Mystery surrounds man found by side of Queensland road who was electrocuted while trying to jump on train

A man found beside a central Queensland road with life-threatening burns to his head suffered an electric shock trying to jump on a train, possibly to escape someone.

Police are perplexed by the case of the 20-year-old who is heavily sedated in a Brisbane hospital with burns to 90 per cent of his head and face.

Rockhampton Detective Senior Sergeant Luke Peachey said the man was suffering severe burns when he waved down a motorist at Wycarbah at 4.20am on Monday.

The man told the motorist he was burned trying to jump on a train to escape some people, the detective said on Wednesday.

"We have spoken to Queensland Rail and their system shorted out at about 4.20am," Det Sn Sgt Peachey told reporters.

"He has received burns to about 90 per cent of his face and head region."

Detectives traced the man's movements back to a licensed premises at Allenstown two hours earlier, where he was talking with two men and a woman.

He was later seen getting into a car with the trio but what happened after that until he was found by the motorist remains a mystery.

Detectives released CCTV footage of the trio from the pub and hope to ask them if they know what happened.

They also hope to speak later this week to the injured man, who underwent surgery today.

He remains in hospital - in an induced coma - with his mother by his side.
