The Heworth to Washington section of the 529 was previously numbered 556, then the 526 before that.
Sorry - meant to say Lingey Lane to Galleries.
Aye, the 291/292 went via Stephenson, Sulgrave, Blue House Lane, but went via Blackfell, whereas this cut through Albany Village Centre.
Sure the 551 went up Blue House Lane and cut through Albany Centre at some point too.
