 During their long service lives, many Motor cars had their original fabricated bogies replaced by newer cast-frame bogies; these cast-frame bogies from scrapped Swing Door trains were recycled for use under the Y class diesel locomotives built in the 1960s.Only a handful of cars survived into preservation.A further four carriages, 107M, 12AT, 24D and 137M, were owned by VicTrack and stored at Newport Workshops West Block under the care of Elecrail.
