Beijing-Xiong Intercity Railway is here! Take the high speed train to Xiongan
On December 27, the new Beijing-Xiong’an Intercity Railway section of Daxing-Xiongan Airport was opened for operation, the Beijing-Xiong Intercity Railway was fully connected, and Xiong’an Station was put into operation simultaneously.
The fastest travel time between Beijing West Railway Station and Xiong’an New Section is 50 minutes, and the fastest travel time between Daxing Airport and Xiong’an New Section is 19 minutes.
After the opening of the new section from Daxing Airport to Xiong’an on the Beijing-Xiong Interurban Railway, the Department of Railways will be tasked with operating 16 pairs of moving trains with a maximum operating speed of 300 kilometers per hour. Beijing-Xiong Intercity Railway extensively uses equipment based on advanced technologies such as big data, cloud computing and next-generation mobile communications to comprehensively improve the passenger experience and the operation and maintenance of high-speed trains.
Go, take the high-speed train to Xiongan and search the “City of the Future”!

China’s first highway and rail dual-use sea crossing bridge put into use
At 9:43 a.m. on December 26, with the G5322 train departing from Pingtan Station, the Fuzhou Ping (Tan) Railway was officially opened for operation, ending the history of Pingtan Island without a railway. The Pingtan Strait Expressway and the Railway Bridge, the first highway railway bridge in China, were put into use simultaneously. The fastest travel time between Fuzhou and Pingtan is 35 minutes.
The Pingtan Strait Road-Rail Bridge, one of the world’s top three air vents, is a key control project for Fuping Railway. It is the first dual-use dual-use sea crossing bridge in China, with a total length of 16.34 kilometers, of which the sea crossing section exceeds 11 kilometers. The top layer of the bridge is a six-lane two-lane highway with a design speed of 100 kilometers per hour; the lower layer is a double-track railway with a design speed of 200 kilometers per hour.
This bridge is considered a Chinese miracle created in the “restricted zone of bridge construction”. The bridge location is windy, high surf, deep water, and swelling. The geological conditions of the seabed are complicated and the effective operating time is short. In conditions without typhoons, the gusts can reach level 10 or more. Today, Chinese bridge builders have successfully overcome the “world-class nozzle” problem in bridge construction.
From then on, another dragon of steel, marching against the wind!

Yinxi high-speed railway opened to traffic, Ningxia connected to the national high-speed rail network
On December 26, the Yinchuan-Xi’an high-speed railway was put into operation. The operating time of the Yinchuan-Xi’an Railway will be reduced from 14 hours today to about 3 hours.
The Yinxi High Speed Railway connects the three provinces of Ningxia, Gansu and Shaanxi. Its openness to traffic means that Ningxia is officially connected to the national high-speed rail network, and it has built a network between the Yinchuan-centered Ningxia Yellow City group and the Xi’an-centered Guanzhong city group. The comfortable passage greatly facilitates the movement of people along the route.
In other words, the time it takes from “lonely smoke in the desert” to “seeing Chang’an flowers” is greatly shortened.
It is worth noting that the CR300 Fuxing EMU also went online on the Yinxi high-speed train on the first day of opening. The CR300 Fuxing EMU launched this time has two models, CR300AF and CR300BF, with sea and sky blue and peacock blue as the main colors, and a maximum design operating speed of 250 kilometers per hour.

“Two lines and one station” opened in Hunan, creating transport obstacles in five provinces, regions and cities
On December 26, the Hunan “Two Lines and One Station” railway project (the second line of the Yuhuai railway, the Huailiu electrical transformation of the Jiaoliu railway, the Huaihua western sorting station project) was officially opened for the operation.
This means that Hunan has opened a major passenger and freight corridor connecting the western urban agglomeration of Union Chengyu and the South China Estuary in the south. The railway transportation capacity of the border regions of Hunan, Hubei, Chongqing, Guizhou and Guangxi will be greatly increased.
After “two lines and one station” are opened and operated, the railway transportation equipment will be more advanced, the cross-interference of the traffic flow will be greatly reduced, the transportation organization will be more fluid, and the transportation capacity will be will increase by more than 4 times than before construction, which will effectively solve the rail transport bottleneck in the five provinces, urban areas and border areas, To alleviate the difficult situation of external transport capacity in the regions central and western Hunan.
The country’s first high-speed train station renovation project is fully completed
Recently, the first renovation project of the national high-speed rail central station was fully completed. After the renovation of Shenzhen North Station, Guangzhou-Shenzhen-Hong Kong high-speed rail, Xiamen-Shenzhen high-speed rail and Ganshen high-speed rail under construction will be widely upgraded.
The Shenzhen North Railway Station Renovation Project is reported to be the first time the “dilapidated and expanded” method of demolishing and rebuilding part of the roads and platforms has been adopted on the condition that the station does not stop operating. and the existing scale does not change. This is the first time in China.
The renovated Shenzhen North Railway Station is capable of connecting lines in Ganzhou, Maoming and Xili. With the introduction of more new lines in the future, the total number of trains receiving and dispatching from Shenzhen North Station will reach 413 pairs at most, which can better meet the travel needs of passengers.

“West to East Power Transmission” projects are completed and put into production
State Grid Sichuan Electric Power Company revealed on December 27 that the Sichuan section of the Yazhong-Jiangxi ± 800 kV UHV DC transmission project with a total length of 206 kilometers was completed. This is the first province of the five provinces along the project to achieve the connection of the line.
Yazhong-Jiangxi ± 800 kV DC UHV Transmission Project is a major power transmission project responding to the national energy strategy of “west to east power transmission”, ensuring clean energy consumption in the west and meets the ecological development of the central and eastern regions. It is the fourth project of Sichuan UHV Transmission Lines. The project starts at the Yanyuan converter station in Sichuan and ends at the Nanchang converter station in Jiangxi, passing through the 5 provinces of Sichuan, Yunnan, Guizhou, Hunan and Jiangxi. The total length of the line is 1,711 kilometers and the total investment of the project is approximately 24.4 billion yuan.
In addition, the Kunliulong DC project, invested in and built by China Southern Power Grid Corporation, was fully commissioned on December 27 (full-load, three-terminal operation). This is the world’s first flexible UHV DC transmission project, creating the world’s number one power technology in 19 projects. One. The project is estimated to transmit 33 billion kWh of electricity per year, which is equivalent to the electricity consumption of the entire society in Hainan province in one year.
The Kunliulong DC project is a key project for the transmission of energy from the west to the east of the country. After its completion and commissioning, the South China power grid will account for more than 54% of non-fossil energy, increasing the power transmission capacity of China West-East Power Transmission Channel by 16 %.
