[8] The station building is a corner lot, located at the junction of two major roads, which are A24 Tooting High Street and A217 Garratt Lane.

[10] In the period following the end of First World War, the Underground Electric Railways Company of London (UERL) began reviving a series of prewar plans for line extensions and improvements that had been postponed during the hostilities.

The UERL wished to maximise its use of the government's time-limited financial backing,[12] and, in November 1922, presented bills to parliament to construct the W&SR in conjunction with an extension of the UERL's City and South London Railway (C&SLR) south from Clapham Common through Balham, Tooting and Merton.

[18][19] The Southern Railway objected to this encroachment into its area of operation and the anticipated loss of its passenger traffic to the C&SLR's more direct route to central London.

[17][note 2] Construction of the C&SLR extension was rapidly carried out and Tooting Broadway station opened on 13 September 1926.

[note 4] In 2013, it was announced that Transport for London's plans for Crossrail 2 included consideration of a station at Tooting Broadway.

In October 2015, the plan was changed in favour of a route via Balham due to difficult soil conditions at the proposed site.

[9] Tooting Broadway station features in the opening credits of the BBC comedy Citizen Smith and again in the closing sequence of the very last episode.
