Boy's calls to dad's phone just to hear his voice after fatal crash

A family in Perth is coming to terms with an uncertain future after the death of father and husband Jaspreet Singh.

Singh's wife, Amandeep Kaur, was notified the moment her truck driver husband was killed in a crash with a freight train via an emergency alert text message.

"They were on each other's emergency contacts list, [the message said] 'SOS, Jaspreet has crashed at this location'," their 12-year-old son Samarveer Singh told 9News.

The boy and his mother paid tribute to 41-year-old Jaspreet, who was described as a hard worker, gentle soul and a devoted father.

Samarveer said he has been calling his father's phone just to hear his recorded voicemail message.

"We all loved him," Samarveer said.

"He was heartwarming, he was really kind.

"I'm feeling alone without my dad, and I miss him. I haven't slept, like, really well."

The family moved from India to Australia in 2018 and Jaspreet had been applying for residency.

His wife is now seeking her own and a fundraiser has been launched to support the family.

Samarveer said he hoped he and his mother could stay in Australia.

"I have to fulfil [Dad's] dreams, and everything he said, I have to do," Samarveer said.

"I have to take care of my Mum."

Police are investigating the truck driver's death at the Cardup railway crossing on May 5.
