If you buy train tickets, and you collect them from one of those ticket machines in the train station, and you realise a few days later that the machine hasn't printed them all (or you've left the machine before they've all printed), what are the chances of them being reprinted by the train station staff?
As long as you're not doing it ten minutes before the train leaves you'll be fine. They'll probably just reprint your entire journey and allocate it new codes so the old ones don't work - unless the ones you're missing are just confirmations or reservations in which case they might just reprint those.
Anyone know why it’s cheaper to buy tickets Sheffield to Barnsley rather than Chapeltown to Barnsley? Even though the Sheffield stop is further away and goes through Chapeltown???
