Auckland train schedules have returned to normal after a massive fire in an industrial building factory in Penrose overnight disrupted this morning's services.
Fire fighters battled the blaze much of the night before bringing it under control this morning.
The fire broke out about 8.30pm at a concrete sales facility on Great South Road.
Fire and Emergency said at its height, 13 fire engines were fighting the blaze.
One crew was still at the scene dampening hotspots this morning, so it did not flare up again.
The building, a Hume concrete sales centre, has collapsed in the middle with mangled metal sheets and frame sticking out from the remains.
It backed onto train tracks, prompting the closure of Penrose Station.

Auckland Transport said there was a risk the building will collapse so services running from the nearby Westfield, to Newmarket were suspended this morning.
But it said trains on the Southern and Onehunga lines were now up and running again, although some delays were possible.
Meanwhile, two people were treated for smoke inhalation in another fire at a stairwell Auckland's Skycity at midnight.
Fire and Emergency acting shift manager Carren Larking said two people were taken to hospital.
"On arrival our fire crews found a fire in a hall in one of the stairwells, they did evacuate two people for smoke inhalation and we had 11 fire appliance on scene at the height of the fire,"
"We don't know the cause as of yet."
Fire investigators are looking into what started both blazes.
