 between 1918 and 1962. Although its original design had some key shortcomings, a number of improvements were made over the class' long career on the VR, many of which were subsequently applied to other locomotive classes on the system.

 passenger locomotives. When introduced in 1918, they were the heaviest and most powerful steam locomotives in Australia.

Production

The prototype locomotive C 1 was the last locomotive to be painted in the Victorian Railways 'Canadian Red' scheme. Locomotive C 2 was the first new locomotive finished in the new VR livery of plain, unrelieved black. It was the first of a further 25 C class members also built at Newport Workshops between 1921 and 1926.

Design improvements

In practice, the C class was initially a somewhat less successful design than the A2. Key shortcomings included a very long, 9 in 7 in (2.92 m) manually stoked firebox that was difficult to fire and prone to clinkering, and an undersized boiler. The locomotives tended to run out of steam when worked hard.

In an attempt to rectify these problems, locomotive C 5 was fitted in 1933 with a new front end, based on the Association of American Railroads

, to improve steaming qualities. The results were very promising and led to further experimental work, using A2 class locomotive A2 998 as a test bed and conducted under the direction of VR Rolling Stock branch engineer Edgar Brownbill, in streamlining the steam passages and other changes to reduce back pressure on the exhaust side and increase efficiency. These changes, referred to as 'Modified Front End', were such an improvement that the rest of the A2 and C classes were progressively modified, as well as all of the K

In 1929, C 5 also became the first VR locomotive to be fitted with a cross-compound air compressor, which was also subsequently adopted across other VR locomotive classes. The C class was also the first goods locomotive to be fitted with Automatic Staff Exchange apparatus, given their frequent used on express goods and fruit services.

 exacerbated the problems of firing the C class and industrial action in the mines threatened supply, the entire class was converted to oil firing from 1946 onwards following an initial conversion of C 15 in 1946. Despite the success of the conversion, C class locomotives were still prone to running out of steam when pushed on long rising gradients.

Whereas other VR locomotives to receive Modified Front End treatment had been equipped with smoke deflectors

, increasingly heavy passenger trains and a shortage of suitable motive power saw the C class used as mainline passenger locomotives, a somewhat unusual assignment for a 2-8-0. To facilitate passenger working, their maximum allowable speed was raised from 50 mph (80 km/h) to 60 mph (96 km/h) on the key North Eastern, Ballarat, Bendigo and Geelong lines.

Withdrawal

The postwar rebuilding of Victorian Railways in the late 1940s and early 1950s saw the order of hundreds of new locomotives of superior design to the C class, culminating in the delivery of B class mainline diesel electric and L class mainline electric locomotive

With these new locomotives entering service, the ageing C class locomotives were progressively withdrawn from service, commencing with C 20 in June 1954. The last C class in service, C 7, was withdrawn in April 1962.

Preservation

C 10 was set aside for preservation on 18 May 1962, after having run 1160856 miles (1,868,212 km) during its career on the VR. It is today preserved at the ARHS
