Meningie man Harvey Betts, 62, died on Sunday when his truck collided with a freight train at a level crossing just off the Dukes Highway at Culburra, near Coonalpyn.

His family said while many members of the Meningie community were upset at not being able to attend his funeral because of coronavirus restrictions, it had been comforted by an outpouring of support.

"We've just been inundated," son Daniel Betts said.

Mr Betts was a prominent member of the Meningie community in South Australia's lower lakes region, and owned and operated his own business for over forty years.

"He was a self-made businessman back before I was born," his son said.

"He loved to work, but he loved his family as well."

His family described him as a "larger than life" man who was always keen to help others, and "loved mentoring young people in the community".
