It is similar in the way that quick-action happens, but a majordissimilarity is that on freight train brakes (anything from F-27 triple valves to ABDX) all of the air comes through the single brake pipe. The air which eventually winds up in the cylinder under SMEE comes from the local main reservoir. There is a system of orifices and check valves which allows the reservoir to get charged up from either the brake pipe or straight air pipe if the local compressor has failed. |
