Boys reckless joyride on back of train alarms police

Police are investigating dramatic footage of two teenagers hanging from the back of a speeding train in Wellington.

The two males were captured "train surfing" yesterday afternoon by a car passenger as the train sped alongside the Eastern Hutt Rd, in Upper Hutt.

The boys, both believed to be about 14 years old, were spotted clinging to rails.

Police Senior Sergeant Bud Butler said the pair were first seen from Manor Park station on the southbound train, so they are thought to have got on before the stop.

Emergency services were alerted about 4pm and went directly to Taita station but the pair had gone, Senior Sergeant Butler said.

"It's very concerning because it's a very dangerous activity," he said.

KiwiRail general manager of metro David Shepherd said: "People who do this ... run the risk of not only killing themselves but also traumatising the people who then have to deal with the consequences of their actions."
