North Island Main Trunk

The North Island Main Trunk (NIMT) is the main railway line in the North Island of New Zealand, linking Wellington, the capital, and Auckland, the largest city, via Paraparaumu, Palmerston North, Taihape, National Park, Taumarunui, Te Kuiti, Hamilton, and Pukekohe.

It is 681 kilometres (423 mi) in length, built to the standard New Zealand rail gauge of 1,067 mm (3 ft 6 in). Most is single track with frequent passing loops, with double track most of the distance between Wellington and Waikanae, and between Hamilton and Auckland. Around 460 kilometres (290 mi) of the line is electrified: 55 km at 1500 V DC between Wellington and Waikanae, and 412 km at 25 kV AC between Palmerston North and Te Rapa in Hamilton. The 34 km between Papakura and Britomart is currently being electrified.

The first section of what became the NIMT opened in 1873 in Auckland. Construction of the Wellington end began in 1885, and the line was completed in 1908 and fully operational by 1909. The line is credited for having been an economic lifeline for the young nation, and for having opened up the centre of the North Island to European settlement and investment. In the early days, a passenger journey along the whole length could take more than 20 hours; today, the Overlander train takes approximately 12 hours.

The NIMT has been described as an "engineering miracle", with numerous engineering feats such as viaducts, tunnels and a spiral built to overcome large local elevation differences with grades suitable for steam engines.

Famous quotes containing the words north, island, main and/or trunk:

    Biography is a very definite region bounded on the north by history, on the south by fiction, on the east by obituary, and on the west by tedium.
    Philip Guedalla (1889–1944)

    Your kind doesn’t just kill men. You murder their spirits, you strangle their last breath of hope and freedom, so that you, the chosen few, can rule your slaves in ease and luxury. You’re a sadist just like the others, Heiser, with no resource but violence and no feeling but fear, the kind you’re feeling now. You’re drowning, Heiser, drowning in the ocean of blood around this barren little island you call the New Order.
    Curtis Siodmak (1902–1988)

    —the main jet
    Struggling aloft unti it seems at rest

    In the act of rising, until
    The very wish of water is reversed,
    Richard Wilbur (b. 1921)

    through the Sumner Tunnel,
    trunk by trunk through its sulphurous walls,
    tile by tile like a men’s urinal,
    slipping through
    like somebody else’s package.
    Anne Sexton (1928–1974)
