Pacific National will use the locomotives for shunting operations at the BlueScope steelworks at Port Kembla in New South Wales and it expects to receive the remaining five units over the next few months.

The four-axle locomotives have a nominal power rating of 1.19MW, derived from two Cummins QSK19 engines and share the same gensets, control system and other critical key components with NREC's six-axle 1200 class demonstrators which were delivered to Australia in May 2013.
