The family of a teenager killed when she touched a live rail are backing a campaign to highlight the dangers of trespassing on tracks.

Two years to the day since 17-year-old Jade Kenyon was killed, a DVD of her story was launched at the Malling School, East Malling, this morning.

Her mother Rachel Farrington, from Snodland, said although the family did not want to re-live the tragedy, they hoped it could help save lives.

She said: "It is too late for us. However, you don't want other people to go through what you've gone through."

Jade died on the Medway Valley railway line at Halling after taking a short cut home with a friend.

Miss Farrington believes better education in schools could have prevented the tragedy.

She said: "If she had known that live rail was on the outside as well perhaps she would never have walked down there."

Jade's twin sister Josie echoed her mother's sentiment.

"You don't really understand the danger this piece of metal on the floor holds. I think there is a lack in railway safety in schools."

The DVD, which has been almost two years in the making, is called Jade's Story and features interviews with Miss Farrington, 38, and Jade's father, Solly Kenyon, 40.

It has been made by Track-Off, a national railway safety campaign, with British Transport Police and Jade's family.

After today's launch it will be available for schools to order online.
