A better rail network for the Wellington region

Building your new rail network

KiwiRail, the Greater Wellington Regional Council and train operator Transdev are working together to continue to create a better rail network for Wellington commuters. The upgraded network will also benefit businesses that freight goods by train and reduce the number of heavy vehicles on the region’s roads.

We want to continue to make the network more reliable and cater to the growing numbers of commuters and freight customers using rail services. In the past decade KiwiRail’s upgraded track, tunnels, overhead wires and the traction masks which hold them, signals, sleepers and power supply to support the Council’s new trains and improve the Kāpiti line.

Now it’s the turn of the Hutt Valley and Wairarapa lines to see major improvements. This includes ‘double-tracking’ between Trentham and Upper Hutt – creating two lines so trains can travel in both directions at once.

In coming years, these improvements will mean fewer speed restrictions and outages which inconvenience rail customers. They’ll also enable MetLink to schedule longer trains, faster trains and more services for commuters, and KiwiRail to schedule more freight services for local businesses. The work to improve the network will take around seven years.

For safety reasons, much of this work needs to happen at night and during weekends and public holidays when there are no trains running and we can switch off the electrified overhead lines. We know that closing the line is inconvenient for commuters and that construction work can disrupt people living and working along the rail corridor. We’re working hard to get this essential work done as quickly as possible and thank commuters and our rail corridor neighbours for their patience.
