They're capable of it, but asking them to do it every day is never going to end well. Not forgetting one X14 board requires an X15 first as well.

As others have said it makes no real sense to send them to Northumbria. They'd need converted to Euro 6, and the oldest deckers in the fleet are currently at Durham so it makes far more sense to send them there imo.
