Whilst I understand the 33 and 12 shadow each other and obviously the 2 operates between Silksworth and Sunderland City Centre - it gives passengers an alternative, despite the 2 not being in direct competition for places between those points.
Obviously ticketing options play a part too.
The Silksworth Saver being valid on both the 2 and 33 in addition to the Sunderland day/week ticket and the red zone (plus whatever other colour that can be added) ticket.
