In 1911 the WAGR placed an order with the North British Locomotive Company for twenty 4-6-4T locomotives to haul suburban passenger services in Perth. All entered service between June and September 1912. Commencing in 1932, all bar D386 were rebuilt as the Ds class with superheated boilers. In 1935, D377 was fitted with larger side tanks increasing its water capacity by 210 gallons, these were removed in May 1959. With the arrival of the ADH class diesel multiple units in 1953, withdrawals commenced with the last withdrawn in November 1965.[2][3]
The D class was also the basis for the later Dm and Dd classes of tank engine, which continued this role until the end of steam.
The numbers and periods in service of each member of the D class were as follows:
