Slight OT :  it really doesn't help things that the council's bounded themselves together for tourists and brand as NewcastleGateshead.

Most folk otuside the region think they are the same place, most would say Baltic, Sage and Angel are in Newcastle as opposed to Gateshead.

I doubt many people are making point to point journeys in Gateshead, I'd rather have seen a slightly higher fare option that incorporates the Tyne crossing
