Chengdu Guiyang high speed railway opens to create a green development road for Sichuan, Yunnan and Guizhou provinces

On December 16, Chengdu Guiyang high speed railway, the first green mountain railway in China, was officially put into operation, ending the history of no high speed railway in Yibin, North Zhaotong and Bijie in western Guizhou. It is of great significance for poverty alleviation and economic development of areas along the line in the contiguous special and difficult areas of Wumengshan, and will help the southwest to enter the "fast lane" of development.

Chengdu Guiyang high speed railway starts in Chengdu, Sichuan Province, passes Meishan, Leshan and Yibin, Weixin County, Zhenxiong County, Zhaotong City, Yunnan Province, Bijie City, Guizhou Province, and ends in Guiyang city. The total length of the line is 648 km, and the design speed is 250 km / h. The altitude along the

Chengdu Guiyang high speed railway is high, the terrain is extremely complex and dangerous, of which 60% are tunnels, the design and construction difficulty is unprecedented, so it is called "high speed railway on cloud". In order to protect the ecological environment along the line, creec has designed the line in strict accordance with the guidelines for green channel construction of railway engineering, and successfully bypassed 17 ecological environment sensitive areas in Leshan Yibin section. At the same time, the energy-saving autotransformer is used in the traction power supply system of Leshan Yibin section of Chengdu Guiyang railway for the first time, which can save electricity by 710000 kWh and reduce carbon dioxide emissions by 707.5 tons every year. The report of the 19th National Congress of

clearly points out that: accelerate the establishment of the legal system and policy guidance of green production and consumption, and establish and improve the economic system of green low-carbon circular development. China Railway always adheres to the concept of green development, while providing people with efficient and convenient travel, it continues to make efforts in energy conservation and environmental protection. The running resistance of China standard EMU Fuxing is 12% lower than that of harmony, and the per capita energy consumption per hundred kilometers is 17% lower. When it runs at 350 kilometers per hour, the per capita energy consumption per hundred kilometers is only 3.8 kwh, saving more than 5000 kwh for a round trip to Beijing and Shanghai. With the development of human economy and society, the problem of environmental pollution and resource exhaustion is becoming more and more serious, so it is urgent to take the road of sustainable development. Railway transportation has the advantages of large transportation capacity, low cost, good safety, energy saving and so on, which plays an important role in promoting the sustainable development of economy. The opening and operation of Chengdu Guiyang high-speed railway will add a touch of green to the tourism development, economic and social development of Southwest China, and will certainly become a bright star on the green development road of China's high-speed railway.
