美国铁路近年来提出一种新的高效率“整体列车”的概念,即由自带动力的遥控列车组组成的列车,它可独立运行。车辆之间,机车与车辆之间连接的牵引装置是无间隙的,运行中没有或很少有冲动作用。由于机车外端的车钩是可以遥控操作的全自动车钩,来自不同始发站的列车组可在编组站组成一列长列车。因此,编组作业可遥控进行,极为简单,也不需 In recent years, the U.S. railroad has proposed a new concept of an efficient “monoblock train,” a train of self-powered remote train units that operates independently. Traction devices connected between the vehicles and between the locomotive and the vehicle have no gaps, and there is little or no impulse in operation. Since the coupler at the outer end of the locomotive is an automatic coupler that can be operated remotely, trains from different origin stations can form a long train at the marshalling station. Therefore, grouping operations can be remotely controlled, extremely simple and not required
