Description

The Q Class was introduced onto the Westrail SG network in 1997/98. 19 were built to the Clyde/EDI-EMD GT46C design, and a further 4 nearly identical units went to Freightlink for the Darwin line (FQ01-04) and one (V544) for V/Line-Freight Australia. The units for Westrail were built at three plants: Bassendean, WA; Somerton, Vic and Kelso, NSW.

They are powered by an EMD 16-710G3B-ES engine rated at 4200 flywheel bhp and supplying 4000hp (2980kW) into the EMD AR-11 CA7 alternator for traction. Six DC traction motors of model EMD D87BTRL are fitted.

They were originally numbered Q301-319. ARG renumbered them Q4001-4019. Q class locomotives are among those fitted for DPU operations on 159-car ore trains between Koolyanobbing and Esperance.

Max speed: 115km/h
