This train of dairy products from the Fonterra milk powder factory at Pahiatua is emerging from the Manawatu Gorge. The highway on the side the photo is taken is permanently closed due to a massive slip limiting the train photography that can be safely achieved. Not that it was that safe when the highway was open.
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.
