The newspaper (Reporter Peng Li) "Air Rail is an important supplement to urban rail transit, it does not change the existing ground transportation pattern at all, it is a new option for the development of three-dimensional traffic in modern cities, and it is alleviating the increasing pressure of urban traffic congestion. Significant. "At the start of the world's first new energy air and rail test line on November 21, Zhai Wanming, chief designer of the new energy air and rail system and academician of the Chinese Academy of Sciences, said that the successful operation of the test line marked that China has become Germany and Japan. The third country to master suspended air rail technology.
"Science News" reporters at the scene test-riding air rail suspended about 5 meters high above the ground. Regarding the slight bumpy feeling during the test ride, Zhai Wanming said that the test line is still in the state of simulating normal passenger operation, and it will conduct repeated tests with a total mileage of 10,000 kilometers to further improve its stability.
It has been estimated that the cost of constructing new energy air rail is only 1/5 to 1/8 of the subway, and 1/2 to 1/3 of the straddling urban light rail. "This is very suitable for China's national conditions. Even empty rails can be directly installed on the green belts of urban busy roads, and it can also be used for promotion in second- and third-tier cities." Zhai Wanming said.
According to reports, the empty rail running mechanism is always enclosed inside the box-shaped track beam, and there will never be a derailment accident. The lithium battery used can be replaced within 1 minute of stopping at the station, and the battery life can reach up to 4 hours depending on the number of passengers. The test line officially put into operation this time is 1.41 kilometers in length, with a maximum speed of 60 kilometers per hour.
Different from the suspended monorail transportation in Germany and Japan, this technology has abandoned the traditional high-voltage power transmission and transformation power supply system, introduced the green new energy concept, and used the large-capacity lithium battery pack as the traction power source for the train. The construction cost is the first in the world.

The test line was invested and built by China Tangkong Railway Group. It adopts the collaborative innovation model of production, education and research. It is jointly developed by Southwest Jiaotong University and China Railway, China Railway, and other key railway transportation enterprises. It has China's completely independent intellectual property rights.
