A 5-a-side tournament, organised by British Transport Police (BTP) and Network Rail, saw teams from 14 comprehensive schools battle it out with Dyffryn School overcoming local rivals Glan Afan in the final. Sandfields were another entrant.
The event was supported by the Football Association of Wales and Brecon Carreg.
It aimed to promote alternative activities for youngsters to discourage them from trespassing on the railway.
During the tournament – at Swansea’s PlayFootball venue – each team of Year 8 pupils received a safety presentation featuring young people and families who have been affected by trespass on the railway.
Inspector Mike Edwards, who is in charge of BTP’s Welsh Neighbourhood Policing Teams, said: “The Railway Safety Cup is in its fourth year and as a result of the tournament’s growing success, we expanded this year by staging a girls’ tournament in South Wales.”
Dyffryn’s Megan Thomas was named Player of the Tournament.
