The ADL class is a class of diesel multiple units operated by Transdev Auckland on the suburban rail network in Auckland, New Zealand. Originally built in the early 1980s by A Goninan & Co for Westrail of Western Australia, they were sold in 1993 by Westrail's successor, Transperth, to Tranz Rail. The units are currently owned by Auckland Transport.

History

Between 1982 and 1985, ten two-carriage stainless steel sets were manufactured for Transperth by A Goninan & Co, Newcastle.

Refurbished ADL 802 at Westfield in October 2005

Following the electrification of the Perth rail network they were rendered surplus and in 1993 all were sold, along with the older ADK/ADB class, to New Zealand Rail to replace 56-foot carriages on suburban trains in Auckland.[1] In October 1993, prior to being privatised, New Zealand Rail sold the class to the Auckland Regional Council.[2]

In 2002, the Auckland Regional Council funded an upgrade of the class, which included refurbishment of the interiors and painting in the new MAXX blue colour scheme. The first refurbished unit entered service in December 2002, the last in November 2003.

In 2011, Auckland Transport indicated four two-car sets would be retained after the Auckland rail electrification project is completed.[3]

Since November 2013 the units have been fitted with Electronic Train Protection (ETP) equipment, and two seats in each car next to the passenger door closest to the driver's cab have been replaced by an equipment rack.

Due to the introduction of the AM class on the Onehunga Line and Eastern Line, the ADL class units are now only used on the Southern Line and the Western Line.
