Zhang Shuguang, Deputy Chief Engineer and director of the Transport Bureau of the Ministry of Railways (MOR) said on Nov. 6 that it is conceivable that the speed of China's high-speed trains will reach 400 kilometers per hour in next five to 10 years, and the run speed is expected to exceed 500 kilometers per hour in the next 20 years. In the process of optimizing the design, the high-speed railway will save more energy.

Zhang Shuguang said that it is only in less than six years, the running speed of China's high-speed rail increased from 250 kilometers per hour to 350 kilometers per hour and finally to 380 kilometers per hour this year. The 500 kilometers per hour speed test will be made on Beijing-Shanghai section in March next year. It has taken nearly 30 years in the developed countries to complete this process.

Zhang said that the energy-saving effect of high-speed railways is very obvious. The energy consumption of a train with a speed of 350 kilometers per hours is about one-third the energy consumption of a bus, one-sixth of that of a car and one-fourth of that of an aircraft. It also can be more energy efficient by optimizing the aerodynamic shape, reducing running resistance and other technical measures.

China's high-speed train project was first planned in 1992 and was officially launched in 2004. The project adheres to independent innovation and has made significant achievements. Part of the design has been transferred to the United States.

It is understood that developing a higher level of intelligent trains will be one of the Ministry of Science and Technology and Ministry of Railways' key project of the 12th Five-Year Plan and it was included in the national "863 Plan." The intelligent trains will use advanced sensing technology to control the high-speed train's systems and enhance the train's active safety capacity.
