Yesterday I seen one 56 going towards Gateshead Interchange from Sunderland NIS, and seen another coming from Gateshead Interchange towards Sunderland NIS. Both around 18.00.

Today I seen two 56 going towards Gateshead Interchange from Sunderland within 5 mins of each other, at around 17.00. Both NIS.

All four buses looked like they had a handful of passengers on, so I can only assume they were being "regulated".

Does all use of 'Not in Service' get reported on?
