It's a quick connection, though, and I don't think having a single bus on the route would save any time. I could only see it working as an extension of the X88. I don't think GNE would want to extend the X22, as that would take them a long way off their usual territory. Following the X9/10 into the centre of Gateshead would be somewhat pointless.
