On Tuesday, 29 June 1999 at approximately 1400 hours, an empty diesel multiple unit which had been parked on the suburban platform road at Papakura ran away towards the down main line at the north end of the station into the path of Train 3149, which was approaching from the north to the suburban platform road. The locomotive engineer of Train 3149 was able to stop his train before any collision occurred. No injuries resulted and there was no damage sustained.
The safety deficiency identified was the lack of security when diesel multiple units were left unattended.
One recommendation was made to the operator.
