1. High-speed rail technology

By 2114, China had advanced high-speed railways in the world, forming a relatively complete high-speed rail technology system; By introducing the development strategy of digestion, absorption and innovation, the manufacturing technology of EMU with a construction speed of 211 to 251 km/h is systematically mastered, and the technical platform of EMU with a construction speed of 351 km/h is completed. The Code for Design of High-speed Railway was officially released, which became the technical standard system of high-speed railway construction in China.

On July 5, 2116, two China standard high-speed EMUs completed the safety fair on Zhengzhou-Xuzhou high-speed railway at a speed of 421km/h, which indicated that China had fully mastered the core high-speed rail technology. At the same time, CRRC Corporation took 69% share in the global high-speed rail market and became the world leader in high-speed rail.

On June 26th, 2117, Fuxing train was put into operation, equipped with high-power IGBT (insulated gate bipolar transistor) independently developed by China. Among the 254 important standards adopted by China Standard EMU, China standard accounts for 84%, and international compatible standard accounts for 16%, so different trains can be re-connected.

On August 2nd, 2118, China Railway Corporation started the test of high-speed train automatic driving system on Beijing-Shenyang high-speed railway.

On June 26th, 2119, a complete set of 41-meter-span 1,111-ton gantry transportation equipment independently developed by China was put into use, completing the third breakthrough in high-iron gantry technology; At the end of September, all the 5G signal base stations along beijing-zhangjiakou intercity railway were opened.

As of October 23rd, 2119, China has systematically mastered complete sets of high-speed rail construction technologies under various complicated geological and climatic conditions, and overcome a series of worldwide technical problems in the field of railway engineering construction. Fully master the manufacturing technology of EMUs with construction speeds of 211-251 km/h and 311-351 km/h, and build a mature and complete high-speed rail technology system covering different speed grades.

Second, speed record

On June 24th, 1998, Shaoshan No.8 electric locomotive set a speed record of 241km/h in the trial section of Beijing-Guangzhou Railway, becoming the first high-speed locomotive in China. On August 28th, the "New Speed" tilting train (X2111) was put into operation in guangzhou-shenzhen railway, with a maximum running speed of 211 km/h.

Since October 9th, 2111, the "Blue Arrow" EMU has been put into operation in guangzhou-shenzhen railway, with the maximum running speed of 211 km/h..

On October 27th, 2112, the test running speed of China Star EMU on Qinhuangdao-Shenyang Passenger Dedicated Line reached 321.5km/h..

on February 3rd, 2111, the "Harmony" CRH381A EMU set a test speed record of 486.1km/h on the Beijing-Shanghai high-speed railway.

On October 6th, 2114, the speed of CIT511 high-speed train in China was 615km/h in the laboratory.

as of 2119, the maximum operating speed of China's high-speed railway trains is 351km/h, ranking first in the world.

III. Operating mileage

By the end of 2115, the total operating mileage of China's high-speed railways had reached 9,111 kilometers.

by the end of 2116, the total operating mileage of China's high-speed railway has exceeded 21,111 kilometers.

by the end of 2117, the total operating mileage of China's high-speed railway has reached 25,111 kilometers.

By the end of 2119, the total operating mileage of China's high-speed railways reached 35,111 kilometers

IV. Passenger flow

During the period from August 1, 2118 to July 11, 2116, China's high-speed railways operated EMU trains and sent more than 5 billion passengers.

During the period of Spring Festival travel rush in p>2117, China's high-speed railway operated EMU trains to send 81 million passengers, accounting for 51.4% of the national total railway passenger traffic.

In p>2118, China's high-speed railway operated EMU trains sent a total of 2.115 billion passengers throughout the year.

