Urgent track upgrades lead to Auckland-wide speed restriction

Urgent upgrades to track around Auckland have led to KiwiRail imposing a 40km/h speed restriction across the entire network for the next six months.

Testing conducted on the network found that track wear was more widespread than previously understood, leading KiwiRail to bring forward repair work, said KiwiRail group chief executive Greg Miller.

“Following our testing we are accelerating our programme of replacing the most worn sections of rail and resurfacing less damaged sections.”

The speed restriction and need to access the track will disrupt commuter services, with services running every 20 minutes during the day instead of every 10 minutes during the morning and afternoon peak. Journey times will also increase, said Mark Lambert, executive general manager of integrated networks at Auckland Transport.

“We hope to add some extra services at peak times to ensure that we can meet passenger demand, but this speed restriction will unfortunately mean longer journey times for all our customers of up to 50 per cent for this temporary period.”

The works will involve replacing 100 kilometres of track and are expected to take six months. Miller said that KiwiRail had the local capacity to complete the upgrade.

“We are equipped and ready to resolve the issue with the necessary rail already in the country and staff available to lay it. Specialist rail grinding equipment, which will be used to remediate some of the rail, will arrive from Australia shortly.”

While the track upgrade work was anticipated, the move to level three restrictions in Auckland due to cases of COVID-19 has provided an opportunity for KiwiRail to begin sooner.

“We are working closely with Auckland Transport to arrange optimum access to the track so we can get to work as quickly as possible while managing operation of services,” said Miller.

“The faster this work can be completed, the sooner the network can be back to operating safely at full speed as we continue our work to deliver a resilient and reliable rail network for Auckland.”

The works form part of the NZ$1 billion upgrade package for Auckland’s rail network, which includes electrification from Papakura to Pukekohe.

“This is part of the critical upgrade of the rail track infrastructure in Auckland as we plan and prepare for significant increase in services when the City Rail Link is open, and dramatically reducing travel times across the region,” said Lambert. “We are working closely with KiwiRail to ensure the track infrastructure is ready for the future demands that will be placed on it that will continue the transformational journey of rail in Auckland with the opening of the City Rail Link.”
