Power has been restored to almost all of Wellington’s train lines after a major fault stranded thousands of commuters across the region earlier today.

The Hutt Valley Line remains suspended between Wellington and Taita, with trains operating a shuttle service for the rest of the line to Upper Hutt, according to Metlink.

KiwiRail metros general manager Jon Knight said services were in the process of recovering.

“KiwiRail are aware of the significant disruption this has had on our customers and are using all resources available to restore full power so services can resume as soon as possible.”

He said electricity was restored across the system just after 6pm. Power is now available on all lines, except for a section between Petone and Kaiwharawhara.

Just before 3.30pm, Metlink notified commuters of the power issue and recommended people find other transport options.

At the time, Knight said several trains were stranded as a result of the power outage,

“As a result, three trains carrying a combined total of 139 passengers and six crew have had to disembark prematurely.

He said an issue was discovered with the overhead lines on the Johnsonville Line at around 1pm, and an overhead line in Kaiwharawhara came down at around 3pm.

“To complete safe inspections then complete restorative works, KiwiRail need to turn off the power at Wellington Station so that the issue can be addressed safely.”

Earlier this summer, KiwiRail imposed temporary speed restrictions on the train line between Wellington and Kāpiti as a result of track temperatures.
