Guangzhou, Shenzhen and Hong Kong plan to build a maglev line with a designed speed of 650 kilometers per hour

According to Yangcheng Evening News, in order to improve transportation convenience and interconnection within the Guangdong-Hong Kong-Macao Greater Bay Area, the four cities of Guangzhou, Shenzhen, Hong Kong and Macao are planning to build high-speed maglev transportation projects to achieve the goal of integrating the city in half an hour

Chen Xiangsheng, an academician of the Chinese Academy of Engineering, revealed at the 36th "Flower City Academician Forum" held in Guangzhou that he is thinking and studying maglev transportation in the Guangdong-Hong Kong-Macao Greater Bay Area and has proposed four research plans

It is reported that the Guangzhou-Shenzhen-Hong Kong main axis is located in the knowledge-intensive industrial corridor with the most developed economy and the highest concentration of unit population in the Greater Bay Area. In 2017, the passenger flow density was 109.63 million people, which has become saturated. In 2035, the passenger flow density on the Guangzhou-Shenzhen-Hong Kong main axis will reach 260 million people, leaving a capacity gap of approximately 40 million people. Therefore, a new expressway project is needed to meet the transportation needs of Guangzhou, Shenzhen and Hong Kong. In addition, the passenger flow connection between the main urban centers of the eight cities also requires expressways to solve the problem of unbalanced and inadequate development.

According to Chen Xiangsheng, the Guangzhou-Shenzhen-Hong Kong Maglev has multiple line options. The designed speed of the line is up to 650 kilometers per hour. There are currently 4 alternative options: The first option is the east line The Xiangmi Lake plan is the Guangzhou East Railway Station - Dongguan Guancheng - Shenzhen Xiangmi Lake; the second plan is the east line passing through Qianhai plan, which is the Guangzhou East Railway Station - Dongguan Humen - Shenzhen Qianhai; the third plan is the west line passing through Zhujiang New Town , that is, Zhujiang New Town - Guangzhou Nansha - Shenzhen Qianhai; Plan 4 is the west line via Guangzhou Station, that is, Guangzhou Station - Guangzhou Nansha - Shenzhen Qianhai.

Chen Xiangsheng said that the current option one is the preferred option, but it is still unclear whether it will be implemented. He also said, "In addition to Guangzhou and Shenzhen, Shanghai-Hangzhou, Chengdu and Chongqing are also planning to build maglev lines. It depends on Who can take the lead?"

According to Xinhua News Agency reports in March this year, my country has successfully realized the first independently developed suspended transportation system with an operating speed of 600km/h. The system uses high-temperature superconducting electric suspension technology to achieve suspension operation through passive suspension without active control. It has the advantages of large suspension and guide clearance, strong adaptability, large space for speed increase, strong vehicle emergency operation capability, and high safety.
