The magnetic suspension line design plan connecting Guangzhou, Shenzhen, and Hong Kong appeared in early August.This plan aims to further promote the interconnection of cities in the Guangdong -Hong Kong -Macao Greater Bay Area and achieve half an hour of cityization for Guangshen and Hong Kong.

Scholars of interviewees believe that the magnetic suspension rail transit is the field where China seeks technological breakthrough next. The Guangshen port line must be connected with other urban agglomerations in China to play a greater role.

According to the Guangzhou Daily, Chen Xiangsheng, an academician of the Chinese Academy of Engineering and the dean of the School of Civil and Transportation Engineering of Shenzhen University, introduced the plan for the construction of a magnetic suspension train in the Greater Bay Area on August 5th on August 5th, and demonstrated four obediences.The route design plan to Shenzhen to Shenzhen.

The

plan shows that the starting point of Guangzhou's candidates includes Guangzhou East Railway Station, Pearl River New City, and Guangzhou Station; candidate stations in the middle include Dongguan Guancheng, Humen, and Guangzhou Nansha; Shenzhen candidates include Shenzhen Qianhai and Xiangmi Lake.All four schemes are reserved to the north to Guangzhou Baiyun Airport, and to the south to Kowloon, Hong Kong.

According to reports, the route of Guangzhou East Railway Station -Dongguan Guancheng -Shenzhen Xiangmi Lake is currently a preferred plan. Whether it will eventually be adopted and the implementation timetable has not been determined.

Chen Xiangsheng pointed out that Guangshen and Hong Kong are the most densely populated industrial corridor in the Guangdong -Hong Kong -Macao Greater Bay Area. Its passenger flow density reached 1109.63 million as early as 2017, which has tended to be saturated.He predicts that the density of passenger flow in the area will reach 260 million in 2035, and the traffic capacity will have a gap of about 40 million people. Therefore, a new high -speed magnetic suspension project will be added to meet the needs of transportation.

Guo Wanda, Executive Deputy Dean of Shenzhen Comprehensive Development Research Institute, pointed out in an interview with Lianhe Zaobao that as a candidate station in the plan, in addition to the free trade pilot zone in Guangdong Province, Shenzhen Qianhai and Guangzhou Nanshatransportation hub.

He said that the suspension of magnetic suspension trains in these places will improve the connection of transportation hubs. Increased personnel flow will play a role in radiation and promote the development of economic, social, and science and technology.

In fact, China ’s concept of magnetic suspension rail transit was formed a few years ago.The official plan for the first time in February 2021 faced the application of non -wheeled rail technology rail transit applications, and proposed that "study and promote the layout of high -speed magnetic floating channels and test lines between large cities."

In the planning of urban space in the same year in the same year, Guangdong Province also proposed to reserve six super corridors, including Beijing -Hong Kong -Macao high -speed magnetic suspension and Shanghai (Shenzhen) Guang high -speed magnetic suspension.

In addition to the Guangshen Port, the urban districts such as Shanghai and Hangzhou, Chengdu and Chongqing are also exploring the construction of a magnetic suspension train.

Gu Qingyang, an associate professor of the School of Public Policy of the National University of Singapore, pointed out in an interview that the development ideas in China for more than a decade are to build urban agglomerations and focus on developing the economy of these places.

He said: "To further improve the economic cohesion between urban agglomerations, it is necessary to launch faster and convenient transportation like magnetic suspension trains to close the connection between urban agglomerations."

Magnetic suspension trains realize the non -contact suspension and orientation between the train and the track through electromagnetic force, and use the electromagnetic traction train generated by a linear motor to run.Different from other rail transits, the magnetic suspended trains suspended in the air reduce the friction during the runtime, which is the fastest ground transportation at present.

Chen Xiangsheng said that the design of the Guangshen Hong Kong magnetic suspension line is 650 kilometers per hour, which is more than twice as faster than the high -speed railway, which means that the commute time of the Guanggang railway can be shortened from one hour to half an hour.

However, because the current magnetic suspension line design plan does not have cross -city groups, some scholars believe that the value of magnetic suspension trains in a short distance itinerary is not high.

Zheng Tianxiang, a professor at the Research Center of the Hong Kong, Macao and Pearl River Delta Research Center of Sun Yat -sen University, said in an interview that although the speed of the magnetic suspension train can reach 650 kilometers per hour, considering that the distance from Guangzhou to Hong Kong is only more than 100 kilometers, and the train must slow down when entering and exiting the station.There are very few opportunities for trains to reach the highest speed, and there are not much time to save.

Zheng Tianxiang judged that the current line design plan is to pave the way for the longer -term planning in the future.He said: "The official goal is to build magnetic suspension in the densely populated urban agglomeration, and then connect them to give full play to the benefits of magnetic suspension."

Magnetic suspended trains require specialized infrastructure. Excessive cost cost is one of the biggest problems facing the project.According to the Beijing Commercial Daily, the cost of 300 million yuan (RMB, the same, the same, S $ 56 million) or more per kilometer (RMB, the same below, the same below, the same below, the same, the same, the same, the same, the same, the same, the same, the same, the same, and the S $ 56 million) is almost two to three times that of the high -speed rail construction investment.

Gu Qingyang analyzed that high cost means that the magnetic suspension train plan can only be implemented in some richer areas.He said that many local governments are currently facing fiscal pressure, and some of the small cities with fiscal surplus in the Guangdong -Hong Kong -Macao Greater Bay Area and the Yangtze River Delta are the most likely to afford construction costs. The possibility of starting in the next few years is greater.Essence

From the strategic level, Gu Qingyang believes that after the high -speed rail, China has been looking for the next opportunity to emerge.After the trials and experiments of magnetic suspension trains in the past few years, they already have technical conditions and application scenarios in this area.

He said: "Under the pressure of the external environment, China may want to find a breakthrough in this new field and achieve the ambition similar to the high -speed rail."
