During the sidelining of the Chinese built DL locomotives, the DXB fleet made a comeback on many North island trains such as this one from NZ Steel at Mission Bush.
Trains on 3' 6" (1.067m) track from Whangarei to Bluff with virtually heritage rebuilt EMD and GE locomotives still the mainstay power. The network was privatized in 1990's and operated by Toll until 2008 when state owned KiwiRail was established.
