Rail maintenance projects
Essential Track Maintenance
A lot of work is done to ensure every line on our network is maintained and services are able to run without delay. Where possible these are done at night but sometimes they require more time and can result in delays to trains or the replacement of services with buses.
Here are some examples of the regular work being done and why:
Track, tunnel and overhead wire inspections – regular track, tunnel and overhead wire inspections occur along each of the lines to ensure that proactive maintenance could be performed before it impacts the timeliness of services.
Clearing of vegetation – Throughout the network there are areas where trees can begin to overhang or drop leaves which can create delays on the line so doing this work is important to maintain the line.
Replacing rail – rail is exposed the elements on a day to day basis which means it must be replaced at regular intervals to ensure the safe and timely running of services.
Transmission Gully Road Upgrade – Kapiti Line
26 December – 2 January
The New Zealand Transport Agency (NZTA) has contractors installing a part of the motorway off-ramp over the rail at Kenepuru station as part of the Transmission Gully road upgrade project. If you would like to know more about the project visit the Transmission Gully projects page (external link) .
Yearly Line Maintenance – Hutt Valley/Wairarapa Line
26 December – 2 January
Preparation begins for upgrade work which is planned to take place on the Hutt Valley/Wairarapa line over the next 3-5 years. The bulk of the work will be occurring between Ava Bridge and Woburn stations where 1000 railway sleepers, specific track sections and large quantities of track foundation will be replaced.
Contractors will be doing concrete repair works at the Esplanade Bridge that doubles back over the railway lines. New traction structures ( the poles that hold the electricified wires above the track) will be placed along the motorway between Petone and Western Hutt Station and ongoing seismic strengthening works, platform and building and demolishing the station building at Ava Station as well as seismic and station building upgrade works will be completed at Heretaunga Station.
Other regular track maintenance will also be performed along the line.
Beautification of the network – Kapiti, Hutt Valley, Wairarapa and Johnsonville Lines
Work is continuously being done to make sure our network remains clean and tidy with the removal of rubbish on the lines. Working with community groups across our network work is often done to remove and cover up graffiti along the lines as well as planting along the rail corridor to prevent future graffiti.
