William Young had just completed submarine training and had been drafted to HMS ORPHEUS when he died on 21 June 1967.

According to a report in the Rutland & Stamford Mercury dated 23 June 1967, he died from head injuries received after jumping from an 85 mph Newcastle to London express train at Tallington level crossing and hitting a signal. He was being escorted back to Portsmouth by three ratings, having been absent without leave, but was allowed to lock himself in the lavatory from which he jumped.  

He was in Newcastle as he was supposed to have been getting married on the previous Saturday.
