Westfield to Whangarei train hauled towards Huirau Tunnel (the 10th of 13 tunnels) by Dc locos 4300 and 4352. This is the only part of the Kiwi Rail network which still has 4 wheel wagons in use (for off-cut logs destined for a wood chip mill near Whangarei.)
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.
