“复兴号”在京沪高铁实现350公里时速运营 提速后北京到上海只要四个半小时

2017-09-21 18:02:05   国际在线

国际在线报道(记者 李琳):从21日起,中国“复兴号”高速列车开始以350公里的时速,在京沪高铁线上投入运营,这也将北京到上海全程运行的时间从五个多小时缩短到4个半小时左右。至此,中国也成为世界上高铁商业运营速度最高的国家。

21日早上九点,G1次“复兴号”动车组列车从北京南站始出,前往上海虹桥站。列车开行大约18分钟后,车上的显示屏显示:列车的时速达到了350公里。在乘坐这趟车的旅客看来,列车此时依旧非常平稳。

“只是看提示的时候看到(列车时速达到350公里),身体没什么感觉,还是蛮舒服的,听平稳的。”

“坦白说挺平稳的,如果没看显示屏的话,我都不知道是300还是350。”

从21日开始,京沪高铁上的“复兴号”动车组列车开始按照350公里时速运营。而过去,中国的高铁运营时速最高只有300公里。目前京沪高铁日均运行400多列车,其中有七对是“复兴号”,而这次七对“复兴号”全部提速。

中国铁道科学研究院首席工程师赵红卫认为,“复兴号”在京沪高铁上按照350公里时速运营,不仅可以缩短旅客的旅行时间,也可以使中国的高铁积累更多的运营管理经验,为下一步的发展奠定基础:“我们按照时速350公里运营,一方面可以缩短旅客的运行时间,增加同城的效应,同时能够利用既有的资源,提质增效,能够最大的发挥经济效益。从技术方面可以积累更多的运营管理经验,为以后不管是研制速度更高的动车,还是其他的不同速度级的动车组有更多技术和经验储备。”

值得一提的是,经过这次的提速,中国成为世界上高铁商业运营速度最高的国家。中国铁路总公司运输局副局长黄欣表示:“首先标志着中国高铁为世界高铁的商业运营树立了一个最高时速的新标杆,同时也为适应铁路供给侧结构性改革,满足广大旅客对于不同速度等级的高铁的需求。今天的正式运营,也标志着全面的中国标准,最高的中国速度,将为中国高铁走出去,奠定扎实的基础。”

对于中国高铁的发展,安全性和速度一样备受关注。赵红卫说,无论是京沪高铁还是“复兴号”动车组列车,运营的安全性是有保证的:“这个线路(京沪高铁)在当初建设的时候就是按照350公里设计的,它也是一次建成,历程最长,技术标准最高,技术也是最先进的,我们的路基、桥梁隧道一直是保持了一个最好的工作状态;第二个方面,我们在列车控制、牵引供电、基础设施等各个方面也得到了加强;装备采用复兴号,技术水平也得到了突破,运用调度水平也提高了,所以在运营上是保证的。”

中国铁路总公司总经理特别技术顾问、中国工程院院士何华武曾表示,今后,随着“复兴号”下线数量和人们出行需求增加,提速的列车数量将会逐步增加。不过他也强调,中国的各条铁路要根据不同的出行需求、不同地区的经济条件综合考虑,确定开行什么样的时速是比较合适的。
