RM 4 and RM 6 were scrapped in the 1970s after all re-usable components were stripped from their hulks, while RM 5 and RM 9 were placed into storage at the SSR. With no plans for the SSR to restore either, the decision was made in 1992 to lease RM 5 to the newly formed Pahiatua Railcar Society, who would then restore it to mainline operating standards. The car arrived at Pahiatua in 1992, and work began to slowly restore the car to operable condition.
