History
In August 1985, Westrail awarded Comeng, Bassendean a contract for five diesel railcars, three ADP cars with driving cabs and two ADQ non-driving cars, using a similar body shell and interior fitout to the New South Wales XPT carriages.[1] Each car was powered by a Cummins KTA19 engine coupled to a Voith transmission. They usually operate as a four car set.[2][3]
In July 2003, the railcars were painted in a new livery in line with the formation of Transwa. In 2007, the railcars were painted white as part of a refurbishment program. In 2010-2011 new seats were fitted.[4]
The railcars were all retired in November 2023 upon the commencement of the Victoria Park-Canning Level Crossing Removal Project and Byford Rail Extension, which suspended the Australind service until June 2026.[5] They were succeeded by ADR/ADS class trains, diesel-powered variants of the Transperth C-series trains.[6][7][8]
One railcar has been donated to Rail Heritage WA, and it is planned to be moved to their museum in Boyanup.[9]
