Final scrapping of the 12 remaining units (14 D and 11 DM cars) began at Hutt Workshops just after 18 December 2012, starting with a mix of DM and D cars, before in January concentrating on the D class trailers and followed by the DM power cars. It was announced on 23 January that the three-car DM 556 "Cyclops" set was put aside for the Wellington Heritage Multiple Unit Preservation Trust, while the two-car DM 216 "Phoenix" set was put aside for preservation by the National Railway Museum of New Zealand. Trailer D 2826 was also put aside to be moved to Belgrove to join DM 562 and D 2419, converting it to an impromptu three-car set in the same way as the original three-car D/DM/D sets.
