A teenager from Manchester, who died when he was struck by a commuter train at Waterbeach, had been helping his dad with a national van delivery round when the incident happened after stopping for a toilet break, it has emerged.

An inquest has been opened into the death of 17-year-old Lucas Jemison-Hine, from Eccles, who died on March 1 after being struck.

His dad, delivery driver, Jim Jemison, 48, from Stockport, was with his son moments before the fatal collision and only realised what had happened when he saw ambulances rush by and was drawn to Waterbeach railway station.

He has told how his son wasn’t suicidal, he wasn’t on drugs and he had no problems at home, but they had got lost on the way to a shop in Cambridge where they were due to deliver a refrigeration unit.

Mr Jemison said he stopped the van so his son could get out for a walk to find a place to go to the toilet and was somehow killed.

Being from the Manchester area he was not used to rural level crossings, he has said.

The incident was referred to the coroner by the British Transport Police and an inquest into the death was opened at Lawrence Court, in Huntingdon, and adjourned to September 7.

A post-mortem examination carried out on Mr Hine revealed that he died of multiple traumatic injuries.

Home schooled Lucas, an aspiring computer games coder, lived with his mother in Eccles.

It took them two days until Friday (March 3) to identify the body.
