Transforming Auckland’s rail network

Auckland's rail network is being upgraded to enable more frequent and reliable commuter services and to prepare for electrification.

Kiwirail has been working with Auckland Transport to transform Auckland’s rail network. Project DART aims to improve the capacity, reliability and reach of Auckland's rail network. It is now largely completed to a budget of $600 million.

Key components include:

  • Duplication of the western line from Newmarket to Swanson
  • Improvements to Newmarket Station and junction
  • Improved signalling to allow for increased rail services
  • Improved rail links to Manukau City.

Dart 1 - Newmarket Station

This project had a tight budget and timing demands and a need to ensure uninterrupted train services. It was driven by the triple tracking of this section to allow direct through-routing of trains. It is the second busiest rail node in New Zealand. Opus provided architectural, structural, building and design engineering services. The project included two footbridges and a replacement road bridge. The light and airy concourse is the focal space of the station. Newmarket Station received an NZIA Architecture Award.

Dart 2 - Grafton Station

We worked on the preliminary design, then detailed design and technical support during construction of the replacement station. Widening and track duplication has significantly increased train frequency and capacity on the western line.

Dart 9 – Manukau Rail Link

As with Grafton, we worked on the station’s preliminary design and detailed design and technical support during construction. The project won the Concrete Construction Award from NZCS.
