Emergency-Applicatioti Position. When it is desired to makethe shortest possible stop, the brake-valve handle is i)laced in emer-gency position, as illustrated in Fig. 24. In this position the brakepipe is opened directly to the atmosphere through the large port /,cavity c, and port A*, causing a sudden and rapid drop in brake-pipepressure. In this position, cavity p in the rotary valve connects. Fig. 25.
