Rail services in Wellington are returning to normal on Monday evening after delays caused by a signalling failure.
The fault, which affected the evening rush-hour, caused the cancellation of a number of services, with others running only every half hour.
KiwiRail spokesperson Kevin Ramshaw says the fault has been fixed and passengers are being cleared, though there are delays to some services.
The signalling problems started after a power failure about 2pm.
Despite normal services resuming, passengers on the Capital Connection between Wellington and Palmerston North faced huge delays after a train broke down in front of them, five minutes out of Wellington.
The Palmerston North train is now hauling the other train back into Wellington.
KiwiRail says the service, which had already been delayed by the signal breakdown, is not expected to reach Palmerston North until 10pm.
