What are the important stages of China s high speed rail growth?

Went through a lot of important stages. China's railway construction in the last years of the Qing Dynasty, in 1881, the construction of the Tangshan to Xugezhuang railway, in 1909 when the design of the Beijing-Zhangjiakou railway, in July 1, 1952 when the Chengdu-Chongqing railway was successfully opened to traffic, in 1958 when the construction of China's first desert railway, in 1975 the construction of China's first electrified railway, from 1997 to 2007 the railway appeared six times of speed. In the continuous breakthrough, a lot of high-speed railways and bullet trains have been created, and now China has ranked among the top in the world in terms of railways.

The development of high-speed rail has gone through four more important stages, which are the preparatory stage, the transition stage, the high-speed railway, and finally going abroad, which shows that China's high-speed rail is very complex in the process of development, and it has also experienced many people's doubts.

A brief history of China's high-speed rail development:

During the period from 1991 to 1991, China began to plan for high-speed rail technology research and experimental practice, with the Guangzhou-Shenzhen Railway as the pilot line for high-speed transformation, and the Beijing-Shanghai line was preferentially selected.

The Beijing-Tianjin section and the Shanghai-Nanjing section are designed for high-speed railways. The Shenzhen Railway started the quasi-high-speed transformation and became the first quasi-high-speed railway project in China.

China and South Korea jointly developed high-speed trains and conducted tests on the Guangzhou-Shenzhen Railway.

On August 28, the maximum speed of the Guangzhou-Shenzhen Railway was 200 kilometers per hour, becoming the first railway in China to reach the high-speed index. In December, the Beijing-Shanghai high-speed railway.

The project has two mutually exclusive controversial schemes, "traditional wheel-rail technology" and "maglev track technology", which have led to the long-term shelving of the project, and at the same time, it has also dominated China's high-speed railway.

The direction of development.

On August 16, the construction of the Qinshen Passenger Dedicated Line started as China's first wheel-rail high-speed EMU.

of the test line.

On December 31, the Shanghai Maglev Train Demonstration Line was completed, with a design speed of 430 kilometers per hour, making it the first high-speed rail system in China.

On October 11, the entire section of the Qinshen Passenger Line was completed and opened to traffic, with a design speed of 250 kilometers per hour, making it the first high-speed national railway line in China.

On June 11, the construction of the Shitai high-speed railway began, and China officially entered the stage of standardized construction of high-speed passenger dedicated railway.

On January 5, Taiwan's high-speed railway.

It was put into trial operation and became the first high-speed railway in China with a design speed of 300 kilometers per hour. April 18, China Railway.

The sixth large-scale acceleration was launched, with the maximum operating speed of 250 kilometers per hour in some sections, and China began to take shape for the first time in some parts of the country to run EMU trains with an operating speed of 200 kilometers per hour, and China's railways began to enter the high-speed era.

On August 1, the Beijing-Tianjin Intercity Railway was put into operation, becoming the first high-speed railway in Chinese mainland with a design speed of 350 km/h.

On December 26, the Beijing-Guangzhou high-speed railway.

The Wuhan-Guangzhou section was put into operation, with a maximum operating speed of 350 kilometers per hour, breaking the bottleneck of China's railway spring transportation for the first time, and high-speed rail transportation occupies an important position on the trunk railway, marking China's official entry into the era of high-speed rail.

On December 28, the Shiji high-speed railway was put into operation, and so far, the "four horizontal and four vertical" fast tracks of China Railway have all been completed and opened to traffic.

By 2018, China was in the Yangtze River Delta.

Pearl River Delta, Bohai Rim.

and other regional urban agglomerations have built a high-density and high-speed railway network, and high-speed rail interconnection has been completed between the four major plate regions of the eastern, central, western and northeastern regions.

On June 17, according to science and technology, by the end of 2020, China's high-speed railway operating mileage reached 10,000 kilometers, ranking first in the world.

There are three stages of China's high-speed rail development:

1. Preparatory stage.

In May 1998, the electrification of Guangzhou-Shenzhen Railway was completed, with a design maximum speed of 200 kilometers per hour, in order to study the feasibility of speeding up to high-speed railway on the existing line of China's railway through tilting trains, in August of the same year, Guangzhou-Shenzhen Railway took the lead in using X2000 tilting high-speed EMUs leased from Sweden.

