A few years later, in 1997, the port area returned, the port area officially became an indivisible part of China, and China's railway also entered the port area by the time, that year is the year of national celebration, but also a sign that the Chinese territory must be unified, the following year China's most glorious heavy weapon symbol, "high-speed railway" began a long career, in the middle of the month, the electrification of the Guangzhou-Shenzhen railway was completed, the design of the maximum speed of 200 kilometers per hour,

In order to study the feasibility of speeding up to high-speed railways on the existing lines of China's railways 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 use of many technologies and equipment that reached the international advanced level in the 1990s,

Therefore, at that time, the Guangzhou-Shenzhen Railway was regarded as the beginning of China's transformation from existing lines to high-speed railways and 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, setting a record of "the first speed of China's railway" at that time, and was the first reserve high-speed railway locomotive in China.

In 1999, the construction of the Qin-Shenyang passenger dedicated line was opened in 2003, with a total length of 404 kilometers, and the first passenger dedicated line of China's railway was born, with a total length of 404 kilometers, which marks that China's railway has entered the high-speed, which is a milestone construction line of China's railway, and is also an important part of China's "eight vertical and eight horizontal" high-speed railway network. In the middle of 2002, China's self-developed "China Star" electric unit created the "first speed of China's railway" at that time in the Qinshen passenger dedicated line 321.5 km / h.

In January 2004, the executive meeting of the State Council discussed and approved in principle the first "Medium and Long-term Railway Network Plan" in history, and painted more than 12,000 kilometers of "four vertical and four horizontal" fast passenger dedicated line network with great boldness. 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.

From 2004 to 2005, CNR Changchun Bus Co., Ltd., Tangshan Bus Company, and CSR Qingdao Sifang introduced technology to design and produce high-speed EMUs.

On April 18, 2007, the sixth major speed increase of China Railway and the new train timetable were implemented, and the rapid railway reached 6,003 kilometers and CRH EMUs were adopted. Speed-up sections of busy trunk lines reach speeds of 200 to 250 km/h. This is the highest speed increase of existing railway lines in the world.

In 2004, the introduction and innovation of high-speed railway construction started by the fourth large-scale railway speed increase in China, and nine core technologies were conquered and high-speed rail conditions were explored.

On February 26, 2008, the Ministry of Railways and the Ministry of Science and Technology of China signed a plan to jointly develop and operate a new generation of high-speed trains with a speed of 380 kilometers per hour.

On August 1, 2008, China's first world-class high-speed railway with completely independent intellectual property rights and a speed of 350 kilometers per hour, the Beijing-Tianjin Intercity Railway was put into operation.

On December 26, 2009, the Wuhan-Guangzhou high-speed railway, which has the longest mileage and the most complex project type in the world, with a speed of 350 kilometers per hour, was put into operation.

On February 6, 2010, the world's first Zhengxi high-speed railway, built in a collapsible loess area and connecting central and western China at a speed of 350 kilometers per hour, was put into operation.

On December 1, 2012, the world's first high-speed rail line located in the alpine region Harbin-Dalian high-speed railway was officially opened to traffic, 921 kilometers of high-speed rail, connecting the major cities of the three northeastern provinces as a line, from Harbin to Dalian in winter only 4 hours and 40 minutes. The Harbin-Dalian high-speed railway will run at the "Chinese speed" of 200 kilometers per hour in winter in the alpine region, becoming a beautiful scenery.

By the end of 2012, the total length of China's high-speed railways reached 9,356 kilometers. Since 2013, with the successive opening of the Nanjing-Hangzhou, Hangzhou-Ningbo, Panying high-speed railways and the Xiangpu railway, the new operating mileage of high-speed railways has reached 1,107 kilometers, and the total mileage of China's high-speed railways has reached 12,000 kilometers.

On November 25, 2014, CNR CRH5A EMUs, which are equipped with the "Created in China" traction electric drive system and network control system, entered the final stage of the "5,000 km positive line test".

This is the first high-speed EMU in China to realize the complete independent innovation of traction electric drive system and network control system, marking the transformation of the core technology of China's high-speed rail trains from "localization" to "independence", and the leap from "Made in China" to "Created in China" for China's high-speed rail trains. It will vigorously enhance the core creative capacity of China's high-speed rail trains and consolidate the confidence of China's high-speed rail to go global.

On April 3, 2014, the fully autonomous CNR CRH5 EMU traction electric drive system passed the industry expert review organized by China Railway Corporation.

On October 22, 2014, the fully autonomous CNR CRH5 EMU train network control system ("Brain of High-speed Rail") passed the technical review organized by China Railway Corporation and was approved for batch loading, becoming the first EMU train network control system approved for batch loading and operation in China. Subsequently, the CRH5A EMU equipped with CNR's autonomous traction system carried out a positive line test at the Harbin Railway Bureau.

