问题 通常在减压，切断电流和制动之间有几秒钟的间隔，这就使得司机能够迅速跨到驾驶室的另一边，因为他可能需要做瞬间的嘹望，这样做他就不需要把火车停下。
选项
答案 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 to cross quickly to the opposite side of his cab, as he may need to do momentarily for look-out purposes, without stopping his train by so doing.
