As the largest railway hub in Asia and an important railway gateway in the capital, Beijing Fengtai Railway Station (Fengtai Station) was officially put into operation on June 20.

Fengtai Station is the first large-scale modern railway station in China that has the facilities to operate both ordinary speed and high-speed trains. Much innovation has been adopted in the design and construction of this railway hub.

1. High-speed railway runs on top while ordinary speed on the ground

Fengtai Station has a building area of 400,000 square meters with 17 platforms and 32 rail lines.

There are 11 platforms with 20 ordinary-speed tracks on the ground floor and six elevated platforms with 12 high-speed tracks. The station can accommodate up to 14,000 passengers waiting for trains at the same time every hour.

Running high-speed railways on the top floor has stricter requirements for bearing beams. The main structure of the station is reinforced with reinforced steel, that allows components that can be pressed or pulled by hand as the main structure of the steel structure.

The maximum section size of the steel-filled concrete tube pillars supporting ordinary speed railway yard is 4.55m × 2m. Meanwhile the maximum section size of the reinforced steel beam supporting high-speed railway is 5.6m × 1.4m, spanning 21.5 meters. The construction of a single super beam requires intensive binding of 252 longitudinal steel bars and nearly 2,000 stirrups.

2. Natural light source pouring down from the roof

The station is fully illuminated by natural light during the day. The top roof is "lit" by a transparent strip, and in the waiting hall, natural light also pours down from the roof.

The design of the station uses a magic light guide technology, namely, flat panel lighting devices with double mode non-electric lighting system, which is commonly known as "light guide tube." Looking up from downstairs, it's like having electric lights on the roof.

On the floor of the high-speed terminal, the design team used a specially made light guide tube device, to channel natural light and sunlight into the waiting hall for illumination. From dawn to dusk, even on cloudy or rainy days, the light filtered into the room by the system is quite sufficient.

More than 200 light guide tubes provide natural light for the 10-meter-high waiting hall. The overall energy saving rate is expected to reach more than 10 percent with this technology, saving about 950,000 kWh of electricity every year and reducing carbon emissions of more than 900 tons.

3. Smart construction makes stations intelligent, safe and efficient

Fengtai Station also has an intelligent brain. A monitoring system based on the Beidou unified time-space benchmark, has been set up to monitor the natural environment and the condition of the structures in real time continuously, such as glass curtain walls and corroded steel components.

It also integrates passenger management, passenger service, passenger equipment, emergency commands and other services of the station with intelligent control service, data analysis and AI service, intelligent audio and video analysis, so as to realize intelligent operation and management of the station.
