Papakura to Pukekohe Rail Electrification

Under Delivery
Papakura to Pukekohe Rail Electrification

The Papakura to Pukekohe rail electrification project will extend the electric train network approximately 20 kilometres south from Papakura to Pukekohe. Currently Auckland's electric rail network terminates at Papakura, where commuters transfer to diesel trains to reach Pukekohe. The project will also upgrade existing track, signals, level crossings and redevelop Pukekohe Station.

There will be three key changes on the network between Papakura and Pukekohe:

  • Extending the overhead power system from Papakura to Pukekohe
  • Upgrading existing track, signals and level crossings, and
  • Redeveloping Pukekohe Station.

The project is listed as a Rail Development Programme Priority to be completed in the next decade in the Auckland Transport Alignment Project's (ATAP) Recommended Strategic Approach report, released in September 2016.
