Hutt Valley Line

Much of our current work is on the Hutt Line. Our work will allow more frequent and reliable train services.

These works include:

  • Double tracking between Trentham and Upper Hutt – improving reliability and frequency of train services.
  • Replacing overhead power system – improving service reliability.
  • New power supply for signals – improving service reliability.
     

Double tracking Trentham to Upper Hutt

The rail line between Trentham and Upper Hutt will be double tracked to create two lines so trains can travel in both directions at once.

Double-tracking will support a more efficient Wairarapa service and help to minimise delays on this busy section of line. In time, it will allow for more frequent trains. Improvements will also be made to Trentham and Wallaceville stations.

KiwiRail, Greater Wellington, Metlink and TransDev held public information sessions in November 2019 - check out the information presented here.

Check out a virtual view of how the future double track will look.

RedwoodWEB

Trentham Station will get a new platform and new shelter on the racecourse side of the track. The new shelter, on the racecourse side, will be similar to Redwood Station (pictured).

We are also constructing a new pedestrian underpass at Trentham Station, once this is open it may replace the Camp Street pedestrian crossing.

 

 

 

 

AvaWEB

Wallaceville Station will get a new platform and two new station shelters which will be similar to those built at Ava (pictured). Access to the station will be improved to accommodate the new platform.

The pedestrian crossing at Ward Street will also be improved and fitted with automatic gates to make it safer for people crossing the railway line. The new signaling will ensure that  level crossing alarms will only be activated once departing southbound trains are ready to leave.

The pedestrian crossing just north of Wallaceville Station will be closed for safety reasons. This is because of the increased risk for pedestrians as the new double-track will mean more trains travelling in both directions. The Ward Street level crossing access to the station is less than 300m away. 

In the Upper Hutt Station area, we are renewing signals and carrying out track upgrades around the station area to adapt the layout to work with new double track. We're also upgrading and remodelling the level crossing at Blenheim Street to install automatic pedestrian gates

KiwiRail presented an overview the project to Upper Hutt City Council this year - here is the presentation.

Happening over 2.7 km of the rail network between Trentham and Upper Hutt this map shows key project activities.

Installing new overhead masts

Replacing overhead power systems can only be done when the electricity is off and no trains are running.

Overhead powerlines replacement

The overhead power system that powers Wellington’s trains was first built between 1938 and 1955. While the system has been well maintained, since 2007 we have been progressively replacing the system as it reaches the end of its useful life.

It is now the Hutt Lines’ turn to see the old wooden power poles and overhead wires replaced with a modern, traction system that will mean more reliable train services and provide a platform for increased services.  The new infrastructure will be installed in different places and look a little different.

Our construction teams are working their way along the line progressively installing the new equipment.

Building the mast foundations is a big job as we have to dig 5m beneath the surface to do this. Once they are complete,  the masts are fixed in and finally the wires themselves are installed.  Once the new infrastructure is in place, the old equipment will be removed.

This work can only be done while the power system is turned off and no trains are running, so is done mostly at night and weekends. 

 

 

Before works got underway we visited Trentham School so they could use virtual reality to view the plans and also understand the importance of staying clear of the tracks and looking both ways before crossing.

Where we are working now

November 2019 saw us entering the main construction phase. We are setting up our site  Trentham Station and getting ready to build the new underpass over the Christmas New Year Block of Line when no trains are running.

Before we could start the main build we needed to replace the overhead masts.

Travel while work is underway

Buses will replace trains when they can’t run on the tracks due to construction. Visit MetLink to find out about changes to passenger services in your area.

Works are underway to build a second 2.7km track between Trentham and Upper Hutt and they will take around 18 months to complete.

Most of the work can be done during the day with minimal impact on train services. However for some of it we will need to close the line. This will be outside of peak travel times such as at weekends.
