The CBH class is a class of diesel-electric freight locomotives designed and manufactured in the United States by MotivePower in Boise, Idaho, for Western Australian grain growers' co-operative CBH Group.
The CBH class was ordered to haul grain trains on the open access rail network in the south of Western Australia. The trains, operated for CBH by Aurizon under a long-term contract, link various CBH grain collection points in the wheatbelt with CBH terminal and port facilities in Albany, Geraldton and Kwinana.
The 25 members of the CBH class are divided into three sub-classes, based on differences in power output, traction motors and track gauge.
