The railway has been in existence for 200 years. In 1825, the Stockton Darlington Railway was officially opened in England, with trains running at a maximum speed of 24 kilometers per hour; In 2025, China's CR450 high-speed train prototype will once again set a new record for the world's fastest speed of 450 kilometers per hour. The tremendous change spanning 200 years, from a speed of 24 kilometers per hour to 450 kilometers per hour, is exhilarating. At such a special juncture, the 12th World High Speed Railway Conference was held in Beijing from July 8th to 11th. What new trends can be observed through this conference? China's high-speed rail mileage accounts for over 70% of the world's total high-speed rail mileage. Looking at China's high-speed rail, it has achieved a transition from catching up to leading the world. ”At the 12th World High Speed Rail Conference, many people exclaimed, "China's high-speed rail has stood at the center of the world stage. As evidence, 15 years ago, the 7th World High Speed Rail Conference was first held in China, with a high-speed rail mileage of only 7531 kilometers at that time. 15 years later, the World High Speed Rail Conference came to China again. The total operating mileage of high-speed rail in China has reached 48000 kilometers, covering 97% of cities with a population of over 500000 and accounting for more than 70% of the world's total high-speed rail mileage. Over the past 15 years, China's high-speed rail mileage has increased more than fivefold, reshaping the global high-speed rail landscape. Strength speaks for itself - a train sets an international benchmark for high-speed rail technology. Equipped with a permanent magnet traction motor "heart" and wearing an integrated fully wrapped structure "armor", the CR450 high-speed train prototype is undoubtedly the star at this year's World High Speed Rail Conference. As the latest generation of high-speed trains developed in China, the CR450 leads the global trend of high-speed rail: compared with the CR400, the body weight is reduced by about 10%, the running resistance and energy consumption indicators are reduced by 22% and 20% respectively, and the traction efficiency is improved by 4%. The CR450 high-speed train prototype has completed static tests, low-speed tests, high-speed tests, etc., successfully running at a speed of 450 kilometers per hour. ”The relevant person in charge of the Ministry of Science and Information Technology of China Railway Group introduced that starting from August this year, the CR450 high-speed train sample will undergo a one-year 600000 kilometer operation assessment, and can be put into commercial use as early as the end of 2026. A tunnel showcases the hardcore strength of high-speed rail construction. At the mouth of the Yangtze River, an underwater tunnel is being excavated. The Chongtai Yangtze River Tunnel of the Shanghai Chongqing Chengdu high-speed railway along the Yangtze River has a total length of 14.25 kilometers and a designed speed of 350 kilometers per hour. The deepest part of the tunnel is 89 meters away from the surface of the Yangtze River, and is excavated by China's independently developed "Navigation" shield machine. We have equipped the 'Navigation Ship' with a 'Thousand Mile Eye' - a geological advanced prediction instrument. It collects vibration data generated by the cutterhead and rock grinding, and can automatically analyze the geological conditions ahead of the tunnel, making the shield machine more intelligent, efficient, and safe to excavate without stopping. ”Gao Hongbing, General Manager of China Railway Academy of Sciences, said. In the future, the Chongtai Yangtze River Tunnel will become the first Yangtze River tunnel in China to cross the river without slowing down. Looking across the vast land of China, over 100 high-speed railway tunnels with a length of more than 10 kilometers have been built. The Shanghai Suzhou Nantong Yangtze River Highway and Railway Bridge "leaped over a kilometer", and the Fuzhou Xiamen high-speed railway adopts intelligent construction technology to achieve integrated management of the entire process of design, construction, and operation... After years of scientific research and engineering practice, China has built a complete high-speed railway engineering construction technology system. From the ice cities of northern China to tropical islands, from the water towns of Jiangnan to the deserts of northwest China, a group of characteristic high-speed railways that are resistant to high cold, high temperature, drought, and sandstorms have made China the country with the richest high-speed rail operation scenarios in the world. A network reflects the strong strength of coordinated operation. How to fully utilize transportation resources and better meet the travel needs of passengers with a 48000 kilometer high-speed rail network and over 4800 standard multiple unit trains? The secret lies in the train operation diagram. The compilation of train operation diagrams is a very complex task that requires consideration of various types of elements and strong coupling relationships. The combination of different elements increases exponentially with the size of the road network. Taking the Beijing Shanghai high-speed railway as an example, theoretically, the combination scale of all element decision-making can reach over 10 million cubic meters. "said Li Bo, Deputy Director of the China Railway Train Operation Diagram Technology Center. Currently, China has accumulated a large amount of experience in optimizing train operation diagrams for large-scale and complex road network conditions, and is continuously conducting research on intelligent compilation technology to promote the improvement of the quality and efficiency of train operation diagram compilation. The vast network and powerful operational capabilities enable China's high-speed rail to send 16 million passengers in a single day, equivalent to the population of a mega city flowing through the high-speed rail network. In today's China, high-speed rail accounts for about 76% of the railway's passenger volume and 69% of the passenger turnover, equivalent to about 19% of the overall transportation market's passenger volume and 31% of the passenger turnover, becoming the main force in medium and long-distance passenger transportation. Where will the world's high-speed rail go in the future, with faster, greener, and smarter railways? At the 17th China International Modern Railway Technology and Equipment Exhibition, which opened on the same day as the World High Speed Rail Conference, we were able to catch a glimpse. Higher speed - Superconducting electric high-speed maglev vehicle, capable of reaching a speed of up to 600 kilometers per hour. At the equipment exhibition, CRRC brought superconducting electric high-speed maglev vehicles. The so-called superconducting electric high-speed maglev refers to the use of onboard superconducting magnets to interact with