Transport officials are investigating the death of a person reportedly hit by a heritage train in Te Awamutu last night.

A Glenbrook Vintage Railway train reportedly “struck a person” at about 6.20pm at Te Awamutu station, according to the Transport Accident Investigation Commission.

Chief investigator Louise Cook said a team was now gathering evidence in the case.

“Our investigators will focus initially on establishing what happened and identifying any evidence that could assist the inquiry,” she said.

“Our first priority is to gather evidence while it is available. That includes examining the train and the scene, and speaking with people who witnessed the accident or were involved.”

Hundreds of people had been aboard the steam service, which was travelling from Glenbrook, east of Pukekohe, to National Park and back.

One passenger said she heard people yelling “stop” as the train left the station before it came to a halt, RNZ reported.

“It was seconds only,” she said.

 Senior Sergeant John McCarthy said emergency services were notified about 6.20pm on Sunday.

“We weren’t told what happened, but looking at the trauma of the bystanders… the trauma of staff, something I’ll never forget.”

Those in the rear carriages were moved forward before buses were reportedly arranged to take passengers to Hamilton and Glenbrook.

Senior Sergeant John McCarthy said earlier: “This is a tragic incident, and we are providing support to whānau and those who acted immediately to try to help.”

McCarthy urged anyone who witnessed what happened to contact police online, or by calling 105.

NZ Transport Agency Waka Kotahi, as the regulator for rail safety, was notified about the incident last night.

“Police is investigating, and NZTA is gathering information about the incident to determine if a separate investigation will be undertaken by NZTA as the rail safety regulator,” a spokesperson said.

“Heritage rail service operator Steam Incorporated Ltd has recommended (to their members and other operators) the suspension of heritage services in other parts of the country as a precautionary measure while investigations are undertaken.”

Police are also encouraging anyone who was present to seek support.

“This is a tragic incident, and we know that it will be distressing, Victim Support is available if needed,” Detective Sergeant Harry Hodgson.
