Wiri to Quay Park - Third Main

PROJECT STATUS
Under Delivery
Wiri to Quay Park - Third Main

This project involves building a third main line to separate out freight from passenger trains in several locations on Auckland's metro network, including:

  • Westfield and Wiri junctions
  • Middlemore to Wiri, and
  • Quay Park.

The work at Westfield and Wiri junctions will improve how they connect between the rail yards, EMU depot and the main line.

Between Middlemore to Wiri, an additional track will be constructed on the western side. Middlemore Station will also undergo changes, including a new platform and overbridges.

The project will also see the separatiion of freight and commuter trains near Quay Park in the city, so the slower freight trains will not hinder commuter services.

Further, some areas of the rail corridor requires additional land to ensure new rail infrastructure for a third main line can be accomodated. This work is also included as part of the project.
