Three very quick observations:
1) Bournmoor seems to be the only place falling outside its county/borough line, it’s County Durham but appears to be in the Tyne and Wear Zone - a mistake?
2) Seaton Sluice and Holywell, I can’t make out what zone they are, Northumberland or Tyne and Wear? Or both?
3) They still haven’t sorted the messy titles of “City of Sunderland” ticket and “Sunderland Central” ticket, despite the former now extending down to Blackhall, which is closer to Hartlepool than Sunderland! I’m not sure why they haven’t renamed it “Sunderland + East Durham” to safe confusion across the board. How many folk in Sunderland may end up with the more expensive ticket when they’re just going Doxford Park to The Bridges?
