China is developing new bullet trains with a speed up to 400 kph, said a leading figure in the countrys high-speed railway technology development.中国铁路技术性发展趋势的一位领军人答复，中国已经产品研发时速达到400千米每小时的新式子弹头列车。Ding Rongjun, an academician of the Chinese Academy of Engineering, said that China was also researching the next generation magnetic-levitation train with a top speed of 600 kph, at a press conference last Monday.中国科学院院士丁荣军上星期一在一场记者招待会上称，中国也在科学研究最少时速约600千米每小时的下一代磁悬浮列车。We are now focusing on how to link TV signals to the trains so that passengers will be able to enjoy films on window-turned screens, Ding said.丁荣军说：“大家如今的关键是如何把卫星信号相接到火车上，那样旅客就可以在窗子的显示屏上喜爱电影了。”A permanent magnet drive system has been added to trains and is undergoing assessment, he said, adding that automatic and unmanned drive technology will be used in the future.他答复，稀土永磁驱动器系统软件早就装货，现阶段已经进行评定。
他补充称作，将来还将用以无人驾驶和自动驾驶技术性。The maximum speed of Chinas bullet trains rose to 350 kph, when the Fuxing (Rejuvenation) bullet trains started operation between Beijing and Shanghai on September 21, 2017.17年1月16，复兴号子弹头列车在上海与北京中间运行时，中国子弹头列车的最少时速降低来到350千米每小时。The Fuxing trains are a substantial upgrade on the previous Hexie (Harmony) bullet trains. Entirely designed and manufactured in China, the Fuxing train is more spacious and energy-efficient, with longer service life and better reliability.复兴号列车是对之前的高铁动车轨道列车的一次全局性升級。复兴号列车基本上是由中国独立设计方案生产制造的，室内空间更为宽敞、更为节约资源、使用寿命更长、可信性高些。
