Data from Howell, Comparative Statistics of the Australasian Railways, Journal of the Royal Statistical Society, March 1899, pp. 96-97 and locomotive diagram hosted by [], last accessed 6 September 2008. The diagram is labeled "1937 (Second Hand)", but the data fit between the two sources is pretty close with the diagram preferred because of its completeness.
When it went into service, the C class was intended for mixed traffic on light lines. Light indeed - notice the axle loading of less than 7 long tons.
In 1912, the TGR modified six of these engine to CC standard, which meant new boiler with Belpaire firebox to serve larger cylinders. Four more Cs went through the modification program in 1924; these also exchanged their Stephenson valve gear for Walschaert.
The Tasmanian Transport Museum's C22 amassed 882,188 miles (1,411,500 km) during its career from 1902 to October 1960. It has been restored to working order twice since retirement, once in 1983 for a period of 16 years until boiler repairs forced its withdrawal and 2008 after repairs were completed.
