It was announced in 2013 that K 911 will be the next major restoration project at Mainline Steam's Wellington depot at Plimmerton. K 911 retained its cylinders and was noted shortly after purchase in 1998 at their temporary Gracefield depot as having been stripped down for an overhaul. This was put on hold prior to the move to Plimmerton, at which point the boiler was lowered back onto the overhauled frames for storage. Some of its parts were borrowed for use on KA 942, then under restoration at the Glenbrook Vintage Railway in South Auckland.
