The brake valves on G543 and the DL ,CLP ,CLF ETC are designated  
30 CDW 
the brake equipment fitted to the NR'S is EPIC electronic 
Although i agree with you wholeheartedly on the wagon equipment it a
joke Westinghouse type W does not even come close to ABDW equipment .
But as we evolve to longer trains (Westinghouse australia admits the
practical limit for type W is 1500 meters)
Apparently NR is looking at the new EP freight system (single wire)
Compatible withe the EPIC brake equipment as well!!
1800 meter trains are on the books!!
Ps the iron ore railways use ABDW equipment and have since day one.
