　　In the rainforest infested with snakes and insects, he carried out "carpet-style" surveys and promoted China's high-speed rail to win the first overseas order; in the face of boring data, he tackled the "stuck neck" problem and promoted the full set of technologies of the high-speed rail train control system to achieve independent control... …They are "the most beautiful railway people", they are upright and innovative, they work hard, and they are constantly struggling on the new journey.

Dare to take responsibility and promote China's high-speed rail to win the first overseas order

　　On November 16, 2022, on the verdant island of Java, Indonesia, the Jakarta-Bandung high-speed rail was successfully put into trial operation.

Witnessing the historical moment, Xia Jian, the executive deputy manager of the Jakarta-Bandung high-speed rail project department in Indonesia and the overall design director of China Railway Design Group Co., Ltd., was excited. Confidence and confidence in the 'Belt and Road Initiative'."

　　The location of the Jakarta-Bandung high-speed railway is covered with tropical rainforest, which is inaccessible and infested with snakes and insects.

In order to find the way, the designers had to wear masks, wield sticks, carry 20 kilograms of equipment, and endure the scorching heat to carry out "carpet-like" surveys in the rainforest.

After one month, Xia Jian led the team to walk more than 300 kilometers on foot. The detailed geological survey laid a solid foundation for the high-quality design.

　　The bidding for the Jakarta-Bandung high-speed rail project was fiercely competitive.

Xia Jian led the team to fight all night, combined with Indonesia's national conditions and the needs of the owners, carried out in-depth research on technical solutions comparison and selection, technical standard adaptability, business model, investment and financing model, human resource training, etc.

The more than 400-page feasibility study report fully demonstrates the all-round technical advantages of China's high-speed rail in terms of economy, safety, and comfort.

In the end, Xia Jian led the team to win the first overseas order of China's high-speed rail, realizing the first overseas landing of China's high-speed rail technical standards.

　　In May 2020, due to the spread of the global epidemic, the construction of the Jakarta-Bandung high-speed rail project suffered serious setbacks.

At that time, the new crown vaccine had not yet been released, but Xia Jian, who was already on vacation in China, offered to return to the Indonesian project site immediately: "The project needs me, and the comrades on site need me." On the first day of resumption of navigation, Xia Jian led 8 colleagues , spanned three countries and four places, and returned to the Jakarta-Bandung high-speed rail project department after more than 30 hours.

Focusing on epidemic prevention with one hand and production with the other, he ran to the site and construction site during the day, changed drawings and held online meetings at night, and seized the day and night.

Under the influence of Xia Jian, a group of technical backbones born in the 1985s and 1990s grew rapidly, and combined with Indonesian geology to launch a number of innovative breakthroughs, proving that there is no technical obstacle for China's high-speed rail to go to the world.

Be good at tackling difficulties, and promote the complete set of technologies of high-speed rail train control system to achieve independent control

　　High-speed rail going global is inseparable from the independent innovation of high-speed rail core technology and equipment.

The train operation control system, known as the "central nervous system" of high-speed rail, is the key to ensuring the safety and efficiency of high-speed rail operation.

　　Successfully developed a high-performance DS6-80 safety computer platform with completely independent intellectual property rights, enabling the high-speed rail train control technology to achieve a leap from being imported from overseas to being exported to Europe.

The R&D leader who achieved this leap is none other than Liu Zhen, Director of the Basic Equipment Technology Research Institute of CRSC Research and Design Institute Group.

　　More than 10 years ago, the security computer platforms used in the high-speed rail train control system were all imported from abroad, and the main technology was monopolized by several European signal companies, so it was difficult for China to upgrade the system independently.

　　"The real core technology cannot be bought, and we must develop our own products." Liu Zhenyong took the heavy responsibility.

In 2012, CRSC launched the independent research project of CTCS-3 train control system.

In the next three years, aiming at each pass and keeping an eye on each short board, Liu Zhen led the team to complete all the development and industrialization of the underlying hardware and software of the high-performance DS6-80 security computer platform, and launched the core computer for the first time in China. Vehicle MVB communication chip, transponder chip, "Anda" safety operating system and many other achievements with independent intellectual property rights.

The "stuck neck" problem was easily solved, and the complete set of technologies of China's high-speed rail CTCS-3 train control system realized independent control.

　　Successful research and development is only the first step, and the autonomous train control system still needs to undergo application tests.

China's high-speed railways operate at high speeds, have long mileage, and have complex application environments, which pose great challenges to the reliable operation of train control systems.

Zheng Xiaoyan, deputy director of the electrical maintenance technology center of the Zhengzhou high-speed rail infrastructure section of China Railway Zhengzhou Bureau Group Co., Ltd., is responsible for the functional verification of the high-speed rail train control system.

