Trespassing and vandalism on our railways costs the country £150million per year - cash that could be spent on improving train services for passengers.
Every year there are numerous cases of thieves stealing signal wire or electric cables, vandals putting obstructions in front of trains, hanging concrete blocks from bridges and throwing stones.

Every year people also lose their lives after being hit by trains while trespassing on the line.
So the recent spate of arson attacks on the line between Worksop and Retford is very serious indeed.
These idiots messing around on the tracks and lighting fires for their own twisted amusement are putting their own lives at risk - and potentially the lives of railway staff and passengers too.
Trespassing and vandalism delays services - as it did on the Worksop to Retford line this week - and can cost a fortune to repair.
It is important the authorities do all they can to keep people off the tracks, but they can only do so much.
It is more to do with educating people - the railway is not a safe place to be hanging around and causing trouble.
