1550/2400 Class - Diesel Electric
<-BACK
The 1550 and 2400 classes now work typically on general freight traffic around Queensland, along with passenger services. Some of these locos were used in the Bowen Basin prior to electrification, with the 2400, 2450, and 2470 classes seeing work at the Blackwater, Gregory, and Curragh mines respectively. Some of the 1550 class were also used for the Phosphate Hill phosphate mine. Most of the class are based in the central or northern regions of the state. Several of the locos have been rebuilt as the 2300 class, and there will be 60 in all rebuilt.
