Translink has appealed for adults to teach youngsters the dangers of railway lines after one near-miss incident.
Wednesday night saw three reports of pedestrians trespassing on train tracks, leading to a close shave on the Londonderry line.
The firm’s Ian Campbell, head of rail operations, said: “During school holidays, incidents of pedestrian trespass on the rail network unfortunately often increase.
“The network can look like a handy short cut or a good place to play, but the risks are just not worth it.
“Since the beginning of July this year there have been 79 incidents of pedestrian trespass on the railway network, ranging from groups of youths loitering at railway halts and bridges and young children running across tracks, to older passengers using tracks as short cuts.”
He added: “The message is simple – don’t ever use the tracks as a short cut or a playground and never try to beat the barrier at level crossings.”
