Calls for safety review of SA tourist train after man's death

There are calls for a new safety review of South Australia's iconic Cockle Train after an 87-year-old US tourist was struck and killed on the track.

The Victor Harbor Tourist Train was packed with holidaymakers when the crash occurred about 3pm yesterday, metres from Hayborough Beach at McCracken.

It is understood the 87-year-old man was walking along the track.

There were around 150 people on board when travellers heard a warning sound.

"It started to hoot and it went incessantly long," witness Tim Tolley said.

"I think it would have been hooting a warning sound for at least 10 seconds."

The train's driver has been treated for shock and organisers resumed train services this morning.

Locals and holidaymakers have raised concerns the warning signs around the train tracks aren't clear.

"There should be a lot more signage around this coastal track because I nearly did it myself," interstate tourist Peter Ebeyer said.

The train's operator has extended its condolences to the victim's family but said the line is safe.

"There's sufficient signage around the place, people have just got to abide by the signs," steam ranger Steven Richardson said.

The national rail safety regulator said initial investigations found no immediate safety concerns but enquires will continue in the coming weeks.

"I think the fact that the regulators and South Australia Police have approved the cockle train to recommence its services so quickly after the accident speaks to the fact that authorities believe the service is safe," Premier Peter Malinauskas said.
