Auckland train services have been put on hold due to the fire in a scrap metal yard in South Auckland.
Fire and Emergency said crews were called out just after midnight to the blaze in a pile of scrap metal 10m high and covering 70 square metres at a yard on James Fletcher Drive.
Up to 30 trucks and support vehicles were at the scene in Favona throughout this morning.
Trains were halted until further notice after the KiwiRail control centre was evacuated because of the fire.
Auckland Transport said scheduled buses were running and would accept paper tickets.

An emergency message alert was issued to the neighbourhoods south of the fire at 6am residents to stay away from the smoke and keep doors and windows closed.
The alert covered Mangere, Otahuhu, East Tamaki, Papatoetoe, Manukau, Flat Bush, Manurewa and through to Takanini, Auckland Emergency Management said.
People were advised to contact their health provider if they were feeling affected by the smoke.

In Totara Heights, almost 15km from the blaze, resident Deven Jensen said the smell of burning plastic from the fire was detectable.
Jensen was woken by the emergency text alert and said he was concerned about the effect of the smoke on vulnerable people closer by, including Middlemore Hospital.
James Fletcher Drive is closed between Beach Road and Tui Street and several bus services were using a detour or had cancelled stops.
