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 The units were completely withdrawn from service on 5 December 2014, following completion of [[Auckland railway electrification|electrification of Auckland's network]].
