新中国成立以来建设里程最长、投资最大、标准最高的高速铁路——京沪高铁，昨天开始运行试验，为期一个月。6月底，它将正式开通营运。届时，杭州到北京也将实现全程高铁。\n\n从昨天的运行试验来看，京沪高铁最快的一班动车运行时间为4小时48分钟。照此推算，京沪高铁开通后，杭州到北京最快也只要5个半小时多一点（杭州到上海最快45分钟），比杭州到北京现在最快的动车组的运行时间缩短一半。\n\n昨天早上的上海虹桥火车站，出现了很多扛着长枪短炮的记者。他们都为京沪高铁的试运行而来。\n\n昨天上午8点45分，CRH380A动车缓缓从上海虹桥站发出，这是昨天虹桥站开出的第一趟试验高铁，于昨天下午2点15分到达北京。\n\n
