In addition to the primary - Richmond service, there were services that linked Broad Street with and on the Watford DC line. Most of these were routed via the line between and Camden Road, calling at although some travelled via and joined the DC line at . Prior to electrification in the 1960s, other services ran as far as Tring on the West Coast Main Line via Primrose Hill and Willesden Junction Main Line (now demolished). 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. Trains were frequently cancelled owing to rolling stock shortages; these circumstances had begun some years earlier with service reductions and scrapping of trains in the late 1960s, followed in later years by closure of depots at Croxley Green and Stonebridge Park preventing stabling of spare stock. Along with what eventually became a lack of trains timetabled to serve Liverpool Street to match the needs of rush-hour passengers, this inevitably led to falling patronage. British Rail applied to close the service in 1990, and the last trains ran two years later.
