Waka Kotahi's issued a prohibition notice effective immediately after drivers on the passenger train crashed red signal lights on two occasions.
In one case triggering a safety protocol which halted another passenger train that could have collided with Te Huia.
Investigations are underway after Kiwirail reported the safety breaches.

Waka Kotahi director of Land transport, Neil Cook, explains what happened.
Meanwhile Kiwirail says there will be replacement buses in and out of Auckland central to Papakura at no charge to Te Huia passengers this week, but after that, commuters will have to cover the cost.
