Train 628 to Napier exits tunnel 1 in the Manawatu Gorge. This photo taken from Highway 3 which is mostly built out on bridge sections from the steep hillside.
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.
