The following notice is from Kiwirail, outlining the current works on the Johnsonville line. The original notice can be downloaded from here.
Dear neighbour
Wellington’s rail network is being progressively upgraded by KiwiRail and Metlink. We’re working together to enable more service reliability and more people and freight to travel on trains in the future. While the Network is well maintained we are renewing some of the older elements along the Line over the coming months. What’s happening on the Johnsonville Line? From early February 2020 we’re undertaking day-time works during off-peak travel times that include: Renewing traction power overhead line system between Ngaio and Johnsonville
Happening in several phases we will first do ground investigations, then pile to build new steel mast foundations, then stand the mast before finally installing the new overhead lines. Replacing sleepers within all seven tunnels
Undertaking slope stability work around Ngaio Gorge
