China's high-speed rail brings global partners, cities closer together
China's high-speed rail network spans about 48,000km and connects nearly every city with a population of over 500,000. — China Daily BEIJING: Weeks after the conclusion of the 12th International Union of Railways (UIC) World Congress on High-Speed Rail, industry leaders are still taking stock of China's rapid railway development and its expanding global influence. Held on July 8-11 in Beijing, the congress drew over 2,000 participants from more than 60 countries, regions and international organisations. For many, the event offered first-hand insight into China's achievements and provided a potential roadmap for boosting global connectivity. 'In less than two decades, China has created the largest and most advanced high-speed rail system in the world,' said UIC chairman Alan Beroud. 'It's reshaping mobility, the economy and regional development.' China's high-speed rail network spans about 48,000km and connects nearly every city with a population of over 500,000, which is a 'vital toolkit' for national cohesion and growth, as described by Kevin Smith, editor-in-chief of Britain's International Railway Journal. 'Nobody has done this sort of network expansion in a short period,' said Dennis Noble, an engineer with Queensland Rail in Australia. 'It's very commendable, and something others can look forward to.' Visitors at the congress experienced China's latest trains, including the CR400 Fuxing and the prototype of 450km-per-hour CR450, the world's fastest high-speed train. 'The new trains are modern, faster, better,' said Kaido Zimmermann, general director of Estonian Railways. 'I think it's a central plan to connect the whole country and to promote economic development,' Smith said during his trial run on the CR400. — Xinhua

China unveils next-gen high-speed rail tech as US puts brakes on bullet train funding
China has pulled the wraps off its next-generation high-speed rail technology as the United States revokes federal funding for California's high-speed rail project. Advertisement China's latest bullet train, the CR450 , is undergoing final performance tests to prepare it for commercial operation trials at 400km/h (250mph), the official Science and Technology Daily reported on Monday. The team surpassed the previous upper speed of 350km/h, at which high aerodynamic resistance and energy consumption levels had for decades been a technological barrier. 01:13 China unveils maglev marvel, redefining the future of high-speed rail transport China unveils maglev marvel, redefining the future of high-speed rail transport An increase in speed of 50km/h would lead to a 30 per cent rise in resistance, and greater energy consumption, a researcher at the China Academy of Railway Sciences, Shao Jun, told the newspaper. High-speed trains face 95 per cent of their resistance from air. To boost speed and save energy, the scientists adjusted the head shape of the train to reduce drag, drawing inspiration from nature to create a design based on fast-flying birds and cutting resistance by about 2.6 per cent. They then looked at the train's undercarriage, a previously overlooked area that had potential to reduce drag. Advertisement A team member had proposed an idea for a cover structure to shield the exposed areas of the bogie, creating a more complete aerodynamic shape to lower resistance, Shao said. After repeated optimisation of the cladding structure, resistance was reduced by 22 per cent. This means that even with a 50km/h increase in speed, the energy consumption of the new train remains comparable to that of the CR400 Fuxing trains operating at 350km/h.

Translations may contain inaccuracies—please refer to the original content. China has moved to the testing stage for its next-generation high-speed train, the CR450. Engineers launched a test model from Yichang North Station along the Shanghai-Chongqing-Chengdu high-speed railway, with the train heading toward Wuhan. Newsweek reached out to China's Ministry of Transport via email for comment. Why It Matters China operates the world's most extensive high-speed rail network, with more than 24,855 miles of operational lines, according to a 2023 report from the International Union of Railways. The arrival of the CR450 could further enhance the country's reputation as the world leader in high-speed rail technology, promising faster, safer, and more energy-efficient transportation options. China alone accounts for nearly double the combined length of the rest of the world's high-speed rail systems. What To Know Tests on the CR450 model will continue for around two weeks to validate performance and collect data for system optimization. The CR450 prototype is designed to reach test speeds of up to 450 kilometers per hour (279.6 mph), with an intended operational speed of 400 km/h. Once launched commercially, it will become the world's fastest high-speed train, surpassing China's current CR400 model, which operates at 350 km/h. According to the China State Railway Group, the CR450 will feature a 22 percent reduction in overall operational resistance and a 10 percent decrease in weight compared to its predecessors.

