Auckland Transport is upgrading the region’s rail network to meet the increased demand for train travel.
The redevelopment of Auckland’s rail network includes the building of new electric passenger trains (Electronic Multiple Units), station upgrades and electrification works.
Patronage on Auckland’s trains now exceeds 11 million passenger journeys per annum and this growth is forecast to continue. To meet this demand, both regional and central government have made significant investment in rail network improvements.
Auckland's new electric trains are faster, quieter and more energy-efficient.

In preparation for the introduction of new electric trains, KiwiRail has electrified Auckland’s suburban rail network.
Electrification is a vital step towards creating a modern and sustainable passenger transport network. It means quieter and more reliable train services, allowing rail to take a more prominent role in the region’s transport mix.
Electrification will extend from Papakura in the south to Swanson in the west, and includes the Onehunga Branch Line and Manukau Rail Link. Trains are powered from a wire held overhead by masts and cantilevers. The 25kv AC power system (currently used on the North Island Main Trunk between Hamilton and Palmerston North), is used widely overseas and was assessed as the most suitable option for Auckland.
