runningman: What train station? The only railway next to Wakefield is that tiny one in the park! (although it's not that far from the main one, I always walk from there). A train journey must be part of it. It doesn't feel right going by any other means (including the argument with the conductor about why buying two separate tickets is cheaper than buying one - check Langwathby to Wakefield, vs. Langwathby - Appleby then Appleby - Wakefield).
Seriously, shows are held where they are because that's where the show's organisers are based. The RISC OS show locations have a pretty good geographical spread over England, so I doubt that moving them would make a great deal of difference. A Scottish one might.
