Rail transit is the main artery of regional linkage development. In recent years, Shenzhen has vigorously promoted the construction of the Greater Bay Area on rails, helping to comprehensively build an integrated Bay Area transportation network, and striving to achieve half an hour of transportation in the Bay Area and one hour in the Bay Area. While improving the city's functions, it has greatly improved the distance between cities Traffic efficiency, continuously deepen the interconnection of people flow, logistics, and capital flow in the Bay Area, and activate the vitality of the Bay Area.

Today, the construction of the three railways in the Greater Bay Area goes hand in hand, with the development of national railways, the construction of intercity railways, and the great leap of urban rails. According to the plan, there will be more than 30 railways and intercity rail lines in the Guangdong-Hong Kong-Macao Greater Bay Area in the future, and the operating mileage will exceed 5,000 kilometers. The Bay Area is well-connected and traffic is first. With the extension of the track, the high-quality development of the Guangdong-Hong Kong-Macao Greater Bay Area is already on the way.

The comprehensive rail network in the Bay Area drives the aggregation of urban agglomerations

On February 16, 2023, after 10 hours of continuous hard work, the pouring of the first super-large-diameter pile foundation of 4 meters above water for the main tower pier of the Hongqili Waterway Highway-Railway Bridge on the Shenjiang Railway undertaken by the China Railway Bridge Bureau was successfully completed. This pouring is an important node in the construction of the project, laying a solid foundation for the smooth development of the subsequent water pile foundation construction of the Shenjiang Railway Bridge, and also marking that the construction of the railway bridge has entered a critical stage. The relevant person in charge of the Shenzhen Municipal Bureau of Transportation introduced.

It is reported that the Shenzhen-Shantou high-speed railway, another important rail transit project in the Greater Bay Area, has recently started construction. The Shenzhen-Shantou Railway starts from the Shenshan Station of the Guangzhou-Shantou Railway, passes through the Shenzhen-Shantou Cooperation Zone and Huizhou City, and ends at the Shenzhen Hub Xili Station. It has a total length of 125.5 kilometers and a speed of 350 kilometers per hour. It will connect multiple national railways, intercity and subway tracks in series. lines to form an integrated network.

The accelerated construction of the Shenjiang and Shenshan railways has opened up the east-west railway passages, making the cities in the Guangdong-Hong Kong-Macao Greater Bay Area infinitely closer in terms of "physical" and "psychological" distances, and will form a strong functional aggregation of urban agglomerations in the future. Among them, the Shenjiang Railway will enhance the high-speed direct connection between Shenzhen and the western Guangdong area, as well as the railway connection between the urban agglomerations on both sides of the Pearl River, making the integration between Shenzhen and Guangzhou, the first-tier cities in the bay area, more efficient; the Shenshan Railway will The national coastal high-speed rail channel will be unblocked, and the high-speed connection between the Greater Bay Area and the Yangtze River Delta and the Hercynian Economic Belt will be realized, as well as the high-speed and high-frequency railway connection between Shenzhen and Shenshan Special Cooperation Section.

Facilitation of cross-city commuting in the Shenzhen metropolitan area

The Guangzhou-Shenzhen Intercity Railway, which has been in operation in recent years, has now become a fast rail transit channel connecting Shenzhen, Guangzhou and Dongguan. "It only takes more than one hour from Shenzhen Airport to Guangzhou East Railway Station, and it takes only 22 minutes to get to Humen North, and it is operated by public transportation. With this intercity, there is another express line between Shenzhen, Dongguan and Guangzhou. The more convenient it is!" Mr. Zhou, a Shenzhen citizen who often commutes in the Pearl River Delta, told reporters. An intercity railway connects economically developed city groups on the east bank of the Pearl River, and the one-hour economic and living circle in the Greater Bay Area has become a reality.

In 2023, the construction of intercity railways in the Greater Bay Area will enter the fast lane. In addition to the lines that have been started before, the construction of five intercity railways, including the front section of the Guangzhou-Dongguan-Shenzhen Intercity Airport, the Qianhuang Section of the Guangzhou-Dongguan-Shenzhen Intercity, the Shenzhen-University Intercity, the Shenzhen-Huizhou Intercity and the Dapeng Branch Line, has started.

During the "14th Five-Year Plan" period, Shenzhen will enter the peak period of intercity railway construction, will promote the inclusion of the Shenzhen-Guangzhou central axis intercity railway into the upper-level planning, and accelerate the planning and construction of Shenzhen-Dongguan intercity and Changlong intercity projects. The relevant person in charge of the Shenzhen Railway Office said that the construction of the intercity railway network will help to comprehensively build an integrated Bay Area transportation interconnection network, adhere to the joint construction and sharing of regional transportation, innovate regional transportation cooperation models, connect the Greater Bay Area, and radiate the whole of China. Build the Shenzhen metropolitan area.

As Shenzhen and Hong Kong fully resume normal customs clearance, the connection between Shenzhen and Hong Kong continues to deepen. In the development strategy of the northern metropolitan area of Hong Kong, five key rail transit projects are proposed, most of which involve Shenzhen. Hong Kong and Shenzhen have jointly established a special team to promote the construction of Hong Kong-Shenzhen cross-border rail infrastructure, and actively promote the planning and construction of the Hong Kong-Shenzhen Western Railway and the introduction of Hong Kong’s Northern Link branch into Huanggang Port. Among them, the Hong Kong-Shenzhen Western Railway (Shuishuiqiao to Qianhai) project is in continuous progress. The first phase of research work has been completed a few days ago, and the second phase of research will start early this year and is expected to be completed in 2024.

In 2025, the Greater Bay Area will achieve full coverage of the railway network

According to the "Shenzhen Comprehensive Transportation "14th Five-Year" Plan", during the "14th Five-Year Plan" period, Shenzhen will vigorously promote the construction of the fourth-phase adjustment project of urban rail, accelerate the preparation and implementation of the fifth-phase planning, and at the same time improve the "north-south final arrival, The layout of the high-speed rail channel that connects east and west and connects each other supports Shenzhen to accelerate the integration of the Bay Area.

In terms of cross-city national railways and intercity railways, according to the plan, a total of 15 national railways and intercity railways will be formed between Shenzhen, Dongguan and Huizhou. Among them, there are 4 national railways and 5 intercity lines between Shenzhen and Dongguan, and 5 national railways and 3 intercity lines between Shenzhen and Huizhou. In terms of inter-city urban rail, according to the Shenzhen Rail Transit Network Planning (2016-2035), Shenzhen, Dongguan, and Huizhou plan a total of 17 inter-city rail lines for connection. By 2025, the planned mileage of the railway network in operation and under construction in the Greater Bay Area will reach 4,700 kilometers, covering the entire Bay Area.

Across the Bay Area, from south to north, from west to east, under the continuous weaving of the rail network, high-speed trains will connect more cities that are taking off, and the Greater Bay Area on the rails is gradually turning from blueprint to reality . Editor / Zhao E
