She got a train from Manchester to London. I'm surprised that the price of this ticket wasn't mentioned (when the £4.90 one in London was). Manchester to London can typically cost anywhere between £40 to £90.
When it works and it's reasonably priced and you get a seat in a good environment it's the best form of travel. It's a shame those conditions so rarely all hold at the same time.
Chap got on at Doncaster, apologised for not having a ticket and handed over his card - £250!!
