Not sure about other Newcastle services, but the X21/22 looked like a mess around 5PM tonight, one X21 was running 40+ minutes late, and it was at Wansbeck Hospital when it should have been leaving Ashington on it's way back to Newcastle. A couple of X22's were also over 20/30 minutes late. 

All of these were just things I saw on the live map,  but it surely can't be that much out. (One of the buses would have been one I saw running late on its way to Newcastle about 3.30, unless there was a catastrophic amount of breakdowns)
