DXB 5108 (GE U26C) leads DFT 7239 on a milk train from Palmerston North to Whareroa near the Rangitikei River at Kakariki. At nearby Marton this train will take the Marton-New Plymouth Line which abounds in 1 in 35 grades.
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.
