From Chris at 2009-06-30 20:50:49 : What route will these be used on? Is it an existing one or is there a cheeky angel rivaling route to Newcastle or something planned?
From Stu at 2009-07-01 16:07:45 : These are to replace the existing double deckers based at Bishop Auckland - which will be cascaded to other depots - and will be used on services 1/1B, 18, 56, 86 and X24.
From Buzzer at 2009-07-01 18:36:52 : Hope you gonna keep a few older deckers for school contracts Stu.
