Achievements in China’s HSR Development As China HSR is developing rapidly, its high speed railway equipment represented by high-speed EMU become advanced in the world in terms of technology and development thanks to abundant practice in four stages, i.e. independent exploration, introduction and digestion, independent innovation and deepened innovation. Deepened Innovation Independent Innovation Independent Exploration Introduction, Digestion and Absorption Page 3 I. Achievements in China’s HSR Development 1.Largest Operation Scale in the World At present, a high speed railway network of four vertical and four horizontal lines has been build. 86 HSR lines with a total mileage of 22,000 kilometres have been put into service. There are 2,846 sets of high-speed EMUs in operation, with both the operating mileage and train inventory accounting for more than 1/2 of the world’s total.

  • China's High-Speed Trains Are Taking On... Massive Migration
    01/07/2018 China’s high-speed trains are taking on more passengers in Chinese New Year massive migration | Salvatore Babones Unknown date Salvatore Babones China’s high-speed trains are taking on more passengers in Chinese New Year massive migration This Friday is Chinese New Year, the beginning of the Spring Festival and a weeklong national holiday in China. Nearly everyone in China is on the move. China’s transport ministry expects nearly 3 billion individual trips to be made during this year’s chunyun, or “spring rush.” China is still a poor country, and most of those trips (as much as 80%) will likely be made by long-distance bus. But an increasing number of chunyun travelers will be cruising the country in air-conditioned comfort on China’s world-class high-speed rail network. High-speed rail (HSR) in China has ballooned from a single 113 kilometers (70 mile) demonstration line built specially for the 2008 Beijing Olympics into a 25,000 kilometer (15,500 mile) nationwide system. That first Beijing- Tianjin line took three years to build. The rest of the national network took just another ten. China’s originally-planned “4+4” network of four north-south and four east-west main lines is now nearing completion. An extended “8+8” network of 38,000 kilometers (24,000 miles) of high-speed rail is projected to be operational in 2025. Later improvements are likely to focus on speed rather than distance. That said, China does not explicitly define exactly what constitutes “high- speed” rail, and definitive statistics are hard to come by.

Following the analytic process that has been the conducting thread in the last few years, ISOCARP Congresses have been looking at the sustainability problem and how it was and is still affecting the planet from many different professional perspectives. In Dalian, 2008, we looked at urban sprawl, in Porto 2009 we concentrated on Low Carbon Cities in respect of the developed world, in Nairobi 2010, the subject matter focused on sustainability in developing economies. In Wuhan 2011, the overall concept is to attempt to understand how the different alternatives and initiatives can now be blended together with careful attention being paid to all of the policies that have already been discussed in our previous Congresses.

On June 26, the Fuxing Hao with our own IPR made its first departure from Beijing and Shanghai simultaneously. Compared with Hexie Hao, Fuxing Hao has its designed life extended by 50% and can run at a highest speed of 400km/h with lower noise. Moreover, facilities such as sockets, wifi and reading lamps are provided. The emergence of Fuxing Hao marked China’s hi-speed trains being totally made in China from appearance to core technologies. In particular, we managed to develop all the software by ourselves, which symbolized a critical step from chasing to leading for our hi-speed railway development. China’s Achievements in 2017 Mozi quantum satellite seizes commanding heights of quantum science and technology △ Mozi quantum satellite takes the international lead in realizing 1000km-class quantum entanglement distribution On August 10, the Chinese Academy of Sciences (CAS) announced that the Mozi quantum satellite has fulfilled its three major objectives of quantum entanglement distribution, quantum key distribution and quantum teleportation during its one-year stay in space.
