On June 14, He Huawu, vice chairman of the Chinese Association of Science and Technology and a member of the Chinese Academy of Engineering, said at the 2019 World Transportation Congress that the further improvement of the speed of the high-speed rail was constrained by factors such as wheel-rail relations, bow-network relations, fluid-solid coupling relationships and operating environment, and that the future of high-speed rail technology should achieve a breakthrough in speed.

High-speed magnetic levitation or low vacuum tube (tunnel) high-speed magnetic levitation railway can be used as the research direction. He Huawu revealed that the Chinese Academy of Engineering led the organization of relevant parties, is carrying out "tube (tunnel) road magnetic levitation traffic development strategy research" "Great Bay Area, Guangzhou-Shenzhen-Hong Kong high-speed magnetic levitation railway pre-research" and other major topics of research, to different high-speed magnetic levitation, combined with low-vacuum pipe (tunnel) road technical routes and key technical issues to fully demonstrate,

To determine the technical and economic feasibility of the project and to carry out a pre-feasibility study on the construction of a high-speed maglev railway in the Guangzhou-Shenzhen-Hong Kong-Shenzhen-Hong Kong Corridor, Guangdong, Hong Kong, Guangdong and Hong Kong. In fact, as early as 1904, the American scholar Robert David put forward the idea of "vacuum pipeline transportation". In recent years, Elon Musk has enriched the concept of "vacuum transportation" and proposed the concept of "super-high-speed rail". The principle is that through the combination of magnetic levitation technology and vacuum environment, to achieve almost zero resistance transport effect, the capsule-shaped cockpit in the vacuum pipe is ejected like a shell, theoretically can reach 1500 kilometers per hour, while passengers in the cockpit can only feel a small burst force. At present, China has Southwest Jiaotong University, China Academy of Engineering, Beijing Jiaotong University, China Aerospace Science and Technology Group and other institutions and enterprises are studying the technology.

The latest news shows that the chinese super maglev train is being developed, "super high-speed rail", using "high temperature superconducting magnetic levitation and vacuum pipeline" technology, the future speed can reach 1000 kilometers per hour, is expected to be as soon as 2 years later into trial.
