Remarks:     The 'D' class was a variant of the 'C' class saddle tank and was fitted with the same boiler and cylinders of the 'C' but with slightly larger diameter driving wheels. With its leading truck, it was a useful locomotive and more suitable for relatively fast running than the 'C'. They enjoyed a long and active career with NZR, then went on to give good service to private companies at collieries, timber mills and freezing works.
