- China has initiated construction on a new maglev train line, with plans to develop trains capable of reaching speeds up to 621 mph. This project highlights China's ambition to establish a nationwide high-speed maglev network.
- The proposed top speed exceeds the cruising speed of commercial aircraft (480-575 mph), aiming to revolutionize transportation by creating faster, smoother and quieter travel options.
- The new project extends the existing Changsha Maglev Express by approximately 30 miles to Liuyang City, with capabilities to operate at 100 mph. Future plans involve integrating hyperloop-style technology to achieve unprecedented speeds by reducing air resistance in vacuum tubes.
- Chinese researchers propose solutions to overcome communication challenges at ultra-high speeds, using parallel cables to emit electromagnetic signals. However, significant engineering hurdles, such as safety at near-sonic speeds, remain.
- China's $1.44 billion investment in this project aligns with its strategy to create a smart, eco-friendly transportation network. Other countries like Japan and Germany are also exploring maglev technology, though progress has been slower due to financial and infrastructure constraints.
China has commenced construction on a new maglev, or magnetic levitation, train line, marking a significant step forward in its pursuit of ultra-high-speed rail travel. The project aims to develop trains capable of reaching speeds of up to 621 miles per hour (mph).
The proposed top speed of 62 mph would surpass the cruising speed of a normal commercial passenger aircraft, which is anywhere between 480 to 575 mph. This development underscores China’s ambition to create a nationwide network of maglev trains, leveraging advanced magnetic levitation technology to revolutionize transportation.

Maglev trains use superconducting magnets to levitate above the track, eliminating friction and enabling faster, quieter and smoother journeys. The technology has been in use in China since the early 2000s, with the Shanghai Transrapid maglev train – the world’s first commercially operated high-speed maglev – transporting passengers for 18.6 miles at peak speeds of 268 mph.
The new maglev construction project would be an extension of the existing Changsha Maglev Express in the city of the same name in the central Chinese province of Hunan. The current maglev line travels 11.5 miles from Changsha Huanghua International Airport to the Yuhua District in south-central Changsha.
The expansion will extend the line by around 30 miles to the east to Liuyang City. The extension is expected to operate at speeds of approximately 100 mph, though future lines in the maglev network are projected to reach much higher speeds.
China wants to create maglev hyperloop networks
The ultimate goal is to establish a hyperloop-style network, where maglev trains travel through vacuum tubes to minimize air resistance and achieve unprecedented speeds.
This concept, first proposed in 1910 by American engineer Robert Goddard and later popularized by Elon Musk in 2013, could allow maglev trains to travel up to seven times faster than current limits in a closed line. However, significant engineering challenges remain, particularly in maintaining communication systems and ensuring safety at near-sonic speeds.
Researchers from Southeast University, led by Song Tiecheng, have proposed a solution to the communication challenges. They suggest installing two parallel cables along the inner walls of the vacuum tubes to emit electromagnetic signals, thereby minimizing disruptions caused by signal frequency shifts. This innovation is critical for sustaining data transfer and ensuring passenger connectivity at ultra-high speeds.
China’s current non-maglev high-speed rail network operates at speeds of up to 217 mph. The new maglev trains, once operational, will offer a 400 mph increase in speed, significantly reducing travel times between major cities. For instance, a journey from Beijing to Shanghai — a distance of over 620 miles — could take less than two hours, compared to three hours by plane or 5.5 hours by high-speed rail.
While China is a global leader in high-speed rail development, other countries are also exploring maglev technology. Japan, for example, holds the world record for the fastest train, reaching 374 mph on an experimental track in 2016. However, high costs and compatibility issues with existing infrastructure have hindered the widespread adoption of maglev systems. Germany and other nations are also investing in maglev research, but progress has been slower due to these challenges.
The construction of the new maglev line in China is part of a broader strategy to create a smart, environmentally friendly, and energy-efficient transportation network. The project is estimated to cost 10.44 billion yuan ($1.44 billion), reflecting the significant investment required to develop cutting-edge rail technology.
Despite the ambitious timeline and financial demands, China’s efforts could pave the way for a new era of high-speed travel, offering an alternative to air travel for long-distance journeys.
