A tank version of the C class 2-6-4 locomotive, Wf393 was built at the Thames, New Zealand works of A&G Price Ltd. in 1904. A total of 41 of this class were constructed both by the New Zealand Government Railways workshops and by Price mainly for suburban services. This class was also used on the isolated Nelson-Glenhope line and during World War II a number were sold to Tasmanian Railways.
Throughout their long life these locomotives worked on most parts of the NZR system, and proved a very versatile engine. Wf393 was withdrawn from service in 1967, and donated by the Minister of Railways at that time to the Canterbury Branch of the New Zealand Railway and Locomotive Society. The locomotive has been stored since arrival and is now displayed in the Steam Shed at Ferrymead.
