This locomotive was built by Beyer Peacock in Manchester in 1908 as a member of the S636 class.
The first batch of 35 locomotives for the New South Wales Government Railway (NSWGR) entered service in 1903/04. Between 1905 and 1917 Beyer Peacock built a further 60 locomotives and the NSWGR constructed 50 at their Eveleigh Railway Workshop at Redfern in the Sydney suburbs.
The 145 locomotives were reclassified as C30 in 1924. At the same time this locomotive was renumbered from S819 to 3046.
The locomotives were designed to haul the growing traffic on the Sydney suburb services and especially over the heavy gradients on the Northern, Northern Shore and Illawarra lines.
The Sydney railway network was electrified from the mid 1920s which resulted in the locomotives being no longer required to perform the tasks for which they were designed. As the locomotives were regarded as too valuable to scrap 77 locomotives were rebuilt as 4-6-0 locomotives and became the C30T class.
The remaining 68 tank engines, which includes this one, were mostly employed on Sydney suburban to Cowan, Penrith and Campbelltown as well as branches to Carlington, Richmond and Camden. They were also used on suburban services in Newcastle and Wollongong.
A few were redeployed to the country areas where they worked on sections where turntables were not readily available. This included the Casino to Border Loop on the North Coast line, Leeton and Merriwa and shunting at yards such as Bathurst. The daily passenger trains on the extremely steep Unanderra to Moss Vale line were operated by 30 class locomotives until February 1967.
The first locomotive was withdrawn from service in February 1957. By July 1965 only 33 were in service and by mid 1971 only 3 were left in service. The last in service (3085 which is preserved) was withdrawn in February 1973 and was the second last steam locomotive in service on the NSWGR.
This locomotive was withdrawn from service in 1972. It was purchased in 1974 by the Dorrigo Steam Railway & Museum. After a period in store at Rhondda Colliery it was moved to Glenreagh in the mid 1980s and then subsequently to Dirrigo.
The Dorrigo Steam Railway & Museum in Dorrigo is a large, privately owned collection of railway vehicles and equipment. The museum was opened very briefly in 1986 but has not been open to the public ever since. The locomotive is stored at the Dorrigo Steam Railway & Museum.
