£3.15 to Chester from the Galleries.
You're probably right about it being more than £3.
That'll be down to the structure of the zonal system, at a guess?
Houghton to Chester is a two zone single ticket, and falls under what is likely to be the minimum charge for that ticket.
Same story for the bus from Chester to The Galleries.
Houghton to Durham is still a two zone single ticket, but that is probably the maximum charge for that ticket.
With that in mind, I'd guess the single price for the "Tynedalexpress" would be £3.95 too. £5.50 is the maximum fare for a return in two zones, so I guess the maximum fare for a two zone single would apply likewise.
