They announced it. They haven't actually done anything about it yet. I think there was supposed to be a consultation.

"Advance" tickets are a different concept entirely to peak/off-peak/super off-peak OR online discounts. An advance ticket theoretically saves you money because it ties you to a specific train and is non-transferable. Why that cost you more than a more flexible ticket travelling at the same time, I've no idea.

I've long since stopped buying tickets at the station if I can possibly help it. Tickets for immediate travel are always much pricier than those you can buy in... advance.
