The Lalin Railway has been in operation for more than a month, and the Fuxing has run on the roof of the world, bringing happiness to the people of all ethnic groups in Tibet. From construction to operation, there is a science and technology pioneer who has been fighting on the snowy plateau and guarding this new road to heaven.

Facing the harsh environment of high cold and hypoxia, they used their strong will to fulfill their original aspirations and assume their mission; in view of the characteristics of the Lalin railway line, they persevered day and night in the mountains, bridges, tunnels, and inspection vehicles... China Academy of Railway Sciences Group Co., Ltd. The heroes behind the scenes give full play to their roles as leaders, backbones, vanguards, and platforms to provide strong scientific and technological support for the construction and operation of the Lalin Railway.

On July 22, General Secretary Xi Jinping made a special trip to Lalin Railway during his visit to Tibet and gave important instructions. Everyone was very excited and encouraged. They all expressed that they must bear in mind the general secretary Yin Yin’s entrustment, play the key role of scientific and technological innovation, face difficulties, dare to be the first, and make new contributions to the high-quality management and use of the plateau railway. Serving the high-quality development of border areas and the high-quality life of the broad masses of people.

Hold on for several years

The Yarlung Zangbo River, known as the Tianhe River, flows from the icy peaks of the snow-capped mountains and carries the ice liquid jade slurry to the valleys of southern Tibet to nourish flowers and grass. The industrious and kind-hearted Tibetan compatriots work and live here. In order to protect the ecological environment of the snow-covered plateau, the Chinese Academy of Railway Sciences has implemented the concept of environmental protection throughout the entire process of plateau railway construction and operation, and insisted on green planning, green design, green construction, and green operation.

In March 2015, the North China Plain was very cold in spring, and there were few trees on the Qinghai-Tibet Plateau, the third pole of the earth, and the snow covered more than a thousand years. The Lalin Railway Environmental Supervision Project Team of the Chinese Academy of Railway Sciences has already run into Tibet at this time. field.

The Lallin Railway runs along the Yarlung Zangbo River, connecting Lhasa, Shannan, Milin, Nyingchi and other counties and cities. The ecological environment along the line is sensitive and fragile, and the responsibility for ecological protection is heavy.

Chen Zehao, director of the Lalin Railway Environmental Supervision Project Group of the Chinese Academy of Railway Sciences, participated in the construction of the Qinghai-Tibet Railway as early as 2002. At the beginning of 2015, at the age of 50, he once again took the initiative to invite Ying to go to the construction site of the Lalin Railway, which lasted for 6 years.

"The construction of the Qinghai-Tibet Railway has taken the protection of the ecological environment as an important principle that must be followed from the very beginning. The Lalin Railway must also go through green construction to create a fine ‘Tian Road’." Chen Zehao said. In order to actively promote the construction of green projects and environmental protection projects, the project team firmly established the concept of "green water and green mountains are golden mountains and silver mountains", established an ecological environment monitoring index system during the construction period, and collected a lot of data for the ecological environment protection of the Lalin Railway.

Build a beautiful home where man and nature coexist harmoniously. The project team monitors the impact of construction operations on wildlife, engineering barrier effects, utilization of wildlife passages, changes in wildlife populations and individual numbers, and migration routes of wildlife activities in real time, and spares no effort to protect wildlife and restore original vegetation.

Today, Mercedes-Benz's Fuxing will be sprinkled with beautiful scenery along the way. The magnificent canyons, the majestic snow-capped mountains, the blooming Gesang flowers... the beautiful southeastern Tibet has become a new "net celebrity" check-in place, and "traveling Tibet by train" has become a new fashion.

Rise to the challenge

"This is the first time that China has completed the dynamic inspection of passenger and freight railroads at high altitudes above 3,000 meters." said Zuo Zihui, secretary of the party branch and commander of the Lalin Railway Field Command of the Chinese Academy of Railway Sciences. He is less than 40 years old and has led a team to participate in key tasks such as the Chengyu High-speed Railway's quality improvement and compliance operation engineering inspection test, the Zhengxu High-speed Railway high-speed comprehensive test, and the Beijing-Tianjin intercity railway dynamic inspection.

In view of the dynamic detection characteristics of plateau railway lines, the Chinese Academy of Railway Sciences has assembled relevant professional units and invested more than 160 elite forces to test and adjust equipment along the track, catenary, communications, and signals. For the first time, they added passenger car dynamics test items to the dynamic test of general-speed lines, coordinated arrangements for test trains, cargo test trains, signal test trains, and plateau electric dual-source EMU test plans, and researched and designed an adaptable test train marshalling test plan. .

"Rongxiang Yarlung Zangbo River Bridge is the highest bridge I tested." Bridge tester Liang Xiaodong said, "I am very proud to be able to play a role here."