coils on the track, thereby achieving contactless operation between the train and the track. At low speeds, the train travels through rubber wheels. After reaching a speed of 150 kilometers per hour, the rubber wheels retract and the train achieves suspended operation. ”Introduction by Shao Nan, Senior Engineer of CRRC Changke Co., Ltd. In addition to superconducting electric high-speed maglev vehicles, the equipment exhibition also showcased conventional high-speed maglev vehicles and conventional medium low speed maglev vehicles. The concentrated exhibition of maglev vehicles is not only a witness to the strength of China's maglev technology from theoretical research to engineering practice, but also demonstrates China's independent innovation capability in the entire industry chain of high-end equipment manufacturing. ”Ding Sansan, Deputy Chief Engineer of CRRC Sifang Co., Ltd., said that in the future, with the iteration and optimization of technology, maglev vehicles are expected to play an important role in the transportation system. Greener - Hydrogen powered high-speed trains enter reality. Last March, the first hydrogen energy city wide train in China successfully completed a full load operation test at a speed of 160 kilometers per hour in Changchun, Jilin. The test results show that the average energy consumption per kilometer of the train is only 5 kilowatt hours, and it can operate safely and stably at temperatures as low as minus 25 degrees Celsius or 35 degrees Celsius. We are working hard to develop a hydrogen powered high-speed train with a speed of 250 kilometers per hour, which is expected to be officially launched by the end of the year. ”Shi Lei, a senior engineer at CRRC Changke Co., Ltd., introduced that with the help of hydrogen energy batteries scattered throughout the roof, the train can achieve a half-hour hydrogen refueling range of 1000 kilometers, zero emissions throughout the entire operation, and wastewater recycling. More intelligent - Artificial intelligence continues to empower the world's high-speed rail. When it comes to the empowerment of high-speed rail by artificial intelligence, many people first think of the Fuxing intelligent high-speed train, which adopts the Beidou satellite navigation system and achieves automatic driving at a speed of 350 kilometers per hour for the first time in the world. In fact, the impact of artificial intelligence on high-speed rail has already penetrated into various aspects. In the field of safety inspection and monitoring, relying on image intelligent recognition technology, the railway "intelligent eye" can accurately identify various safety hazards, defects and diseases; In the field of production operations, underwater facility equipment inspection robots can replace divers for automated testing of bridge underwater foundation piles, reducing work risks; In terms of learning and practical training, the technology of "artificial intelligence+virtual reality" makes the training of high-speed rail drivers more solid... "Although high-speed rail is already a mature technology, innovation cannot stop. Artificial intelligence, 5G communication, seamless transfer, all of these are key to the ongoing railway transformation. ”Francois Dawenna, Director General of the International Union of Railways, said. High speed rail is entering a new stage of global expansion and sharing China's solutions with the world. According to the latest data from the International Railway Union, the global operating mileage of high-speed rail exceeds 65000 kilometers, with more than 10000 high-speed trains running on continents every day. Every year, billions of passengers benefit from this fast, safe, and low-carbon mode of transportation. Today, high-speed rail is entering a new stage of global expansion. ”International Union of Railways President Alain Beloud said that China is a global leader in high-speed rail and an inspiring source of strength. Hand in hand, promote the development of high-speed rail forward. We will continue to improve the coverage and accessibility of the high-speed railway network. ”According to the relevant person in charge of China Railway Group, according to the plan, by the end of 2025, the operating mileage of high-speed rail in China will reach over 50000 kilometers, and the high-speed rail network will cover 97.2% of cities with a population of over 500000; By the end of 2035, the operating mileage of high-speed rail will reach about 70000 kilometers, covering large and medium-sized cities with a population of over 500000 in urban areas, major urban agglomerations, and important economic sectors. Represented by China, high-speed railways are constantly accelerating their development from Europe to India, from North Africa to Southeast Asia, from the Middle East to the Americas. As a leading global manufacturer of rail transit braking systems, the German Knorr Bremse Group has 15 production bases and 4 research and development centers in China. For Knorr Bremse, China is not only a strategic market, but also an important partner for working together to create the future. ”Lang, a member of the executive board of the group, said that we highly appreciate China's continuous expansion of openness and leading the trend on the global stage. Interconnection and sharing opportunities for high-speed rail development. 'Whoosh' (nickname for the Yawan high-speed train) is a high-speed train and also a way of life. ”Deviana Slame Riyadi, Chairman of Indonesia China High Speed Railway Company, said. The Yawan High speed Railway is the first overseas landing of China's high-speed railway system, all elements, and all industry chains. It has transformed the "intercity transportation" between Jakarta and Bandung into "commuting transportation", reducing travel time by nearly two-thirds and sending over 10 million passengers in total. After the completion and opening of the Lao Zhong Railway, the mountains will no longer be high and the roads will no longer be far. ”Vice Chairman of the Lao National Assembly, Songma Ponshina, gave a heartfelt thumbs up. As a member who participated in the planning and construction of the Laos China Railway, Songma Benshena said that the Laos China Railway is not only a strategic channel connecting Laos and China, but also a golden channel connecting Laos with the outside world. As of May this year, the total number of passengers sent on the entire line has exceeded 53 million, and the cross-border transportation volume of goods has exceeded 13 million tons. The Hungary Serbia Railway drives the acceleration of China Europe cooperation towards the future, and the main line project of the China Kyrgyzstan Uzbekistan Railway has entered the substantive construction stage... China Railway adheres to the concept of openness, inclusiveness, mutual benefit and win-win, and promotes the "hard connectivity" of railway infrastructure. Exchange and learn from each other, and share China's achievements with the world.
