Turnham Green station was opened on 1 January 1869 by the London and South Western Railway (L&SWR) on a new branch line to Richmond built from the West London Joint Railway starting north of Addison Road station (now Kensington (Olympia)). The line ran through Shepherd's Bush and Hammersmith via a now unused curve and initially the next station towards central London was Grove Road station in Hammersmith (also now closed). In the early 1930s, the London Electric Railway, precursor of the London Underground and owner of the District and Piccadilly lines, began the reconstruction of the tracks between Hammersmith and Acton Town to enable the Piccadilly line to be extended from Hammersmith to Uxbridge and Hounslow West (then the terminus of what is now the Heathrow branch). Express non-stop tracks were provided for the Piccadilly line between the stopping lines of the District line. Services on the Piccadilly line began running through Turnham Green on 4 July 1932. To provide a better interchange with the Richmond branch of the District line, Piccadilly line trains began stopping at Turnham Green station in the early mornings (from the first train until 06:50 Monday to Saturday, 07:45 on Sunday) and late evenings (from 22:30 until the last train) only from 23 June 1963. During the rest of the day they run non-stop through the station as before.
In December 2013, it was announced that Turnham Green will be made a permanent stop on the Piccadilly line once the line has been upgraded, with work scheduled to commence in 2019 and introduction of the first new train in 2022. The station is in both Travelcard Zone 2 and Zone 3. The station is located on Turnham Green Terrace (B491) on the eastern edge of Chiswick Common, but the actual green is much closer to Chiswick Park station. It is about 200 m north of Chiswick High Road (A315) and as well as Central Chiswick, the station serves the Bedford Park area. There is a flower seller located outside Turnham Green station. There are four ticket barriers and a gate that control access to all platforms. In the mid 1960s, Turnham Green was one of the stations used for the testing of experimental automatic ticket barriers later adopted throughout the network. There is a bridge, waiting room, help points and payphones.
