It looks like 36961 might have been a direct swap for 24109, and im sure I read somewhere on here that 22341/7 were at Walkergate for extra dupes over Christmas so presumably they can be withdrawn in the new year? Id like to hope these new E400s that are due will replace some single decker's too. Also does anyone know if any of Sunderland's deckers are euro 6 apart from 19641/2?
