A stalled train between Newmarket and Britomart stations caused commuter delays in Auckland this morning.
The train has now moved but a backlog of passengers is still struggling to get to Britomart.
A passenger on the stalled train said it was stuck about 150m from the Newmarket station for about an hour.
Power went out just before 7am and the train started moving again just before 8am.
"The brakes slammed down and it's been rebooting over the past hour. The power comes on, then goes off again. The air con turns on, then it's out.
"People are annoyed, but there's nothing we can do about it.''
Auckland Transport is releasing up-to-date information for passengers travelling on other trains.
Trains can now come into Britomart but there's a 20-minute delay on the Southern Line and trains on the Eastern Line are delayed by up to 10 minutes.
Buses are also taking passengers to Britomart.
Auckland Transport said rail tickets and AT Hop cards would be accepted on all scheduled buses. However, passengers were being encouraged to find alternative transport.
Auckland Transport spokesman Mark Hannan said no extra buses were operating as a result of the train fault.
Passengers contacting the Herald this morning reported bus shuttle services were full and many people were still waiting to get on a bus in to downtown Auckland.
"I was affected coming in from the Western Line,'' Louise King said.
"Had a train person come along and tell us that we had stopped at Morningside station and could get off to wait for a Rail bus. Managed to get on another bus service but it was jammed packed - so many people not knowing what to do or where to go, looking very lost,'' she said.
Another passenger was on a train that got stuck at the Kingsland station.
She said about 50 people got off the train and had been waiting for a bus since before 8am.
"All buses going past are already full,'' she said.
