NETWORK Rail says a campaign to keep trespassers off the railway line running through Swindon and Wootton Bassett seems to be working.

In August, the Evening Advertiser found several weaknesses in security near Wootton Bassett, such as holes in fencing and incomplete barriers along the track.

Simon Brooks, Network Rail spokesman, said Swindon had not suffered any serious incidents of railway trespass or vandalism such as people being seen on lines or items being thrown at trains since August.

"There are always little bits and pieces but nothing serious," he said.

"We are always looking to make sure the railway is as safe as possible."

Constantly flowing through the lines are 750 volts of electricity, presenting a serious risk to life.

Trespassing on or near a railway line is a criminal offence, and the British Transport Police has warned that those who survive a walk on to the tracks will be prosecuted.

Railway crime is estimated to cost the rail industry £150 million each year.

Margaret Barker, Network Rail's Route Crime Risk Manager, said: "If you are one of the adults who trespass on the railway not only are you putting your own life at risk, but you are also setting an appalling example to children who are with you or see you."
