RE: Pricing
Explorer tickets are indeed valid on Blaydon-Sunderland Northern Rail services, as I found out yesterday. I boarded at Metro Centre and the guard was sure that they were Newcastle-Sunderland only, and tried to make me pay a full adult return fare to NUNTHORPE! I said that the Network One site says at the very bottom that they're valid. He went off to check after he checked all of the other passengers tickets, after a few minutes waiting, he came out of the cab and gave a thumbs up...
