A railway guard will be sentenced for causing the death of a teenager who fell under a train.

Christopher McGee, 45, gave the signal for the train driver to depart as Georgia Varley, 16, was leaning against a carriage.

The guard was convicted at Liverpool Crown Court on Wednesday of manslaughter by gross negligence.

His two week trial heard that Georgia, who was on a night out in Liverpool with friends, fell between the train and the platform at the city's James Street station on October 22 last year.

The sixth form college student, from Moreton, Wirral, was three times over the legal drink driving limit and had 0.083mg of the drug mephedrone, or Mcat, in her system at the time of her death, the court heard.

The jury was shown shocking CCTV footage of the teenager's death. She was seen mistakenly getting off the train just before 11.30pm, and then turning around and leaning against the side as she realised her friends were still on board.

She was then seen to stagger and fall down the gap as the train moved off, before stopping after travelling around 30ft.

The prosecution said McGee, of Edenhurst Avenue, Wallasey, Wirral, was negligent because he failed to ensure it was safe for the train to depart.

McGee, who denied manslaughter, told the jury he thought Georgia was moving away from the train when he gave the signal to depart. He also said he did not know how drunk she had been.

He will be sentenced by trial judge Mr Justice Holroyde at Liverpool Crown Court from 10am.
