ACTION is being stepped up at a railway danger spot named as one of Britain's worst.
Tracks at Deighton are a magnet for teenagers, say safety campaigners.
And they're risking their lives to trespass.
The stretch of line that runs through Huddersfield is among the 20 worst in the north of England - plagued with trespass and damage.
Last year, rail chiefs counted 14 cases of rail vandalism in Deighton.
This week Network Rail launched National Railway Crime Week.
The awareness drive is timed to coincide with National Child Safety Week.
Figures show nine out of ten crimes on the railways are committed by under-16s.
Sixty people died trespassing on the railways last year - including six children who were killed playing or taking short-cuts across tracks.
Railway crimes include stones or other missiles hurled at trains, arson on board the carriages and objects left on the tracks.
Graham Botham, acting route director of Network Rail, said: "We must make young people sit up and take notice of the dangers and foolishness of using the railway as a playground.
"The consequences for these youngsters can be harsh - from being frog-marched home by the police to face angry parents, to hefty fines and imprisonment.
He added: "The crimes we see on the railway are often just the same as those being experienced on the other side of the boundary fence, although the consequences can be so much more tragic."
A documentary made by friends of a Leicestershire teenager killed playing on the line is being sent to secondary schools to hammer home the message.
