By the time that Broad Street closed in 1986, the Watford services operated only in the rush hours; they were diverted to Liverpool Street by way of a new link in Hackney, known as the Graham Road Curve.
Da Broad Street lukkede i 1986 kørte Watford-togene kun i myldretiderne, og de blev omledt til Liverpool Street gennem en ny forbindelse i Hackney, kaldet Graham Road Curve.
