Some trains in and out of Wellington this morning will be running at reduced capacity after more than a dozen were taken out of service yesterday.
Fifteen trains had to be checked for damage after an overhead power fault yesterday morning.
The fault - which has now been repaired - caused widespread delays for commuters.
Trains were out of action for most of the day after a new mast was incorrectly installed by contractors on Wednesday night in Hutt Valley as part of the $300 million project to upgrade Wellington's network.
