A train driver was attacked as he passed through Feilding in the early hours this morning and had to lock himself in the cab for safety.
Shortly before 3am the KiwiRail locomotive engineer was driving the train alone in Feilding, when he noticed something amiss at the rear of the train.
After fixing the fault he was attacked by two people who had boarded the second locomotive illegally.
KiwiRail acting chief executive Todd Moyle said the driver was able to escape and lock himself in the cab.
The offenders threw rocks at the locomotive, smashing the front window.