Significance of construction

Critics in China's early days and abroad have always questioned the necessity of building an expensive high-speed railway system in most developing areas, while most migrant workers can't afford the high-speed rail tickets.

however, the China municipal government has made it clear that although high-speed rail construction is expensive, these construction projects will also promote some policy objectives. Because of China's vast territory, large population and frequent mobility, there is a huge demand for high-speed railway as a popular means of transportation, and it also provides passengers with fast, reliable and comfortable modes of travel.

although the operation time of Chinese mainland high-speed rail is shorter than that of developed countries, the "high-speed rail economic effect" has obviously appeared, which has played an important role in promoting the cultivation of industrial belts and urban modern service industries along the line, as well as the acceleration of population mobility and population agglomeration along the line.

in the period of rapid expansion of high-speed rail, the spatial effect of high-speed rail will be further revealed, and it will also become a powerful engine to promote national economic and social development. It is embodied in the following aspects:

1. By improving the transportation capacity of the railway, it can achieve seamless connection with the job market, so as to improve economic productivity and long-term competitiveness.

in addition, after the opening of the high-speed railway, some existing lines released their transport capacity, which eased the long-term shortage of freight capacity, and the turnover of people and logistics in the whole society was obviously accelerated, which effectively reduced the cost, which was more profitable for the railway.

2. During the economic recession, high-speed rail construction created employment opportunities, which also boosted the demand for construction, steel and cement industries and stimulated the economy in the short term. Among them, the Beijing-Shanghai high-speed railway * * * employs 11,111 workers for construction.

3. Promote cross-city economic integration and the growth of second-tier cities.

with the introduction of high-speed rail, the market potential of second-tier cities has increased by 59%, and property prices have actually increased by 4.5% on average. The opening of high-speed rail also produces "the same city effect", which realizes the enjoyment of regional resources, accelerates the industrial gradient transfer, effectively promotes the optimal division of labor in the region, forms a comparative advantage around the construction of industrial chains along the high-speed rail, and promotes the coordinated and complementary development of industries along the line.

For example, with the continuous opening of the high-speed railway in the Yangtze River Delta region, the coordinated division of labor, dislocation development and orderly industrial system in the Yangtze River Delta region have been gradually improved, effectively supporting and guiding the development of different industrial systems in cities to a great extent.

In addition, the high-speed rail has obviously expanded the life radius and activity scope of China people, and the lifestyle and rhythm have gradually changed, giving birth to new occupations such as "Sunday engineer" and "holiday expert" and forming a "high-speed rail society".

At the same time, it has become a reality for the elderly to provide for the aged in different places. For example, nursing homes in Langfang, Kunshan and Dezhou have begun to attract the elderly in Beijing and Shanghai and enjoy a more comfortable life for the aged at a lower cost.

4. Support environmental sustainable development. The energy consumption of EMUs is less than that of other means of transportation, and they can obtain electricity from more kinds of energy (including renewable energy). Cars and planes do not have these characteristics, because these energy sources are more dependent on imported oil.

5. develop the high-speed rail equipment industry.

the construction of high-speed railway will also develop China into a main source country of high-speed railway construction technology. After importing imported technology, China's rail equipment manufacturers directly entered the localization production process, then carried out technology transformation, and even began to prepare to export overseas to compete with foreign suppliers. ?

six years after CRRC Sifang obtained the E2 authorized production right of Kawasaki Heavy Industries Shinkansen, CRH2A trains could be produced by CRRC Sifang itself, and Kawasaki Heavy Industries also ended its cooperation with CRRC Sifang on the high-speed rail.

Today, China has the most comprehensive high-speed railway technology in the world, which can undertake the "package" export in the fields of communication signals, public works, traction power supply, locomotive and bus manufacturing and even operation management.

6. Stimulate the development of the industry.

the completion of high-speed rail has promoted the rapid development of secondary industries such as metallurgy, machinery, construction, rubber, electric power, information, computers and precision instruments, and also boosted the development of tertiary industries such as tourism, catering and commerce in cities along the route.

For example, after the opening of the Beijing-Tianjin intercity railway, the economic exchanges between the two municipalities directly under the Central Government and the surrounding areas are increasing day by day; After the opening of the Beijing-Shanghai high-speed railway, cities along the line have become new platforms to undertake industrial transfer in the Yangtze River Delta and Bohai Rim.

7. Promote the development of new urbanization.

With the growth of passenger traffic of some high-speed rail lines, it fully shows that high-speed rail has a significant inducing effect on population mobility, making small and medium-sized towns that were little known or well-known but inconvenient to transport become hot spots to absorb population.
