it was re-certified for mainline running again and made its debut back on the main line in spectacular fashion with a doubleheader from Glenbrook to Hamilton with JA 1271. After a further two years of mainline running Diana retired to the GVR for the remainder of her boiler ticket, on Auckland Anniversary Weekend in 2017 a Farewell Weekend was held for the engine and she operated for a further 4 months before her last day in service on 30 April 2017. The locomotive is now under an overhaul. JA 1260 was preserved by the Ashburton Railway and Preservation Society in May 1972. It saw limited use on the Plains Railway's line before a year's lease to the Weka Pass Railway in 1986. After its return to Plains, it was dismantled for an overhaul which was protracted due to other pressing projects. In 2007 work on this locomotive began at a fast pace, and in May 2008 JA 1260 was back in service on the railway. Notably, JA 1260 is the only preserved member of the class to be operating at a lower boiler pressure of 180psi instead of 200psi – this reduction was made due to the limited nature of operations at The Plains Vintage Railway & Historical Museum. JA 1267 was preserved by a syndicate and stored at the Te Awamutu Railway Museum at Te Awamutu, 1972. It sat on static display under a rudimentary shelter until 2008 when due to the winding up of the museum and discord amongst the syndicate, the locomotive was placed up for auction. It was purchased by Ian Welch and transferred to the Mainline Steam Heritage Trust's Parnell depot where it is stored pending eventual overhaul to mainline running. JA 1271 was preserved by Reid McNaught and Russell Gibbard in 1978. At the time of purchase JA 1271 was incomplete and in a sorry state, having been used as a stationary boiler plant since 1970 after a motion failure. It was transferred to Steam Incorporated's Paekakariki base and comprehensively restored to mainline running. Its debut in 1997 kicked off with a tour of the South Island, before returning north where it has become a very active mainline locomotive. It hauled the 2003 50th Anniversary Commemoration train of the Tangiwai disaster, and also was used prominently in the 100th Anniversary of the Parliamentary Special. JA 1274 was preserved by the New Zealand Railway and
