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.
