Sorry if this is in the wrong forum.
Basically, i'm going to the Durham open day on Tuesday. I'm going from Birmingham. I know that Durham is on the Edinburgh line and it's only ten quid from Brum to Edinburgh when it's almost £40 from Brum to Durham. I've been told about doing this before-buying a ticket to Edinburgh and just getting off in Durham.
Only worry i'd have is that if there are ticket barriers I might not be able to get through-are there any?
