New energy, empty iron, bright future.

An airborne train has attracted attention in the Southwest Airport Economic Development Zone, the world's first test line for new energy sources. Because the train's exterior design uses a black and white Panda pattern, it is vividly called the "Panda" empty iron.

New energy, empty iron, bright future.

"New energy air rail is a new form of urban rail transit. It belongs to light, medium-speed, and medium-volume public transport. It is not affected by the situation of ground traffic and has safety, green, environmental protection, full automation, all-weather operation, and low cost., cost and high cost. "The chief designer of the new energy air and iron project and chief professor Diwanming of Southwest Jiaotong University said in an interview with reporters.

Fully autonomous intellectual property rights

The expanding car ownership and limited urban road resources have made urban transportation increasingly overwhelmed. How to bring into play the advantages of China's rail transit design, research and development and construction, and improve the efficiency of the city's comprehensive transportation operation?

The establishment of more efficient three-dimensional transportation system is a feasible method. Experts said that the existing underground and ground transportation modes such as subways, light rails, and automobiles in China can open up an air train passage if the rails are supported in the air with pillars to allow trains to operate in suspension.

In order to promote the research and development of the air railway project, Sichuan Zhongtang Air Railway Group initiated and invested, led by the State Key Laboratory of Traction Power of Southwest Jiaotong University, and formed seven companies, including China CNR, China Railway, and Panzhihua Iron and Steel, to form a new energy. Air iron production, learning, and research integration collaborative project platform. Now, the world's first new energy air and iron test line has been put into operation in Chengdu.

It is reported that the design speed of this empty iron test line is 60 kilometers per hour, and the single car is 18 meters long, 2.3 meters wide and has a capacity of 120 people. "The total length of the test line is 1,461 meters, The entire system consists of passenger stations, rail box beams(including piers), right-line track box beams(including piers), curved sections(minimum turning radius of 30 meters), up and down sections(maximum slope of 60 inches), passenger cars, and static storage.(charge Device), high-power lithium battery power pack and other units. "Jiminting, chief engineer of China Railway Baoqiao Group Co., Ltd., who participated in track construction, introduced it.

"This marks that China has become the third country after Germany and Japan to master suspension monorail transportation technology. "Diwanming said. At the same time, because this test line is the first time in the world to use lithium battery packs instead of high-voltage power for suspension train traction, China has completely independent intellectual property rights over related technologies. This is a major innovation in the field of rail transit in China.

Operational safety is fully guaranteed

From afar, the new energy empty iron train is like running on the head of pedestrians. Is this new technology reliable and reliable?

In this regard, Diwanming introduced that when the vehicle is driven, it is always closed inside the box-shaped rail beam. There will be no derailment accident. The train will not run on the air dedicated line and will not collide with other objects. The safety of the operation is fully guaranteed. After the air train was put on the line at the end of September this year, after nearly two months of commissioning, all technical indicators have met the design requirements.

"Standing in the car, the vision is extremely wide, but the bumpy feeling in the car is still more obvious. "A passenger who has experienced the new energy empty iron said.

It is understood that the expert team will continue to test the entire air and iron operating system, including the track system, body system, traction system, signal system, etc., on this test line, and strictly test its technical reliability. According to experts, the biggest risk at present is that the empty iron is running out of electricity. In order to help passengers escape and evacuate, the carriages can open the Windows back and forth in emergency situations, and passengers can be evacuated through slides or simple ladders. Another empty train can also pick up the trapped passengers to ensure the safe evacuation of passengers.

What are the advantages of new energy empty iron

At present, the new energy empty iron is still in the stage of technical inspection and optimization on the test line. What are the advantages of the new energy empty iron if it is commercialized in the future?

In this regard, experts analyzed that compared to subways, urban light rails and maglev trains, the biggest advantage of new energy empty iron is its wide adaptability. Its minimum turning radius is only 30 meters, which has greater flexibility in the selection of urban rail transit lines. Can minimize the amount of demolition.

In terms of cost and efficiency, compared with the large investment in the construction of subways, the new energy empty iron tracks and beams are prefabricated by factories, on-site assembly, simple construction, and less impact on the surrounding areas. The construction period is shorter. Moreover, because the train uses battery traction, it can store electrical energy at the low point of electricity use in the evening, and it is green and environmentally friendly.

However, compared to the subway, there are still gaps in the volume of new energy air railways. "Air rail is one of the many modes of transportation and is an important supplement to urban rail transit. Mr Diwanming said the new energy, empty rail, as a modern new type of transportation, would have a broad market in the future in areas such as three-dimensional traffic connections between urban and rural areas and intercity cities, integrated connections between central urban transportation hubs, and transportation of hot tourist attractions.
