Beijing’s Mega Underground Transportation Hub Main Structure Finished

News Desk

Beijing: The main structure of Asia’s largest underground transportation hub at Beijing Sub-centre Station in Tongzhou District has been completed on Friday. It is expected to be operational by the end of 2025.

The hub is designed to integrate multiple transportation systems, including two intercity railways, one national railway, five urban rail transit lines, one suburban railway, and 15 bus lines.

The ground level of the hub, known as the ‘city living room’, will feature over 1.3 million square meters of office and commercial space, hotels, and residences. Urban sunlight will illuminate the underground area, enhancing its integration with the city.

The roof design incorporates energy-saving technology, improving thermal insulation, stability, and durability. This technology can reduce cooling electricity usage by an amount equivalent to the energy consumed by about 3,200 household air conditioners each summer.

International and domestic designers studied existing transit-oriented development (TOD) examples, like China’s Shanghai Hongqiao Integrated Hub and Hong Kong West Kowloon Station, and La Défense Station in France, when drawing up plans for the Beijing project.

The three-layer underground station integrates the station and the city proper. People on the ground level won’t realize there’s a transportation hub below.

Among the special features is a design to bring natural light to the platforms on the third underground floor. Passengers waiting on the second underground floor will be able to look down to see whether the trains they are waiting for have arrived below.

A second special feature is the ease of traffic transfer. The transfer distance between two underground lines is nearly zero. Over 450,000 people a day will transit in the huge hub, which will connect three subway and two high-speed train lines and provide airport links.
