　　Statistics show that the coverage of China's railway network in cities with a population of more than 200,000 has expanded from 94% in 2012 to 98% in 2019, and the coverage of high-speed rail networks in cities with a population of more than 500,000 has increased from 28% in 2012 to 86 in 2019. %; Hong Kong enters the national high-speed rail network; all capital cities except Lhasa have high-speed rail; Beijing-Tianjin-Hebei, Yangtze River Delta and other urban agglomerations within two hours; Beijing, Shanghai and other large cities can reach 1,000 kilometers, 4 hours, and 2000 kilometers 8 hours accessible.

　　As of the end of July this year, my country's railway operating mileage reached 141,400 kilometers, ranking second in the world, of which high-speed railway mileage was 36,000 kilometers, ranking first in the world. The "Planning Outline" proposes that by 2035, China's modern railway network will be the first to be built, achieving domestic and foreign interconnection of the railway network, smooth inter-regional multi-roads, efficient connection of provincial capitals, rapid access to cities and counties, basic coverage of counties, smooth connection of hubs, and smooth network connections. The facilities are upgraded intelligently and the effective supply capacity is abundant.

　　"By 2035, the national railway network will reach about 200,000 kilometers, including about 70,000 kilometers of high-speed railways. Railway coverage will be achieved in cities with a population of more than 200,000, and high-speed railways will be accessible to cities with a population of more than 500,000. By 2050, a more developed and complete modern railway will be built. Internet.” said Ding Liang, deputy director of the Development and Reform Department of China Railway Group.

　　According to reports, China Railway Group will focus on "3 networks + modern hub system" to build a world-class network of railway facilities:

　　The first is to build a modern and efficient high-speed railway network, realize high-speed rail connections between provincial capital cities and cities with a population of more than 500,000, basically realize a 3-hour high-speed rail circle between provincial capitals in adjacent regions, and develop high-speed railways with higher speed standards.

　　The second is to form a general-speed railway network with extensive coverage. Construct a general rail network with general rail lines as the framework and regional general rail connections to collect and distribute, connect cities with a population of more than 200,000, resource-rich areas, major cargo distribution centers, major ports and ports, and basically cover administrative areas above the county level. The focus is to strengthen the external channels in the central and western regions, improve the capabilities of the Yangtze River, new land-sea channels in the west, and coal transportation channels, promote the interconnection of surrounding railways, build regional development railways in line with the needs of regional development, implement the transformation and upgrade of existing lines, and strengthen multimodal transportation" One kilometer before and after the construction of a dedicated line.

　　The third is to develop a fast and integrated inter-city (suburban) railway network. In the economically developed and densely populated urbanized areas, make overall plans for the construction of intercity and urban (suburban) railways. "One-hour access to major urban areas (suburbs): such as the Beijing-Tianjin-Hebei region between Beijing and Tianjin and Xiong'an, the Yangtze River Delta region between Shanghai and Suzhou, Wuxi and Changzhou, the Guangdong-Hong Kong-Macao Greater Bay Area between Guangzhou-Shenzhen and Guangzhou-Zhuhai, and the Chengdu-Chongqing Twin City Economic Circle Chengdu and Chongqing form a city area and commuter passenger flow circle; the second is the 2-hour accessibility between major cities in the city group: such as the Beijing-Tianjin-Hebei region between Beijing and Shijiazhuang, the Yangtze River Delta region between Shanghai and Nanjing, Hangzhou, Guangdong-Hong Kong-Macao Greater Bay Area Guangshen Between Hong Kong, Macau and the surrounding cities in the Pearl River Delta, the Chengdu-Chongqing Double-City Economic Circle has formed a fast-track urban agglomeration between Chengdu-Chongqing and surrounding cities; the third is the 3-hour accessibility between neighboring urban agglomerations and provincial capitals." Director of Passenger Operations and Sales Department, Passenger Transport Department, China Railway Group Qiang Lixia said.

