The first three of 23 Class 7100 25 kV electric locomotives being built for Pacific National by Siemens Mobility's München-Allach plant have entered service in Queensland. The 1 067 mm gauge locomotives were ordered in 2007, and deliveries will run to mid-2010.
Three Class 7100s have three-phase AC traction equipment designed by Siemens, with an output rating of 4 000 kW and maximum speed of 80 km/h. Wheelslip control gives improved performance over the previous locomotives, while ECP braking acts on all wagons simultaneously and can stop a train within 650 m.
