The standard "full" westighouse freight wagon/car brake has 2 reservoirs, the
auxilary and the emergency. The emergency holds a supply of air in case the
auxilary gets low, it also enables the quick release feature to work by putting
air into the auxilary, thus releaseing the brake whenever an increase in BP
pressure is sensed allowing for a very fast release.

For some reason Australian government railways have stayed with the ancient
system of only one reservoir, the auiliary despite the fact that trains have
gotten longer and heavier.
