Mitcham Junction is a National Rail station served by Southern and Thameslink trains, and a Tramlink stop. It is in the London Borough of Merton and is in Travelcard Zone 4.
The station opened on 1 October 1868 specifically to provide an interchange between the new "South London & Sutton Junction Railway", later re-branded as part of the Portsmouth Line, and the existing "Wimbledon & Croydon Railway".
Despite its name, Mitcham Junction is no longer a railway junction; one of the lines that crossed here has become a grade-separated tramline, the Croydon Tramlink. Only the Portsmouth Line remains, used by services from Sutton and beyond to London Victoria, and from Sutton to London Blackfriars and beyond.