Due to the adoption of many technologies and equipment that reached the international advanced level in the 1990s, the Guangzhou-Shenzhen Railway was regarded as the beginning of China's transformation from existing lines to high-speed railways. In June 1998, the Shaoshan 8 electric locomotive reached a speed of 240 kilometers per hour in the section test of the Beijing-Guangzhou Railway, which was the first reserve high-speed railway locomotive in China.

2. Transition stage.

The transition to high-speed railways in China began in 1999 with the construction of the Qin-Shenyang Passenger Dedicated Line, with a total length of 404 kilometers, which opened in 2003. The Qinbi-Zaoshen Passenger Dedicated Line is the first passenger dedicated line of China's railways, with a total length of 404 kilometers, which is the starting point of China's railways into high-speed, a milestone construction line of China's railways, and an important part of China's "eight vertical and eight horizontal" high-speed railway network.

In 2002, the self-developed "China Star" electric unit created the "first speed of China's railway" kilometers per hour in the Qinshen passenger dedicated line.

3. The number of fast iron regiments is dead.

January 2004 - The executive meeting discussed and approved in principle the first "medium and long-term railway network planning" in history, and painted more than 10,000 kilometers of "four vertical and four horizontal" fast passenger dedicated line network with great courage. In the same year, China launched the first domestic fast passenger train with a speed of 160 kilometers per hour on the Guangzhou-Shenzhen Railway. The Guangzhou-Shenzhen Railway is known as the "test field" for the growth and maturity of China's high-speed railway.

The development history of China's high-speed rail is as follows:

In the 80s of the 20th century, the Guangzhou-Kowloon Railway Guangzhou-Shenzhen section started the electrification transformation project, and it was planned to introduce pendulum EMU trains to speed up to 160 kilometers per hour, becoming the best test line for the development of quasi-high-speed railways in China.

From 1990 to 1991, China began to plan for high-speed rail technology research and experimental practice, with the Guangzhou-Shenzhen Railway as the pilot line for high-speed transformation, and gave priority to the design of high-speed railways in the Beijing-Tianjin section and Shanghai-Nanjing section of the Beijing-Shanghai Line. The Shenzhen Railway started the quasi-high-speed transformation and became the first quasi-high-speed railway project in China.

In 1996, China and South Korea jointly developed high-speed trains and tested them on the Guangzhou-Shenzhen Railway.

On August 28, 1998, the maximum speed of the Guangzhou-Shenzhen Railway was 200 kilometers per hour, becoming the first railway in China to reach the high-speed target. In December, the Beijing-Shanghai high-speed railway project saw the emergence of two mutually exclusive controversial schemes, "traditional wheel-rail technology" and "maglev track technology", which led to the long-term shelving of the project and once affected the development direction of China's high-speed railway.

On August 16, 1999, the construction of the Qinshen Passenger Dedicated Line started as the first test line of wheel-rail high-speed EMUs in China.

On December 31, 2002, the Shanghai Maglev Train Demonstration Line was completed, with a design speed of 430 kilometers per hour, which is the first high-speed rail system in China.

On October 11, 2003, the whole section of the Qinshen passenger dedicated line was completed and opened to traffic, with a design speed of 250 kilometers per hour, making it the first high-speed national railway line in China.

On June 11, 2005, the construction of the Shitai high-speed railway began, and China officially entered the stage of standardized construction of high-speed passenger dedicated railway.

On January 5, 2007, Taiwan's high-speed railway was put into trial operation, becoming China's first high-speed railway with a design speed of 300 kilometers per hour. On April 18, the sixth large-scale speed increase of China's railways was launched, and the maximum operating speed of some sections of trains was 250 kilometers per hour, and China's railways began to enter the era of high-speed.

On August 1, 2008, the Beijing-Tianjin Intercity Railway was put into operation, becoming the first high-speed railway in Chinese mainland with a design speed of 350 kilometers per hour.

On December 26, 2009, the Wuguang section of the Beijing-Guangzhou high-speed railway was put into operation, with a maximum operating speed of 350 kilometers per hour, breaking the bottleneck of China's railway spring transportation for the first time.

On December 28, 2017, the Shiji high-speed railway was put into operation, and so far, the "four horizontal and four vertical" fast lanes of China's railways have been completed and opened to traffic.

Between 2010 and 2018, China has built high-density high-speed railway networks in urban agglomerations in the Yangtze River Delta, Pearl River Delta and Bohai Rim, and completed high-speed rail interconnection between the four major plate regions in the eastern, central, western and northeastern regions.