　　"It is necessary to ensure that the interlocking relationship is 100% correct and the train control data is 100% correct, in order to ensure the safety of passengers' lives and property." In the signaling machinery room at a corner of Zhengzhou East Railway Station, Zheng Xiaoyan walked through a thick signal equipment technical atlas. Between the combined racks full of relays, check the direction of the rear wiring of each relay and the wiring on the side of each combined rack one by one.

　　Zheng Xiaoyan relies on tenacity and meticulousness to find problems and solve problems from the data every day.

Before the joint commissioning and testing of the Zhengzhou-Xuzhou High-speed Railway, Zheng Xiaoyan led her colleagues to verify more than 300,000 data seven times, completed the tests of 28 train control centers and 4 speed-limiting servers, found and solved 127 problems, and ensured that Zheng The Xuzhou High-speed Railway successfully connected to Zhengzhou East Railway Station.

　　"We are all like tightrope walkers. We have to be cautious and cautious every time we verify. With the formation of the "m" shaped high-speed railway in Henan, the train control inspection team has also grown." For more than ten years, Zheng Xiaoyan has successively presided over Zheng Yu and Zheng Fu , Shanghe-Hangzhou, Jizheng and other new high-speed railway train control system construction construction and joint commissioning and joint test work, compiled a number of regulations and guidance books, provided important reference for standardizing professional management, and cultivated professional technology for the national high-speed railway train control system There are 1080 person-times of talents.

He said: "I have caught up with the good times, and I must seize the opportunity to educate people for the party and the country."

Diligent research, let the train run safely on the vast land

　　"Learning EMU maintenance technology, I always maintain a 'hunger'." Dong Hongtao, EMU mechanic at the EMU Technology Center of Xi'an EMU Section of China Railway Xi'an Bureau Group Co., Ltd., actively devoted himself to the railway industry after being demobilized from the army in 1992.

In 2007, the railway speed was increased for the sixth time. At the age of nearly 40, he applied to be the first batch of on-board mechanics of EMUs on the national railways.

　　In order to deal with "new friends", Dong Hongtao spent almost all his time studying the structure and components of the EMU.

One notebook after another is filled with learning theory, drawing, drilling trenches, climbing on the roof, maintenance limits, fault phenomena, and processing procedures.

Colleagues joked: "Dong Hongtao can point out the location of each component with his eyes closed, and he can tell where the problem is by listening to the sound."

　　Dong Hongtao is not only good at troubleshooting, but also good at eliminating hidden dangers.

He led a team to develop special tooling for quickly unblocking toilet blockages in CRH380B EMUs, so that toilet blockages in EMUs can also be disposed of on the way, reducing the phenomenon of locked toilets in passenger-carrying EMUs; The operation time was reduced to less than 15 minutes; he developed a special tool for automatic exhaust of the CRH2 EMU tread cleaner, which reduced the number of operators by 2/3...

　　In the more than 10 years of working on EMUs, Dong Hongtao has led an innovative team to carry out scientific and technological research. He has successively guided and dealt with more than 1,000 large and small faults, innovated and transformed 26 practical tooling, obtained 22 national patents, and trained more than 100 young business backbones. Eliminate safety hazards with your own hands, and let the EMUs run safely on the vast land, no matter how hard or tired you are, you will be willing."

　　In Shantou, Guangdong, there is also a repairman who has practiced eighteen kinds of martial arts.

At the Shantou Locomotive Depot of China Railway Guangzhou Bureau Group Co., Ltd., whenever encountering "difficult and miscellaneous diseases" of diesel locomotives, everyone will say in unison: "Look for Brother Jiu!"

　　Brother Jiu, Ru Dejiu, the foreman of the maintenance workshop, has overhauled more than 15,000 locomotives in the past 20 years, with high quality and high efficiency.

　　In order to improve the maintenance efficiency of the "heart" of diesel locomotives, he got into the waste warehouse of the workshop to study for 3 months, and innovatively developed a "special rapid measurement sample gauge", which shortened the measurement operation time from 30 minutes to 5 minutes, which attracted the attention of surrounding enterprises. Come for advice.

In order to quickly solve the locomotive failure, even during weekend breaks, he quickly rushed to the maintenance depot, got into a small space that can only accommodate one person to work, and "operated" with a flashlight in his mouth for nearly 3 hours. In the end, he was too tired to lift his arms. Get up... Over the years, Ru Dejiu led the team to obtain 16 various innovative inventions, among which 3 achievements, such as the double installation groove adjustment ring gear of the diesel locomotive fuel injection pump, won national patents, saving more than 10 million yuan for the unit.

　　Someone asked Ru Dejiu: "Is it worth the effort?"

　　Ru Dejiu always said with a smile: "Let the driver drive well and the passengers sit safely. I will contribute to the transportation power of the country, and it is worth it."
