Dd Class Locos

The 4-6-0 type Dd-class was the first of seven standard steam locomotives designed by Victorian Railways engineers in the early decades of the 20th century. Intended as a mixed traffic locomotive primarily for use on the light branchlines, it proved a successful and highly versatile engine with 261 built by the government workshops and private contractors between 1902 and 1920.

Later improvements included the provision of superheaters from 1914 and larger boilers from 1922. When the planned electrification of the Melbourne suburban system was delayed, a modified 4-6-2 tank engine version (known as the DDE-class) was developed to haul larger suburban passenger trains, with some 58 built between 1908 and 1913.
