As an employee of China Railway Engineering Group Co., Ltd., I feel extremely proud when the speeding train carries passengers along the crisscross railway lines to the distance. Long dragons made of steel stretch across the land of China, reposing the dreams of my colleagues and I. The change of railway reflects the high-quality development. On the territory of the motherland, the railway line running through the north and South and connecting the East and the West has woven a railway network, which provides important support for people's travel and economic development. In recent years, I have followed the steps of major project construction of the group, traveled across the north and south of the motherland, and successively participated in the construction of Beijing Zhangjiakou high-speed railway, Lalin railway and other projects. Seeing the railway paved, the highway connected, and the bridge erected, the once insurmountable natural moat has become a thoroughfare. At the moment of the completion of the project and the opening to traffic, my colleagues and I always have thousands of feelings in our hearts and are proud of the development of our motherland. Every project is the fruit of hard work. During the construction of Xiaoxiangling tunnel of Xincheng Kunming railway, colleagues worked for more than 10 hours a day, and ate in the tunnel. All the time saved was used for construction. This is the longest line and the most difficult construction project in the new Chengdu Kunming railway. With the perseverance of daring to fight and fight, colleagues have refreshed the record of tunnel mechanized drilling and blasting construction time and again. After the completion of this railway, the time from Chengdu to Kunming will be greatly shortened, and the people of Daliang Mountain in Sichuan can also get a "free ride" and embark on the "expressway" to happiness. There is a lot of energy and a few brushes. In the construction of major projects, we should not only work hard, but also tackle key problems in scientific research and improve the scientific and technological content of project construction. To build the railway to Lhasa, we must first solve the problem of frozen soil on the plateau. In order to overcome this worldwide problem, Northwest Research Institute of China Railway Research Institute has built the world's only year-round observation station of plateau frozen soil on the wind volcano at an altitude of 4780 meters. Over the past decades, generations of scientific and technological workers have adhered here, accumulated more than 12 million data covering various meteorological conditions and ground temperature changes in the plateau permafrost areas, condensed into dozens of major scientific and technological achievements, and provided precious scientific support for the construction and operation of the Qinghai Tibet railway. Bravely climb the new peak of Railway Science and technology, generations of China railway builders have shown their responsibility and responsibility with the ambition of innovation. The power of spirit is infinite. We often say that where there are difficulties, we can go. After the Wenchuan earthquake in 2008, a large area of mountains collapsed above tunnel 109 of Baoji Chengdu line, of which 12 oil tankers loaded with 500 tons of aviation gasoline caught fire. It is urgent to put out the fire and resume traffic. China Railway Electrification Bureau quickly gathered the rescue team and risked their lives to "go retrograde". In times of crisis, they showed their heroism. After 12 days and nights of rescue and fierce battle, the artery from northwest to southwest was opened, and a lifeline of earthquake relief was also opened. So far, we still remember the sonorous oath of "fighting for the lives and property of the people, for the supreme interests of the country and society, and for the smoothness of the lifeline in the disaster areas". Only with the spirit of fearing difficulties, risks, youth and blood can we condense the powerful force of bravery and entrepreneurship. Success comes at a time of prosperity, and struggle is at the right time. The youth imprint of generations of CREC people has been engraved in the mountains, plains, deserts and Gobi. The CREC people in the new era should work hard and tirelessly to strive for good results belonging to our generation.
