“动车组”不同于传统列车靠火车头在前方牵引,而是把带牵引动力的动车与没有牵引动力的拖车,按照一定的参数组合在一起,形成两端都可以驾驶、时速200公里以上的高速旅客列车单元,其最大特点是牵引力大,编组灵活,制动效率高,且调速性能好,即使其中一节牵引动力源发生 Unlike the traditional train locomotive traction in front of the traction, but with the traction power of the motor car and no traction power of the trailer, according to certain parameters together to form both ends can drive at speeds above 200 km Of the high-speed passenger train unit, which is the most prominent feature of traction, flexible group, high braking efficiency, and speed performance, even if one of the traction power source occurs
