Hundreds of disgruntled train commuters in the capital have spent hours queuing for replacement buses after all trains were cancelled this afternoon.
It was caused by an overhead power fault - which left some stranded on trains on the hottest day of summer so far for Wellington.
Just before 3.30pm, Metlink notified commuters of the problem and recommended people find other transport options, and to check the Metlink website or app before travelling.
KiwiRail said there were two separate overhead power line failures that caused problems.
KiwiRail's metros general manager Jon Knight said power was restored to all Wellington railway lines affected by power outages, except between Petone and Kaiwharawhara, at around 6:05pm.
"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," Knight said.
Metlink said trains have resumed service from Wellington Station on the Johnsonville and Kapiti rail lines after being suspended by problems with overhead power lines. On the Hutt Valley Line, buses continue to replace trains.
"Metlink is grateful to our customers who have been waiting patiently for services to resume, and we ask them to remain patient while the backlog of passengers is cleared," a spokesperson said.
"We acknowledge the discomfort suffered by 139 passengers forced to wait onboard three trains that stopped between stations during today's power outage. Metlink greatly appreciates their patience and understanding while waiting to safely disembark.
"Because of today’s disruption, train services this evening may not run in accordance with Metlink timetables. Passengers are advised to check service alerts on the Metlink website or app before travelling."
