The C30 class (formerly S.636 class) is a class of steam locomotives built by Beyer, Peacock & Company and Eveleigh Railway Workshops for the New South Wales Government Railways (NSWGR) of Australia. ^{[1] [2] [3] [4]}

These 4-6-4 tank locomotives were specifically designed to haul Sydney's ever increasing suburban traffic, particularly over the heavy grades on the Northern, North Shore and Illawarra lines.

Service

The Beyer, Peacock & Company built the first batch of 35 which entered service in 1903/04. Subsequently, between 1905 and 1917, Beyer, Peacock built an additional 60 while the Eveleigh Railway Workshops of the NSWGR built 50 more (3066-3095, 3126-3145). ^[5]

The inner-city lines' electrification made the locomotives obsolete, but they were too valuable to be withdrawn and scrapped at the time. Therefore, from August 1928 to July 1933, Clyde Engineering and Eveleigh Railway Workshops converted 77 of these locomotives to C30T class 4-6-0 tender locomotives to replace older locomotives on country branch lines. ^{[2] [6]}

The remaining unaltered locomotives were primarily utilized on Sydney suburban services to Cowan, Penrith, and Campbelltown, as well as branches to Carlingford, Richmond, and Camden. ^[7] They were also employed on the suburban services in Newcastle and Wollongong. ^[6]

A few drifted to the country areas, working on sections where no turntable was readily available, such as Casino to Border Loop on the North Coast line, Leeton and Merriwa, and shunting at yards such as Bathurst. Until February 1967, these locomotives operated the daily passenger trains on extremely steep Unanderra to Moss Vale line. ^[2]

Following the electrification of the country platforms at Sydney Central station, the 30 class replaced the 26 class locomotives used to shunt carriages in the yard; being not as hazardous to water under the traction wiring. ^[2]

Demise and preservation

The first example was retired in February 1957, and the engine fleet gradually reduced to 33 by July 1965, and further down to only 3 by mid-1971. ^[6] Finally, the last engine, No. 3085, was taken out of service on 22 February 1973, making it the second-last steam locomotive to remain in operation on the NSWGR. ^{[8] [9]}
