K 900 was donated to MOTAT, and prior to being delivered to the MOTAT site, it was put on display outside Sims Pacific Metals until 1975 when it was replaced by DF 1301. It was then transported to the main MOTAT site and placed at the Rail Pavilion in the company of AB 832, F 180 "Meg Merrilies", J 1236, WW 491, and diesel-electric locomotive DA 1400. It has remained on display at MOTAT since then, initially in the open but later under a shelter roof.
