And you - general megathread poster - yeah - just in case you accidentally wander into the news megathread one day, there are some things you should know, and one of them is that there is absolutely no evidence to support the statement that we're the greatest megathread in the world.

We're seventh in citations, twenty-seventh in accurate predictions, twenty-second in effortposts, forty-ninth in non-mainstream article posting, 178th in guessing when wars will start, third in powerusers, number four in dialectics, and number four in megathread exports. We lead Hexbear in only three categories: pointless infighting, number of adults who believe Putin is based, and copium manufacturing, where we produce more than the next twenty-six lemmy megathreads combined, twenty-five of whom are full of delusional liberals. None of this is the fault of any Hexbear user, but you, nonetheless, are without a doubt, a member of the WORST-period-GENERATION-period-EVER-period, so when you ask what makes us the greatest megathread in the world, I don't know what the fuck you're talking about! Jokes about whether they got a Zionist's semen in time?!

Alexander Mercouris, who does daily videos on the conflict. While he is a reactionary and surrounds himself with likeminded people, his daily update videos are relatively brainworm-free and good if you don't want to follow Russian telegram channels to get news. He also co-hosts The Duran, which is more explicitly conservative, racist, sexist, transphobic, anti-communist, etc when guests are invited on, but is just about tolerable when it's just the two of them if you want a little more analysis.

    China's CR450: A new era of high-speed rail at 400 km/h

    Article

    The CR450 high-speed train prototype, unveiled in Beijing on Sunday, is capable of reaching a test speed of 450 km/h and an operational speed of 400 km/h. This achievement makes it the fastest high-speed train in the world once it enters commercial service, surpassing China's current CR400, which operates at 350 km/h.

    According to China State Railway Group, which led the development, the CR450 excels in key areas such as operational speed, energy efficiency, noise control, and braking performance, setting new global benchmarks. Despite its higher speed, the CR450 maintains braking distances similar to those of trains running at 350 km/h—thanks to significant engineering advancements. These design enhancements ensure the train's stability, performance, and safety at higher speeds.

    The CR450 prioritizes passenger comfort, offering a smooth and quiet ride even at 400 km/h. Advanced noise-reduction technologies ensure that interior noise levels are comparable to those of 350 km/h trains, providing a peaceful travel experience.

    A standout feature of the CR450 is its exceptional energy efficiency. The train has reduced running resistance by 22 percent and cut its weight by 10 percent, improving fuel efficiency. Despite the increased speed, these optimizations minimize energy consumption, ensuring sustainability at higher operational speeds.

    The train's interior has been redesigned for added comfort and convenience, increasing cabin space by 4 percent. Adjustable luggage racks and a versatile storage area accommodate passenger needs, including bicycles, wheelchairs, and other items. These innovations anticipate potential regulatory changes in passenger transport.

    The CR450 prototype was developed by CRRC Changchun Railway Vehicles and CRRC Sifang Co., Ltd., each contributing slightly different interior designs but with a shared focus on passenger comfort and high-quality travel experiences.

    The development of the CR450 is the culmination of years of research and technological innovation, which began in 2018 with the goal of operating trains at 400 km/h. Extensive testing has been conducted across major high-speed rail lines, including Zhengzhou-Wanzhou, Jinan-Zhengzhou, Mile-Mengzi, and Fuzhou-Xiamen. Over 200 days of high-speed testing and 17 component trials have been completed, with a cumulative test distance exceeding 200,000 kilometers. The prototype has undergone more than 3,000 simulations and over 2,000 platform tests to meet the rigorous demands of 400 km/h operations.

    China State Railway Group has announced that further line tests and refinements will ensure the train meets all necessary standards for commercial operation. The goal is to make this cutting-edge technology available to passengers soon.

    Li Yongheng, an official from China State Railway Group, stated that since 2012, China's railway sector has independently developed a series of scientific and technological innovation products, exemplified by the Fuxing high-speed electrical multiple unit (EMU). This development has established a comprehensive high-speed rail (HSR) technology system encompassing engineering construction, equipment manufacturing, and operations management.

    "China's high-speed railway system has taken a historic leap, shifting from a follower to a global leader. Its HSR technology has set an international benchmark," Li said.

    "To further consolidate and boost China's leading edge in HSR technology, and better serve and support Chinese modernization, our company, along with relevant ministries, organizations, research institutes, universities, and enterprises, has formed an innovative team to tackle key technological challenges," he added.

    Zhao Hongwei, chief researcher at the China Academy of Railway Sciences, highlighted the technological breakthroughs of the CR450 EMU, including advancements in high-speed safety, resistance reduction, energy efficiency, vibration and noise reduction, and intelligent fusion control technologies. These innovations have established a comprehensive technical framework for the 400 km/h high-speed train, setting a new standard in global rail transport.

    Wang Wenjing, a professor at the School of Mechanical, Electrical and Control Engineering at Beijing Jiaotong University, discussed the challenge of achieving a lightweight design that balances speed and energy efficiency. The BJTU team focused on optimizing load-bearing components, especially the bogie and car body, through simulations and bench tests. Advanced materials like carbon fiber were incorporated to reduce weight while maintaining strength, ensuring safety and durability at high speeds.

    Sui Fusheng, a researcher at the Institute of Acoustics at the Chinese Academy of Sciences, emphasized the complexity of balancing weight reduction with noise control. The team developed integrated composite materials that provide both thermal insulation and soundproofing. These innovations reduce material costs and complexity while improving passenger comfort by controlling temperature and noise levels. Despite the challenges, the team's solutions have set the stage for quieter, more efficient high-speed rail travel.

    The CR450 EMU exemplifies China's innovation-driven development strategy and demonstrates the country's scientific and technological capabilities. It reflects the advantages of China's socialist system, fostering self-reliance in railway science and technology and contributing to the modernization of the railway industrial system.

    Over the past 15 years, China has built the world's largest and most advanced high-speed rail network, spanning over 160,000 kilometers, including more than 46,000 kilometers of high-speed rail lines.

      Some technical commentary I have with less rigorous sources:

      This train once operational will hit 250mph in regular service, the fastest steel wheeled train in service in the world. 250mph is seriously pushing what steel wheels on steel rails can do, but I have no doubt that China Railways is up to the task, considering that they have been running trains at 217mph (350 km/h) for several years now, and have successfully exported the technology to Indonesia for the Whoosh (yes, that's the official name!). To my knowledge there are no other countries that run trains in service as fast as China or Indonesia, although Spain and South Korea are probably the closest.

      Anecdotally Japanese train twitter seems to be taking note. Japan's Shinkansen, while excellent, has been falling behind in recent years. There is a maglev under construction that will beat the service speed of the CR450, but that's years off. For now, the Shinkansen tops out at 320km/h, and the most popular route only hits 285km/h top speed.

      When it comes to speedy trains, infrastructure and infrastructure maintenance matter much more than the train itself. The current record for conventional trains (i.e. not maglev) is 574.8 km/h (357 mph) which was set by a TGV in 2007. However, the trains that use that track only hit 320km/h in revenue service. This is because super fast trains can really damage the rails and other infrastructure over time. The ballast was probably retamped and the power grid was not built for those kinds of speeds. Chinese high speed rail, however, is built to higher standards. For example, the Beijing-Shanghai high speed railway was designed for 380km/h but in practice these speeds have never been reached in service. Hopefully these new trains help them achieve that goal.

      I also hope and expect China to go for the steel wheeled record. CRH puts the TGV to shame, time to take that record from them too.
