of the Beijing Municipal Commission of Housing and Urban-Development told China Daily.
