There used to be a Chester service to Witton Gilbert from Newcastle (21B), and I think that sort of got 'morphed' into the X25 with the Langley Park stretch. Not sure about South Shields, as far as I can remember, the 551 is now the 50, but it may have followed a different way from Chester to Durham.