　　The fourth is to build an integrated modern comprehensive hub. In accordance with the requirements of "zero distance" transfer, build a group of comprehensive passenger transport hubs centered on railway passenger stations, and promote the integration of the four networks of arterial lines, intercity, urban (suburban) railways, urban rail transit, and efficient connections at airports.

Faster, greener, smarter

——The 400km/h high-speed train is being demonstrated

　　In the past 10 years of operation of China's high-speed rail, EMU technology has gone from early technology introduction to digestion, absorption and re-innovation, and then the Fuxing EMU has fully owned core technologies and realized independent intellectual property rights. China's high-speed rail has taken a key step from catching up to leading the way and gradually formed The serialized products of EMUs with a speed of 350 kilometers per hour and 250 kilometers per hour mainly cover different operating environments such as low temperature, high altitude, sandstorm, and high temperature.

　　"At present, the number of EMUs in China has reached more than 3,600, of which about 690 EMUs of Fuxing, accounting for more than half of the total number of high-speed trains in the world, more than the total number of other countries." Deputy Director Wu Guodong said, but "higher operating speed, more energy-saving and environmentally friendly, more comfortable riding experience, smarter equipment and facilities, and lower life cycle costs are still the goals pursued by China's railways."

　　In recent years, my country's railways have continued to increase investment in scientific and technological innovation, cultivate innovative talents, accelerate the research and development of key technological products and the promotion and application of innovative results, and the leading role of scientific and technological innovation has become increasingly prominent. "At present, China has successfully developed an intelligent Fuxing EMU with functions of self-perception of working status, self-diagnosis of operating faults, and safety-oriented self-decision-making functions. It has been successfully applied to the Beijing-Zhangjiakou High-speed Railway and has achieved automatic driving at a speed of 350 kilometers per hour. The country is still in the experimental stage in terms of smart passenger cars." said Jia Guangzhi, deputy director of the Information Institute of China Academy of Railway Sciences Group Co., Ltd.

　　At present, the Beijing-Zhangjiakou high-speed rail intelligent EMUs have been put into use in small batches on the Beijing-Zhangjiakou high-speed rail, and the Jingxiong Intercity Intelligent EMUs are planned to be put into use at the Beijing-Xiong Intercity Intercity, which will be opened at the end of this year. "By 2035, China's intelligent high-speed rail will be the first to be completed. China's railways will realize the automatic driving function at a speed of 350 kilometers per hour, and the high-speed rail will achieve intelligent dispatching and centralization, and the train operation can be optimized and adjusted intelligently in real time." Security Director Zhang Boju said.

　　"The "Planning Outline" proposes independent research and development of a new intelligent train control system. The new intelligent train control system will use Beidou satellite navigation technology, 5G communication technology, etc. to form an integrated air-space-ground train control system." China Railway Group's Ministry of Industry and Electricity Communications Signal Division Director Mo Zhisong said.

　　It is understood that the new train control system will shorten the train tracking interval from the current shortest 3 minutes to about 2 minutes, and increase the line's transportation capacity by more than 30%. "The new train control system will be a future-oriented train control system. It will be able to realize the internal recycling of electric energy when one batch of cars accelerates out of the station and another batch of cars arrives to decelerate. In theory, the energy consumption per 100 kilometers per capita can be reduced by about 30%. Taking the Beijing-Shanghai high-speed railway as an example, if the new train control system is adopted, the EMU can save about 9,000 degrees of electricity once it runs back and forth." Mo Zhisong said.

　　The reporter noted that the "Planning Outline" clearly stated that it is necessary to "independently innovate and establish a complete set of key technology systems for high-speed railways with speeds of 400 kilometers per hour and above, faster freight trains, and more advanced heavy-haul railways." In this regard, Wu Guodong said: "The 400-kilometer high-speed train is under evaluation, and the speed class has not yet been determined, but it will definitely be finalized by taking into account comprehensive factors such as environmental protection and economy."