The comprehensive grounding ground measurement points of the Lalin Railway are distributed at Gongga Station, Gongga Yarlung Zangbo River Bridge, and Zanang Traction Substation. In addition, there are 4 short-circuit test points distributed between the Zanang traction substation and the Shannan traction substation. The farthest Zanang traction substation is about 100 kilometers away from Lhasa.

"Every test data on the plateau is not easy to come by, we must ensure that the equipment is in normal condition." Huo Bin, the person in charge of comprehensive grounding, led the staff to leave before 5 o'clock every day to check the equipment before the first inspection vehicle passed the test point. Battery level, sensor status, transmission detection data, etc.

"The left hand holds the box lunch, the right hand holds the data monitoring table" is a colleague's sketch of Yang Wen, the person in charge of passenger transportation service and comprehensive video professional dynamic detection. In order to ensure the physical and mental health of the plateau workers, he led the staff to scientifically arrange the food, clothing, housing and transportation of the team every day, and monitor the changes in everyone's physical data. "I know the blood oxygen, heart rate, and blood pressure of the team members well." Yang Wen said confidently.

On the 400-kilometer Lalin Railway, the dynamic inspection team ran more than 16,000 kilometers with the inspection train, and successfully completed the dynamic inspection task before the opening. At present, the technical personnel of the Fuxing Plateau EMU dispatched by the Chinese Academy of Railway Sciences are still at the Lalin Railway site. They are adding passengers, ensuring the maintenance and troubleshooting in the depot, troubleshooting, and running data tracking analysis to ensure the smooth operation of the trains. Escort.

Not afraid of difficulties

The construction of the plateau railway challenges the limits of the human body. Wherever there is a project, the party branch will be built; wherever there are difficulties, there will be party members charging ahead! Facing the difficult environment of complex geological conditions and high cold and lack of oxygen, the Party Committee of the Chinese Academy of Railway Sciences Group actively reflected the effectiveness of party history learning and education in doing various railway tasks and promoting the high-quality development of railways.

Aspirations do not seek easy, and do not take refuge. The first-line party branch of the plateau inspection accelerates the deep integration of party building and business, launches thematic party day activities at the inspection site, establishes a vanguard of party members, and gives full play to the exemplary vanguard role of party members. They overcame altitude sickness, conducted in-depth analysis and diagnosis of key detection indicators, steadily promoted standardized operation procedures, and resolutely maintained the safety bottom line of the test site.

Leading the development and testing of the two backbone teams of party members of the Fuxing plateau internal electric dual-source power centralized EMU, using innovation as a pen, writes the love of the party and the country on the scroll of overcoming difficulties.

The party member commando team of the Lalin Railway Project headed by Yan Jiulei fully developed the braking system, train network control system and safety monitoring system products, and successfully completed the first application of the integrated comprehensive safety monitoring system in the Fuxing Plateau EMU .

The gold that just won the China Youth May 4th Medal is the commando captain of the main commando team member of the Fuxing Plateau EMU test party. "Party members should take the lead in solving difficult problems, and the difficult environment must be led by party members." From March to June 2021, Gold led his team members to Zhuzhou, Dalian, Nanjing, Beijing and other places as well as China Railway Qinghai-Tibet Group Co., Ltd. For railways and Lalin railways, special tests of complete vehicles are carried out, especially research tests are carried out in the areas of EMU technology improvement, plateau adaptability, internal electric mutual control, and emergency traction of internal combustion power vehicles.

In the many trials, the Tieke people remembered "Being not afraid of the tough, hard work can pass the test" in mind, and used practical actions to compose a hymn to the laborers of the new era. Women do not let the eyebrows. Party member Zhang Jieyu is a PhD in ecology, responsible for the ecological environment monitoring during the construction of the Lalin Railway. When she first set foot on the plateau in 2015, her daughter had just turned 1 year old. Over the past few years, she has turned her love for children and family into great love for the mountains and green waters of the Yarlung Zangbo River basin, and all creatures and creatures. Together with her colleagues, she has submitted a high-quality answer to the environmental protection work of this land.

The rigorous and meticulous work style, the responsibility to take responsibility without fear of difficulties, and the pursuit of scientific research bravely climb the peak are the precious qualities that Tieke people have tempered in the inheritance of the red gene from generation to generation.

In the early days of the founding of the People’s Republic of China, the older generation of Tieke people was full of enthusiasm and devoted themselves to the country, laying the cornerstone for the high-quality development of China’s railway science and technology. Continuing the red blood, continuously drawing on the strength of advancement, and promoting the high-quality development of the enterprise.

The journey starts again, time does not wait for me. As a multi-disciplinary, multi-professional and comprehensive strategic scientific and technological force serving the modern development of China's railways, Tieke people with lofty ideals and full of striving spirit will continue to provide strong scientific and technological support for the high-quality development of railways!
