These locos were Robe River's main source of motive power until most
were rebuilt as part of the CM40-8M
class. 9424
was bought second-hand from the USA, while 9416 came from Hamersley Iron, and the "new" 9410 came from BHP Port Hedland. As with the same
model
locos at BHP Port Hedland and Hamersley Iron, Comeng took over the
contracts
when Goodwin collapsed.
With the latest Dash-9 arrivals, the last of the class have been
withdrawn,and are stored at Dampier (7-Mile depot).
CM40-8M
Rebuilds:
These locos were the mainstay of Robe River's fleet until recently,
and like their BHP equivalents, are rebuilt from the 1960's/70's
C636/M636 locos. Some also are rebuilt from the C630
class.
However, with the introduction of the latest Dash-9 units, these locos
have now become surplus and were withdrawn in 2004. Nearly all have
recently
been returned to service, due to demand for motive power.
