Still confused why the Explorer doesn't get you any futher on the Northern train than Blaydon or Sunderland since the ticket is valid all the way to Carlisle, Berwick & Scarborough (I think on the X93/X94) but it's probably been told before why it isn'tBecause the Northern line between Blaydon and Sunderland is the only bit that is included within the Network One ticketing system.
If the Explorer ticket was valid on more of the Northern Rail network, the Explorer ticket would be a lot more expensive. For example Northern sell a Tyne & Tees Day Ranger which is valid on LNER; Northern; TransPennine Express; CrossCountry services on the following lines: Morpeth - Darlington, Hexham - Middlesbrough, Bishop Auckland - Saltburn, Middlesbrough - Whitby & Middlesbrough - Northallerton. It is not valid before 09:00 and in 2019 it was £23.40 for Adult ticket - so more than double the £10.90 for the Explorer Ticket and it does not get you to Berwick, Carlisle or Scarborough (although the Explorer ticket is not valid on the Yorkshire Coastliner buses between York and Scarborough which is the only way you can get there by train):
