KiwiRail has temporarily suspended a Northland route while still looking at the possibility of mothballing the Northland to Auckland line - four years after announcing a review of the line.
The government entity this week confirmed the discontinuation of the Dargaville line since a train derailed on the route in July due to a broken rail.
That route has also come under a cloud as KiwiRail has had only one customer using the line for the past 10 years.
Spokeswoman Jenni Austin said a full assessment which took into account the movement of relatively low volumes and the poor condition of the line that required significant investment over coming years had been undertaken since the derailment.
The locomotive had remained upright and wasn't damaged and the driver wasn't hurt. Ms Austin said the company lost most of the traffic on the line when the port was moved out to Marsden Pt.
