6029 entered service in 1954 on the Main North line also working on the Main South and later Main Western line. On 17 February 1959 the locomotive was converted to dual control and had an extension to the coal bunker, increasing its coal capacity.[1]
It was restored to operational condition and operated heritage trains for the Canberra Railway Museum. 6029 became the only locomotive of its class to operate interstate when it visited Victoria in 1980, participating in a parallel run to Wangaratta with Victorian Railways locomotive K153.[4] Heritage tours continued over several years until boiler problems caused the locomotive to be withdrawn from service in 1981.[1][5]
In 1994, a feasibility study determined what was needed to get 6029 back in steam.[6] In February 1998, ownership passed to the Canberra Railway Museum.[7]
A replacement boiler was obtained from a Victorian sawmill. Restoration commenced in 2007, being completed in July 2014. After mainline trials, 6029 received official mainline accreditation in December 2014, with the first public trips taking place on 28 February 2015.[1][8][9][10]
Due to the locomotive no longer being based in Canberra, its City of Canberra nameplates were removed in late 2017, and given to two unnamed people.[citation needed] This was due to the locomotive no longer based in Canberra and for historic reasons as the AD60s were barred from travelling though single line tunnels during their service, of which three exist between Bungendore and Queanbeyan on the Bombala railway line.
