KiwiRail: Historical Maintenance

Stations Tracks Structures Tunnels

Description

In 2018 the Government made a large investment in overdue maintenance on Wellington’s rail infrastructure, such as replacing worn-out track and structures, redoing drainage systems and stabilising slopes. These works include:

  • Replacing all track on the Wairarapa Line (including inside tunnels and over bridges) in addition to drainage and vegetation work.
  • Stabilisation on the Kāpiti Line, as well as upgrading drainage in Tawa tunnels and renewing sleepers within the Paekākāriki tunnels.
  • Replacing track inside seven tunnels along the Johnsonville Line.
  • Renewing tracks and track connections at Wellington Railway Station.

Part of the historical maintenance includes renewing the track inside the 8.8km Remutaka Tunnel, which was built in the 1950s.

Updates

Benefits

A safer, more resilient network that can support future passenger growth. Renewing end-of-life infrastructure will enable KiwiRail to lift some temporary speed restrictions, improving journey times.
