This "golden business card" is getting brighter and brighter as it is wiped away!, Xinhua All Media+| China's First Designed High Speed Rail with a Speed of 350 kilometers per hour, 15 Year Old High Speed Rail | Beijing Tianjin | Xinhua All Media+| China

Beijing, July 31 (Xinhua) - On August 1, China's first high-speed railway with a designed speed of 350 kilometers per hour, the Beijing Tianjin Intercity Railway, celebrated its 15th anniversary of operation. This "starting point" marks a new chapter in the development of China's high-speed rail. After the Beijing Tianjin intercity railway, a large number of high-speed railways have been built, put into operation, and China has gradually formed a world advanced high-speed railway technology system with independent intellectual property rights, creating a Chinese high-speed railway brand with world-class operational quality. The "golden business card" of China's high-speed railways is getting brighter and brighter.

Over the past 15 years, the Beijing Tianjin intercity railway has witnessed an important development process of China's high-speed rail industry

The Beijing Tianjin Intercity Railway is an important component of the intercity passenger transportation system in the Bohai Rim region, which is planned for the medium to long term railway network. It is also the first high-speed railway in China with a designed speed of 350 kilometers per hour.

On August 1, 2008, the Beijing Tianjin intercity railway was opened, and the renovated Beijing South Station and Tianjin Station were officially put into use on this day. A fast and comfortable rail transit mode was established between the two major cities of Beijing and Tianjin. After the coordinated development strategy of Beijing Tianjin Hebei was proposed, the Beijing Tianjin intercity railway was extended to Yujiapu Station in Binhai New Area, and passengers can arrive at Binhai within 1 hour from Beijing at the fastest.

With the increase of passenger flow, the Beijing Tianjin intercity railway is gradually transitioning towards public transportation, with the shortest departure interval shortened from 15 minutes to 3 minutes. According to statistics from China Railway Beijing Group Co., Ltd., in the past 15 years, the Beijing Tianjin intercity railway has transported a total of 340 million passengers.

The changes between Beijing and Tianjin are a microcosm of China's high-speed rail development. As of June 2022, China has nearly 3200 kilometers of high-speed rail with a normalized speed of 350 kilometers per hour; As of the end of 2022, the operating mileage of high-speed rail is 42000 kilometers, ranking first in the world.

The Story Behind It

When a train is running on a railway line at a speed of 350 kilometers per hour, a small bump can cause an accident. Therefore, maintenance of high-speed rail lines is crucial. In 2013, China Railway Beijing Group Co., Ltd. established the Beijing High speed Railway Engineering Section, which is currently responsible for the maintenance of over 1500 kilometers of high-speed railway lines, including the Beijing Tianjin Intercity Railway.

"The operation of high-speed rail is greatly affected by the natural environment, and civil defense, physical defense, and technical defense are effective means of monitoring." Xu Leigang, Deputy Director of the Safety Production Dispatch Command Center of Beijing High speed Rail Engineering Section, said that the engineering section uses various technical means on and off the train to monitor important factors and key links such as wind, rain, roadbed, and tunnel mouth within the scope of high-speed rail operation in real time. All big data is summarized and analyzed daily to guide maintenance work.

From "350" to "453", independent innovation continuously refreshes the "Chinese speed"

High speed rail is a successful example of independent innovation in China. After years of scientific research and engineering practice, China has built a complete high-speed railway technology system, with the overall technical level entering the world's advanced ranks, and some fields reaching the world's leading level. The "Fuxing" high-speed train has taken a crucial step from catching up to leading the way.

In 2018, all Beijing Tianjin intercity trains were replaced with the "Fuxing" China Standard Multiple Unit trains. Subsequently, the Beijing Tianjin intercity railway was normalized to operate at a speed of 350 kilometers per hour.

Supported by independent innovation, the "Chinese speed" is still refreshing. Recently, China Railway Group organized performance verification tests on new technology components of high-speed trains under higher operating speed conditions. The test trains reached a maximum operating speed of 453 kilometers per hour, marking new progress in the development of the new generation of CR450 high-speed trains.

Based on technological innovation, China has built the world's largest and most modernized high-speed railway network, forming a world advanced high-speed railway technology system with independent intellectual property rights, and creating a Chinese high-speed railway brand.

In recent years, the Beijing Zhangjiakou high-speed railway has achieved commercial operation of autonomous driving at a speed of 350 kilometers per hour for the first time in the world. The high-speed maglev transportation system with a speed of 600 kilometers per hour, the variable gauge high-speed EMU with a speed of 400 kilometers per hour, and the high-speed freight EMU with a speed of 350 kilometers per hour have successfully been offline.

The Story Behind It

The intelligent dispatch and command system provides strong support for precise passenger service and efficient production organization.

"In high-speed rail maintenance, we have developed a centimeter level high-precision positioning railway operation personal safety protection system based on the Beidou." The relevant person in charge of the Beijing Communication Section said that employees only need to wear a Beidou positioning terminal the size of a "matchbox" to achieve "civil defense vehicle" and "vehicle defense person" warning functions based on the train position.

The fast and convenient high-speed rail has compressed the distance between time and space, making it a reality to return thousands of miles of Jiangling in a day. "Sitting on the high-speed rail to see China" has become a popular way of traveling for many people.

Kang Shunxing, the director of the ticketing workshop at Beijing South Station, who will retire this year, remembers that when Beijing South Station was put back into operation, it was both big and imposing. However, colleagues felt that such a large station may take several years to "recover", and they didn't expect it to be "fully booked" on the day it opened. From an average of 20000 passengers per day to 170000 passengers per day, Beijing South Station has sent a total of 451 million passengers in the past 15 years.

China is willing to share the achievements of high-speed rail development with the world

Although China's high-speed rail development is later than that of developed countries, after several generations of railway workers continue to strive, the overall technical level has entered the world's advanced ranks, and we are willing to share the achievements of development with the world.

Since the first international passenger train was launched on April 13, 2023, the China Laos Railway has sent 33000 cross-border passengers by June 30.

The Hungary Serbia Railway is a landmark project of cooperation between China and Central and Eastern European countries. The section of the Hungary Serbia Railway from Belgrade to Novisad in Serbia was opened for operation on March 19, 2022.

The Yawan high-speed railway is the first high-speed railway in Indonesia and Southeast Asia, and also the first overseas construction project of China's high-speed railway with a full system, all elements, and all industry chains. It is designed with a speed of 350 kilometers per hour and adopts Chinese technology and standards for the entire line.

The Story Behind It

The China Laos Railway starts from Kunming, China in the north and ends in Vientiane, Laos in the south. During the summer transportation, fruits from Southeast Asian countries arrive in Kunming every day through the China Laos railway.

The Yawan high-speed railway has entered the preparatory stage before its opening. After official operation, the travel time from Jakarta to Bandung will be significantly reduced, improving local transportation conditions and driving economic and social development along the route.

China's high-speed rail has gone global, paving the way for happiness for local people's lives and providing acceleration for regional development.
