[8][9] It was the first station of the extension of what was then known as the Hampstead & Highgate Line, which was built through undeveloped rural areas to Edgware.

Two passing loops were built at the station, not long after it opened, to allow fast trains to overtake slower ones here, but these extra tracks were removed in the 1930s.

The bridges over Highfield Avenue reflect this extra width, although both north and south of the station the alignment narrows again.

A planning application, registered in March 2008, for the nearby Brent Cross area[10][11] would improve bus services passing the station.

A turning circle for buses outside the tube station is proposed, needing the demolition of nearby housing.
