Western Line train services in Auckland were suspended for a time this morning, after a train stopped in its tracks.

Auckland Transport says the stoppage was due to a "train crew matter".

Witnesses have told Newstalk ZB the train stopped and the driver just walked away.

Traffic is building up on Morningside Drive and New North Road as a result.

Western Line services were already disrupted due to the partial closure of Britomart, following Wednesday's train derailment.

Train services are now returning to normal.
