Kapiti Line

KiwiRail and Greater Wellington Regional Council are working together on Future Rail, a programme to upgrade the rail network across the Wellington region and cater for projected population growth over the next 25 years.

During the works, some train services may be affected. Visit Metlink to find out about bus replacements.


Substations - in progress

Substations take power from the local supply and convert it to the voltage needed by the trains. The trains then draw the power from the overhead wires. 

KiwiRail needs to upgrade some existing substations and build a new substation on the Kapiti Line to power the increased services that Metlink is planning from 2026.

Plimmerton Station BoL works Sept 2023

Kapiti Line upgrade - mostly complete

We are bringing the Kapiti Line up to a modern standard. This work includes upgraded station facilities, improved signalling, and the installation of a modern overhead power system.

Plimmerton Station upgrade - complete

A new platform at Plimmerton Station will reduce congestion, provide greater timetable resilience and lead to a higher frequency of services in the future.

The works also involve building additional shelters, constructing a third track through Plimmerton Station, realigning some of the existing track, resurfacing the existing central platform, and improving the underpass.

  • We’ve upgraded Steyne Ave and Pascoe Ave level crossings to comply with international safety and signalling standards.
  • We’ve upgraded the underpass at the north end of the platform.
  • We closed the pedestrian crossing at the south end of the platform for safety reasons. A new pedestrian crossing linking Steyne Ave to the central platform opened in early 2023.
  • We demolished the southern end of the platform to make room for the track alignment.