Xinhua The prototypes, which were first unveiled last year, are designed with an eight-car formation comprising four powered and four non-powered carriages, according to train manufacturer CRRC. China's high-speed rail network exceeded 46,000 kilometers by the end of last year. The country added over 3,100 kilometers of new railway in 2024 alone, including 2,457 kilometers of high-speed track, and its overall network now reaches more than 160,000 kilometers. Although it reached test speeds of 450 km/h, authorities stated that the train's operating speed was 400 km/h. According to China Daily, the CR450 has a braking response time of about 1.7 seconds. What People Are Saying Lin Jian, a spokesperson for the Chinese Foreign Ministry, on X, formerly Twitter, in December: "With a test speed of 450 km/h and an operational speed of 400 km/h, it's set to be the fastest high-speed train in the world! Faster, safer, more energy-efficient, more comfortable, and smarter!" What Happens Next The CR450 test phase is expected to last approximately two weeks, with commercial operations of the upgraded rail section scheduled to commence in the second half of 2025.

10 fastest trains of the world are..., first is China's..., its maximum speed is.., India is not in list Trains have been the lifelines for countries for many years. With age and technology, the railway network across the globe has evolved. From a passenger train to a train with new age facility, the railways has come a long way. In this article, we will look at the 10 fastest trains in the world. India with a population of more than 140 billion, Vande Bharat Express has come as boon, which runs at a speed of 180 kmph. At the same time, the rest of the countries of Asia and the world including China, Japan and South Korea have made so much progress that bullet trains running at a speed of up to 460 kilometers per hour have come there.

China testing world's fastest high-speed train prototype at 280 mph pace
China is moving closer to operating what may become the world's fastest high-speed train. According to the Ministry of Transport, the CR450 prototypes have achieved test speeds of 450 kilometers per hour (281 miles per hour) and are expected to run at an operational speed of around 400 kilometers (248.5 miles) per hour. Once commercial service begins, the CR450 could surpass China's CR400 model, which debuted in 2017 and currently runs at 350 kilometers (217 miles) per hour. In a recent CCTV video, the CR450 is shown undergoing comprehensive tests and evaluations. Engineers at the Locomotive and Vehicle Research Institute of the China Academy of Railway Sciences (CARS) have been particularly focused on 'weight control,' ensuring that any reductions in mass do not compromise structural integrity. 'While reducing the weight, we must ensure that its strength does not decrease, and we even need to increase its strength because of the higher speed. It's just like a person who wants to slim down while building strength. This involves structural changes and material innovations,' said Chen Can, an associate researcher at CARS. Sensors have been installed on the tracks to achieve the necessary balance, transmitting real-time weight data from each wheel to a monitoring system. Researchers are also enclosing the entire bogie area beneath the train for the first time to minimize air resistance, a critical factor at very high speeds. 'Ensuring the smoothness of the entire train body minimizes resistance during operation,' said Ha Dalei, a senior designer at the National Engineering Research Center of Rail Transportation at CRRC Changchun Railway Vehicles Co., Ltd. Among the other technical highlights, the CR450 runs on an advanced permanent magnet traction water-cooled system, with an upgraded bogie design for stability. Engineers have also built in more than 4,000 sensors to monitor everything from the car body and pantograph to train control and fire detection systems, along with a multi-level emergency braking system for enhanced safety. The prototypes, CR450AF and CR450BF, each feature an eight-car formation with a mix of powered and non-powered carriages. In addition to the CR400, China already operates other record-breaking trains. The Shanghai Maglev runs on magnetic levitation technology at a maximum speed of about 431 kilometers (268 miles) per hour during regular service. Despite fierce global competition from France's Train à Grande Vitesse (TGV), Japan's Shinkansen, and Spain's AVE Class 103, China is currently the only country operating commercial high-speed rail services at 350 kilometers per hour. The planned 400 kilometers per hour operating speed of the CR450 would reaffirm China's leadership in this arena. Although the CR450 prototypes have passed static and low-speed dynamic tests in traction, braking, and noise control, engineers plan to gradually increase speeds in future trials. The goal is to refine systems for real-world conditions, further cutting vibrations, reducing energy consumption, and lowering noise levels. Once fully approved for commercial operations, the CR450 will not only outpace every other high-speed train worldwide but also make China home to the three fastest trains on the planet.
