The '''ADK class''' are a class of [[diesel multiple unit]]s that were previously operated by [[Western Australian Government Railways]] (WAGR) in Perth, and later [[Transdev Auckland]] on [[Auckland]]'s suburban rail network, and are currently operated by [[MetroBus (Mozambique)|MetroBus]] in [[Maputo]], [[Mozambique]]. Originally built by [[Commonwealth Engineering]] and the [[Midland Railway Workshops]] for WAGR in the late 1960s, all but one were sold in 1993 to [[Tranz Rail|New Zealand Rail]], and were then owned by [[Auckland Transport]]. The units were completely withdrawn from service in New Zealand on 5 December 2014, following completion of [[Auckland railway electrification|electrification of Auckland's network]].

==History==

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, New South Wales|Granville]] and railed via [[Melbourne]] and [[Adelaide]] requiring a change of bogies at each of these locations and again at [[Kalgoorlie]].<ref name=GrayMay>{{MayGray-WAGRPassCar |pages=298–303}}</ref><ref name=JDunn>{{cite book|last=Dunn|first=John|title=Comeng: A History of Commonwealth Engineering Volume 3: 1966-19771966–1977|year=2010|publisher=Rosenberg Publishing|___location=Kenthurst|pages=11–15|isbn=9781877058905}}</ref>

Following the electrification of the [[Railways in Perth|Perth]] rail network]], they were rendered surplus and in 1992, all except ADK 689 were sold, along with the newer [[ADL/ADC class diesel multiple unit|ADL/ADC class]], to [[Tranz Rail|New Zealand Rail]] to replace [[NZR 56-foot carriage|56-foot carriages]] on suburban trains in [[Auckland]].<ref name=GrayMay/><ref name=JDunn/>{{sfn|Churchman|Hurst|2001|page=64}}<ref name="nzro1992">{{cite journal|journal=New Zealand Railway Observer|publisher=[[New Zealand Railway and Locomotive Society]]|date=1992|last=Kemp|first=Michael|title=Locomotive notes|page=168|number=212|issn=0028-8624}}</ref>

In October 1993, prior to being privatised, New Zealand Rail sold the class to the [[Auckland Regional Council]] (ARC).<ref>[https://web.archive.org/web/20070530060205/http://www.trainweb.org/nzdiesels/railcar/wrdmu/ ADK/ADL] New Zealand Diesel & Electric Traction</ref>

Line 73:

Unlike the [[ADL/ADC class diesel multiple unit|ADL/ADC class]] and SA sets, the units were not fitted with Electronic Train Protection (ETP) equipment, owing to their imminent replacement by the [[New Zealand AM class electric multiple unit|AM class]]. All are scheduled for withdrawal by late 2014.<ref name=history>{{cite news |title=Railfan|publisher=Triple M Publications|volume=20|number=3|ISSN=1173-2229|date=June 2014}}</ref>

{{As of|2014|9|15}}, all services on the Manukau Line are operated by the [[New Zealand AM class electric multiple unit|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.<ref>{{cite web|url=http://www.gvr.co.nz/Rail+Excursions++Tours/The+Last+Diesel+Subbie+Train+In+Auckland.html|archive-url=https://web.archive.org/web/20151029073655/http://www.gvr.co.nz/Rail+Excursions++Tours/The+Last+Diesel+Subbie+Train+In+Auckland.html|url-status=dead|archive-date=29 October 2015|title=The Last Diesel Subbie Train In Auckland Farewell to the SA's|date=20 September 2015}}{{Dead link|date=June 2022 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> The units were completely withdrawn on 20 July 2015.

== Mozambique ==

In August 2017, eight units were shipped to [[Mozambique]],<ref>{{cite web|url=http://www.scoop.co.nz/stories/AK1708/S00692/aucklands-old-diesel-trains-set-for-new-life-in-mozambique.htm|title=Auckland’s old diesel trains set for new life in Mozambique|date=25 August 2017|access-date=23 March 2020|author=Auckland Council|author-link=Auckland Council|publisher=[[scoop.co.nz]]|archive-date=23 May 2022|archive-url=https://web.archive.org/web/20220523013042/https://www.scoop.co.nz/stories/AK1708/S00692/aucklands-old-diesel-trains-set-for-new-life-in-mozambique.htm|url-status=live}}</ref> with one unit being purchased by the [[New Zealand Special Air Service]]s for training. The shipped units are now running in [[Maputo]], [[Mozambique]], operated by [[MetroBus (Mozambique)|MetroBus]] on a commuter service from [[Maputo Central Railway Station]] to the suburb of [[Matola]].<ref>{{cite web|url=https://clubofmozambique.com/news/metrobus-train-traffic-interrupted-by-floodslandslides-on-rail-tracks/|title=Metrobus Train Traffic interrupted by floods, landslides on rail tracks|date=21 February 2018|access-date=22 February 2021|website=clubofmozambique.com|author=Adrian Fray|publisher=Adrian Fray|archive-date=18 June 2020|archive-url=https://web.archive.org/web/20200618233700/https://clubofmozambique.com/news/metrobus-train-traffic-interrupted-by-floodslandslides-on-rail-tracks/|url-status=live}}</ref><ref>{{cite web|url=https://clubofmozambique.com/news/million-dollar-metro-bus-integrated-transport-project-for-maputo-matola-boane-to-start-operations-soon//|title=Million dollar ‘Metro-Bus’ integrated transport project for Maputo, Matola & Boane to start operations soon|date=5 October 2017|access-date=22 February 2021|website=clubofmozambique.com|author=Adrian Fray|publisher=Adrian Fray|archive-date=13 May 2021|archive-url=https://web.archive.org/web/20210513173435/https://clubofmozambique.com/news/million-dollar-metro-bus-integrated-transport-project-for-maputo-matola-boane-to-start-operations-soon/|url-status=live}}</ref>
