Upgrades begin to allow more freight on Northland Line

Northland Line

Major works on New Zealand’s Northland Line have begun to enable more freight to be carried by train and faster passenger services.

The $204.5 million worth of works include replacing bridges, improving tunnels, and upgrading the rail line to Whangarei. Once complete, hi-cube containers will be able to be pulled on the Northland Line, enabling more freight to be carried by rail.

Services have been halted between Swanson, west of Auckland and Whangarei to allow for track occupancy and major civil works. Over the route, five bridges will be replaced and tracks will be lowered in 13 tunnels.

KiwiRail chief executive Greg Miller said that works are hoped to be completed by the end of the year.

“The work will be completed in stages, with the first objective being able to carry hi-cube containers through the tunnels between Whangarei and Auckland by Christmas.”

“Being able to carry hi-cube containers will also allow freight that can currently only come in and out of Northland by road, to instead go by rail. That additional transport option could help cut transport emissions and reduce the number of trucks on the roads,” said Miller.

Miller said that the delayed start was due to restrictions imposed by coronavirus (COVID-19).

“While our teams were able to continue design and planning work during the lockdown, COVID-19 halted most work on the ground. We’ve also been waiting on the arrival of specialist track laying equipment which has been held up by pandemic disruptions,” he said.

“This type of work can only be done while the line is shut. I regret the inconvenience for our freight customers and thank them for their patience. Once the line is upgraded, we will be able to offer more reliable train services to better meet their needs.”

Local businesses will be involved in the upgrade works, with Northland subcontractors tapped to provide supplies and carry out works.

“Local firm United Civil Construction has the contract to replace two of the bridges, all the ballast materials for the track upgrades are being supplied by Clements in Whangarei, and Busck, also in Whangarei, are supplying thousands of concrete sleepers,” said Miller.

In 2021, works on the Northland Line will continue, including the reopening of the line between Kauri and Otiria and the construction of a container exchange at Otiria.
