The Te Huia train service returns to central Auckland this morning after temporarily being banned.

It's not been allowed on tracks in Auckland City after failing to stop for two red lights this year.

To celebrate its return, free tickets will be available.

Waikato Regional Council Deputy Chair Angela Strange says a system has now been installed which will stop the train if it passes a red light.

She told Mike Hosking that a more comprehensive solution will take a while.