In 2014, the scale of new railway lines put into operation in China reached a record high, and the operating mileage of railways exceeded 112,000 kilometers. The operating mileage of high-speed railways exceeds 16,000 kilometers, ranking first in the world. The construction of railways in the central and western regions has set off a climax, with an operating mileage of 80,000 kilometers, accounting for 62.3% of the total operating mileage of railways in the country.

Summary: On August 1, 2008, China's first high-speed railway with independent intellectual property rights and international level "Beijing-Tianjin Intercity Railway" was officially put into operation. Subsequently, the Beijing-Guangzhou high-speed railway, the Zhengxi high-speed railway, the Shanghai-Nanjing high-speed railway, the Shanghai-Hangzhou high-speed railway, the Beijing-Shanghai high-speed railway and other high-speed railways have been completed and opened to traffic.

In recent years, China's high-speed rail has become a benchmark for China's latest technology to enter overseas. China's high-speed rail is making great progress overseas, and with its cost-effective and successful operation experience, it has won orders in the global market one after another. According to data, CRRC's business volume has ranked first in the world in the railway equipment industry and rail transit equipment industry, and China's high-speed rail accounts for about 30% of the global market share.

At 11 o'clock on November 25, 2015, the leaders of the state and the leaders of 16 Central and Eastern European countries boarded the high-speed train from Suzhou to Shanghai.

At 8:30 a.m. on July 15, 2016, representing the latest achievement of China's standard EMU test task, a Chinese standard EMU train departed from Zhengzhou East Railway Station and started a new "test run". At 11:19, two EMUs rendezvous at a speed of 420 kilometers per hour in Minquan County, Shangqiu, Henan Province, Zhengxu High-speed Railway, and a new world record for the speed of the intersection of EMUs was born.

The comprehensive test of the Chinese standard EMU on the Zhengxu high-speed railway has successfully obtained the operating energy consumption data, vibration and noise characteristics of the Chinese standard EMU, and explored the change law of key technical parameters of the high-speed railway system with a speed of 400 kilometers per hour and above, which provides strong technical support for deepening the theoretical research on the wheel-rail relationship, pantograph-network relationship and aerodynamics of China's high-speed railway, as well as the core technology research and operation management of high-speed railway.

On September 10, 2016, the Zhengzhou-Xuzhou high-speed railway, which connects the Beijing-Guangzhou high-speed railway and the Beijing-Shanghai high-speed railway, with a design speed of 350 kilometers per hour, was put into operation.

On March 5, 2018, the operating mileage of high-speed railways increased from more than 9,000 kilometers to 25,000 kilometers, accounting for two-thirds of the world's total, the mileage of expressways increased from 96,000 kilometers to 136,000 kilometers, 1.27 million kilometers of rural roads were newly built and reconstructed, 46 new civil aviation airports were built, and the world's largest mobile broadband network was built.

On June 7, 2018, China Railway Corporation launched the field test of high-speed EMU automatic driving system (CTCS3+ATO train control system) on the Beijing-Shenyang high-speed railway, which marks that China Railway has achieved important stage results in the independent innovation of key core technologies of intelligent high-speed rail, and the overall technology of China's high-speed rail continues to lead the world.

By the end of 2018, China's high-speed rail mileage exceeded 29,000 kilometers, accounting for more than two-thirds of the world's high-speed rail mileage and more than other countries combined. In 2019, it is planned to ensure that 3,200 kilometers of new high-speed rail lines will be put into operation. As of April 2019, the length of China's high-speed rail bridges exceeded 16,000 kilometers, and 20 years ago, China's high-speed railways were left far behind by many countries.

In the past 20 years, from scratch, from there to refinement, the wisdom and tenacity of the Chinese have been fully reflected in the high-speed rail industry, China's high-speed rail self-contained system is unsurpassed by the world, and what does it mean behind the brilliant high-speed rail career? The brilliant high-speed rail industry represents not only the transportation force, but also the embodiment of a country's comprehensive strength, the level of science and technology, as well as the attitude of Chinese railway people and the spirit of hard work, China's high-speed rail is the miracle of the world, but also the pride of China.

As early as 2010, the Road Bureau organized a retired cadres to visit the high-speed rail stations, Li Tieguo was more than seventy that year, but these years under the care of Xu Fangling, his body is very tough, but in the end he still uses crutches, and on the day of going to the major high-speed rail stations, Li Tieguo and his old buddy Zheng Duoyu went together, that day they were both wearing a driver's uniform issued by the Road Bureau in the early years, the style is a bit like a tunic like that, gray and black, and the brim of the hat with a large brim on the top of the head is a little curled.

In their hands, one of them also carried a toolbox, and after entering the bullet train section, Li Tieguo joked with Zheng Duoyu with a smile, and also took out a hammer from the toolbox, saying that he took Zheng Duoyu to drive the train for several years, and now he has to teach him how to overhaul the locomotive, the way he spoke was exactly the same as Wu Laosan, not serious, but after the two of them walked into the maintenance workshop in the high-speed rail section together, Li Tieguo looked at the huge mechanical arm and the complex assembly line in the factory in front of him, he smiled, The hand was released, and the hammer slowly smashed on the concrete floor,
