30 CW in fact. This is what is on the 82 and 90 class. Just as a matter of
interest both operate a B.P. of 500kpa and the 82s use 350kpa max BC (same as
all other NSW locos) where as the 90s use 500kpa in the BC.
As to the rest of the questions I would suggest you talk to the Freightcorp
Brake Engineers.
