问题     It is usual to arrange for a delay of a few seconds between the release and the cutting-off of the current and the brake application; this gives the driver the opportunity of crossing quickly to the opposite side of his cab (驾驶室), as he may need to do momentarily for look-out purposes, without stopping his train by so doing.

选项

答案 通常在电流释放和制动切断之间安排延迟几秒钟;这样驾驶员就有机会快速地到达他驾驶室的对面,并有时间完成一些短暂的工作,而且也不用把火车停下来。

解析
