Constructed by Beyer Peacock of England in 1911, to the DD design of the Victorian Railways. It is similar to exhibit D³635, but with a smaller boiler.

D²604 was sold to Australian Paper Manufacturers in 1956, and was used as a shunter at the Morwell paper mill until the early 1960s.

APM converted it to oil firing, using a tender from a D³ locomotive tender on an underframe from a withdrawn A² locomotive tender.
