UGL/GE ACB Class
The ACB class are six standard C44acis that entered service in 2011 and 2012, slightly more powerful than the earlier Cv43aci-based AC class. Two of them are part of Aurizon's Western Australian standard gauge fleet, while the other four work Hunter Valley coal trains in New South Wales.
