A very obvious sticker hides a rather monumental error on this Bakerloo Line strip map. The rather ugly abbreviation “Junct” only just covers up the fact that this sign used to read “Willesden Green” – which is on the Jubilee Line, not the Bakerloo! Prior to 1979 and the opening of the Jubilee Line, Willesden Green was serviced by Bakerloo trains – but we can’t even blame an old sign here, as this one only dates from the introduction of the Overground brand in 2007 at the absolute earliest. Whoops!
