3900 Class - Electric
<-Back
QR decided that the last 30 locos from Clyde/Walkers would be used for passenger and general freight work, rather than export coal, and thus these locos became the 3900 class. That have a higher speed, and work passenger trains between Brisbane and Rockhampton and Emerald. As well, they haul general freight between Brisbane and Rockhampton, in the Brisbane area, and some grain from Emerald. All are based in Brisbane. More recently, some have been used on Bowen Basin coal traffic, being replaced by Diesel locos on mainline work.
