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.

Wellington station overhead wire fix – All lines

25 -2 March 2018

You may have noticed the slow speed of services departing and arriving at Wellington station following the overhead disruption at the end of last month. A fault has been identified on the overhead wires which has led to ongoing speed restrictions in and out of Wellington station so work is needed to fix the issue and reduce these delays. To maintain the safety of track workers at one of the busiest sections of the rail network, no train services will be departing Wellington with bus replacements occurring on all lines.

For detailed information of the bus replacements and which stations they are between please visit our service updates page.

Level Crossing Upgrades – Wairarapa Line

10 – 11 March

Work will be underway between 10-11 March to upgrade level crossings at multiple points of the line between Featherston and Carterton. These upgrades will be occurring at Watersons line level crossing in Matarawa, Chester road level crossing in Clareville and Revan’s street level crossing in Featherston. The work is intended to help improve service reliability at these locations on 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.
