China’s first road-rail dual-use sea-crossing bridge was put into use

At 9:43 on December 26, with the G5322 train leaving Pingtan Station, the Fuzhou-Ping (Tan) Railway was officially opened for operation, ending the history of Pingtan Island’s no railway. The Pingtan Strait Highway and Rail Bridge, China’s first road-rail bridge, was put into use simultaneously, and the fastest travel time between Fuzhou and Pingtan is 35 minutes.

The Pingtan Strait Road-Rail Bridge, one of the world’s three major vents, is a key control project for the Fuping Railway. It is China’s first road-rail dual-use sea-crossing bridge with a total length of 16.34 kilometers, of which the sea-crossing section exceeds 11 kilometers. The upper layer of the bridge is a two-way six-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 regarded as a Chinese miracle created in the “bridge construction restricted zone”. The location of the bridge is windy, high waves, high, deep and swelling, and the seabed geological conditions are complex, and the effective operation time is short. In non-typhoon conditions, gusts may reach level 10 or above. Today, Chinese bridge builders have successfully overcome the problem of “world-class tuyere” in building bridges.

From then on, another steel dragon, marching against the wind!

Yinxi High-speed Rail opened to traffic, Ningxia connected to the national high-speed rail network

On December 26, the Yinchuan-Xi’an high-speed railway opened for operation, and the operating time of the Yinchuan-Xi’an railway will be shortened from the current 14 hours to about 3 hours.

The Yinxi High-speed Railway connects the three provinces of Ningxia, Gansu and Shaanxi. Its opening to traffic signifies that Ningxia has officially connected to the national high-speed rail network. It has built a network between Ningxia along the Yellow River with Yinchuan as the center and Guanzhong urban agglomeration with Xi’an as the center. The convenient passageway greatly facilitates the travel of people along the route.

In other words, the time taken from “Lone Smoke in the Desert” to “Seeing Chang’an Flowers” is much shorter.

It is worth noting that the CR300 Fuxing EMU was also put into operation on the Yinxi High Speed ​​Rail 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 design maximum operating speed of 250 kilometers per hour.

Hunan “Two Lines and One Station” opened, opening up transportation bottlenecks in five provinces, regions and cities

On December 26, the Hunan “Two Lines One Station” railway project (the second line of Yuhuai Railway, Huai Liu electrification transformation of Jiaoliu Railway, Huaihua West Marshalling Station project) was officially opened for operation.

This signifies that Hunan has opened up a major passenger and freight channel from the west to the Chengdu-Chongqing urban agglomeration and the south to the South China estuary. The railway capacity of the border regions of Hunan, Hubei, Chongqing, Guizhou and Guangxi will be greatly increased.

After the “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 smoother, and the transportation capacity will be increased by more than 4 times compared with the previous construction. , To alleviate the tension of external transportation capacity in central and western parts of Hunan.

The country’s first high-speed rail hub station renovation project is fully completed

Recently, the first domestic high-speed rail hub station renovation project has been fully completed-after the renovation of Shenzhen North Station, the Guangzhou-Shenzhen-Hong Kong high-speed rail, Xiamen-Shenzhen high-speed rail and the Ganshen high-speed rail under construction will be comprehensively improved.

It is reported that the Shenzhen North Railway Station renovation project is the first time in China that the “dilapidated and expanded” method has been adopted to demolish and rebuild part of the roads and platforms under the condition that the station does not stop operating and the existing scale does not change.

The Shenzhen North Railway Station, which has been renovated, has the ability to connect Ganzhou, Maoming, Xili and other directions. 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 were completed and put into production

The State Grid Sichuan Electric Power Company revealed on December 27 that the Sichuan section of the 206-kilometer Yazhong-Jiangxi ±800 kV UHV DC transmission project has been fully connected. This is the first province of the five provinces along the project to achieve line connection.

The Yazhong-Jiangxi ±800 kV UHV DC transmission project is a major power transmission project that serves the national energy strategy of “power transmission from west to east”, guarantees the consumption of clean energy in the west, and meets the green development of the central and eastern regions. It is the fourth project from Sichuan UHV transmission lines.