On June 17, 2021, according to Science and Technology **, by the end of 2020, China's high-speed railway operating mileage reached 10,000 kilometers, ranking first in the world.

Analysis of the development status of China's high-speed rail EMUs.

The rapid development of high-speed rail has not only significantly improved people's travel conditions, but also driven economic growth and the optimization and upgrading of related industrial structures along the line, promoted the coordinated development of regions and urban and rural areas, and the construction of ecological civilization, resulting in a huge spillover effect. In"Four vertical and four horizontal"After the end, China's high-speed rail construction is still continuing to advance rapidly"Eight vertical and eight horizontal"Forward.

The plan is clear and comprehensive"Four vertical and four horizontal"High-speed railway on the basis of the main skeleton, propulsion"Eight vertical and eight horizontal"The construction of the main corridor, the implementation of a number of high-speed railway projects with passenger flow support, development needs and mature conditions, the construction of a convenient and efficient high-speed railway network, the expansion of service coverage, and the shortening of the time and space distance between regions.

Through the above analysis, it can be seen that countries around the world have a huge demand for high-speed rail, while most countries are still in the initial stage of technical research on high-speed rail, and a large number of high-speed rail imports are inevitably needed. Therefore, from the perspective of demand, the export road of China's high-speed rail is extremely wide, and there is a lot of room for play in the international market.

From the 60s to the end of the 70s of the 20th century, marked by the completion and use of the Japanese Shinkansen railway in 1964, the world began to develop commercial high-speed railways.

From 1990 to 1991, China began to plan for high-speed rail technology research and experimental practice, and proposed the construction concept of building passenger dedicated lines in phases and sections to realize the separation of passengers and freight, taking the Guangzhou-Shenzhen Railway as the pilot line for high-speed transformation, and giving priority to the design of high-speed railways in the Beijing-Tianjin section and Shanghai-Nanjing section of the Beijing-Shanghai line.

By the end of 2019, the total operating mileage of China's high-speed railways reached 10,000 kilometers, ranking first in the world. By the end of 2020, the operating mileage of railways in China was 10,000 kilometers, and the operating mileage of high-speed railways reached 10,000 kilometers, ranking first in the world.

As of 2014, China has the world's advanced high-speed railways, forming a relatively complete high-speed rail technology system; Through the introduction of digestion, absorption and re-innovation development strategy, the system has mastered the manufacturing technology of EMUs with a construction speed of 200 to 250 km/h, and completed the construction of a technical platform for EMUs with a construction speed of 350km/h. The "Design Code for High-speed Railway" was officially released and became the technical standard system for China's high-speed rail construction.

On July 15, 2016, two Chinese standard high-speed EMUs completed a safe rendezvous on the Zhengxu high-speed railway at a speed of 420 kilometers per hour, marking that China has fully mastered the core high-speed rail technology, and at the same time, CRRC Group occupies 69% of the global high-speed rail market and has become the world's high-speed rail leader.

First of all, it has brought more convenience to our travel, especially when we can take the high-speed rail when we go out. Secondly, it can also shorten our journey time and bring more beauty to our lives.

Whether the country's infrastructure is perfect or not can directly determine the country's economic development and people's living standards. Therefore, China's capital investment in the construction of high-speed rail is gradually increasing. Although China is the country with the largest total mileage of high-speed rail, it still needs to build more high-speed railways to meet the accelerated pace of urbanization in China.

China's high-speed rail development process is only a short period of ten years, but we can go from zero to the world's first, and in the past ten years, it has become the country with the largest total mileage of high-speed rail in the world. In this regard, China's high-speed rail can be counted as a world miracle. But China's miracle is completely behind the continuous efforts of many Chinese railway workers, and it took a lot of people's youth to finally reach the world's first level.

The construction of high-speed rail actually has many benefits for a country. First of all, the comprehensive popularization of high-speed rail along the railway line is conducive to people's travel and will bring more convenience to life. After the successful construction of high-speed rail, our means of transportation and travel methods will be changed a lot.

In the past, when we needed to travel farther, we used to take a plane or a bus. The former is too expensive, and the latter is expensive and wastes time, so the emergence of high-speed rail has effectively improved two problems. <>

Secondly, I think the emergence of high-speed rail has also brought a lot of benefits to the logistics and transportation industry to a certain extent. Because high-speed rail transportation is faster and less expensive, it can make the transportation of materials between the two places faster. The cost of economic benefits will usher in a great increase, and the logistics and transportation industry will develop rapidly.
