Arriva's allocations are purely to allow buses to leave Blyth on time, and are far more excessive than Go North East's planned allocations. As far as I know, the Hybrids have never appeared off route...

Yes, they are scheduled to do that but they were bought to operate between Durham and Newcastle.
