These units were originally built for the Transperth division of Western Australian Government Railways in 1967-68. The ADK driving units were manufactured by Commonwealth Engineering and the ADB trailer units were manufactured by Westrail.[1]

They were purchased along with the newer ADL class units by New Zealand Rail Limited in 1993 to replace suburban carriage trains then used in Auckland. Later that year, they were sold by NZR to the Auckland Regional Council. The units were credited with an increase in patronage in the Auckland system, but have a number of reliability problems due to their age[2].

In 2004 the ARC funded the upgrade of the entire class, which included refurbishment of the interiors of the units and the painting of the exterior in the new MAXX colour scheme. The upgrade also include mechanical improvements which would extend the useful life of these units by 10 years. After the upgrade most ADK trains will run as permament 4-cars sets rather than 2-cars previously.[3]
