BHP Billiton Iron Ore once ran Australia's highest horse power locomotives in the form of the General Electric AC6000CW model.
Incorporating a GE-Deutz design 6000 horsepower 7HDL16 prime mover with a displacement of 175 litres and AC traction.
These units far out perform the older 4000 horsepower Dash 8 locomotives, and this was the only place that these 6000hp units could be found outside the USA.
All eight locos reused the names originally applied to the Dash 7 fleet, which the AC6000 replaced and were:
6070 - 51062 - Port Hedland.
6071 - 51063 - Chichester.
6072 - 51064 - Hesta.
6073 - 51065 - Fortescue.
6074 - 51066 - Kalgan.
6075 - 51067 - Newman.
6076 - 51068 - Mount Goldsworthy.
6077 - 51069 - Nimingarra.
Livery, serial number and build info for each unit can be found here BHP Power Roster Page.
6076 was the first AC6000 to be repainted in the new bubble scheme in September 2003.
6075 was repainted in October 2007, 6073 in March 2008 and 6070 in June 2008. The rest of the fleet wore the BHP blue scheme until scrapped.
All these units were re-engined during overhaul with the new 6250 hp GEVO-16 prime mover.
This was carried out to trial the engine prior to GE producing 6250 hp Evolution Series ES59ACi units for China.
Following a derailment at Turner Siding in late May 2011 class leader 6070 was written off due to extensive damage.
In October 2014 the remaining seven units along with the remaining SD40 units were scrapped at Sell & Parker's yard in Wedgefield, WA.
