How did she not get nicked for pulling the train alarm though - that stops the train doesn't it. And you get fined if there is not good reason. I don't think 'nasty footy fans are swearing' is good reason and the article states this happened before they shouted at the woman at the station and she did her standing on the tracks bit.
FWIW I think she's a bit of a numpty, had a train come the other way she could have been blown under it and it's a bloody bad example to her son and everyone else.
Also I'm assuming there were not just evil footy fans on the train. They are now stuck in the middle of nowhere, Wales, because of her actions as well!
