She is sensible. I have no concerns about her walking around York alone or with a friend.
We've caught the train loads (to York and elsewhere). But there have never been any real issues other than delays.
She has never caught a train by herself. Over summer we went to a much smaller station (that we go to regularly) and she would have got the wrong train back if I hadnt been there which concerns me.
York is about 1.5hr direct train. Trains back are maybe every 1.5hr and finish quite late.
She wants to go with a boy she has known a few weeks and we've never met. They boy has never been on a train.
I want to get the same train there (sat in a separate carriage), then they can go off and do their thing in York while I do mine and then we catch the same train back (again I'll sit separately to them).
She thinks I shouldnt go. I just want to make sure they get the right train back.
