In 1967 and 1968, ten two-carriage stainless steel sets were manufactured for the
Western Australian Government Railways. Each set consisted of an ADK power car manufactured by
Commonwealth Engineering, and an ADB trailer built by the WAGR's
Midland Railway Workshops. The ADK cars were manufactured in
Granville and railed via
Melbourne and
Adelaide requiring a change of bogies at each of these locations and again at
Kalgoorlie. Following the electrification of the
Perth rail network, they were rendered surplus and in 1992, all except ADK 689 were sold, along with the newer
ADL/ADC class, to
New Zealand Rail to replace
56-foot carriages on suburban trains in
Auckland. In October 1993, prior to being privatised, New Zealand Rail sold the class to the
Auckland Regional Council (ARC). In 2004, the ARC funded an upgrade, which included refurbishment of the interiors, painting in the new
MAXX blue colour scheme and mechanical improvements to extend their life by 10 years. After the upgrade, they ran as four-car rather than two-car sets. All were refurbished except ADB 773 (in use at Lock 'n' Load paintball arena) and ADK 689 (which was not exported to New Zealand).
Westrail planned on converting ADK 689 to a self-propelled track inspection carriage but this did not eventuate. Unlike the
ADL/ADC class and SA sets, the units were not fitted with Electronic Train Protection (ETP) equipment, owing to their imminent replacement by the
AM class. All are scheduled for withdrawal by late 2014. , all services on the Manukau Line are operated by the
AM class. As a result of this, all ADK units were placed into storage. Services to Papakura formerly run by ADKs are now run by ADLs, also displaced from the Manukau Line. A farewell trip was run by the
Railway Enthusiasts Society on 16 November 2014, running on every suburban line in Auckland. The units were completely withdrawn on 20 July 2015. == Mozambique ==
