History

In August 1985, Westrail awarded Comeng, Bassendean a contract for five diesel railcars, three ADP carriages with driving cabs and two ADQ trailer carriages, using a similar body shell and interior fitout to the New South Wales XPT carriages.[1] Each carriage was powered by a Cummins KTA19 engine coupled to a Voith transmission. They usually operate as a four carriage 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]

They are scheduled to be replaced by six Alstom built railcars in 2022.[5][6]
