Turnham Green () is a London Underground station in Chiswick of the London Borough of Hounslow in west London. It is served by the District and Piccadilly lines in a manner of cross-platform interchange, although Piccadilly line trains normally stop at the station only at the beginning and end of the day, running through non-stop at other times. To the east, District line trains stop at Stamford Brook and Piccadilly line trains stop at Hammersmith. The actual Turnham Green park is much closer to Chiswick Park station.
District line
Turnham Green station was opened on 1 January 1869 by the London and South Western Railway (L&SWR) on a new branch line to built from the West London Joint Railway starting north of Addison Road station (now ). 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).
Between 1 June 1870 and 31 October 1870 the Great Western Railway (GWR) briefly ran services from to Richmond via the Hammersmith & City Railway (now the Hammersmith & City line) tracks to Grove Road then on the L&SWR tracks through Turnham Green.
On 1 June 1877, the District Railway (DR, now the District line) opened a short extension from its terminus at Hammersmith to connect to the L&SWR tracks east of station (which had opened in 1873). The DR then began running trains over the L&SWR tracks to Richmond. This would have had a deep-level station at Turnham Green. The stations each side would have been at Heathfield Terrace and Emlyn Road. The plan was delayed by the First World War and an alternative route was adopted in 1920, which was not progressed. Express non-stop tracks were provided for the Piccadilly line between the stopping lines of the District line. from 23 June 1963. During the rest of the day they run non-stop through the station as before. Local residents have been campaigning for more Piccadilly line trains to stop at Turnham Green with trains only stopping in the event of delays to the District line whereby large numbers of passengers are left waiting on the platform or occasionally while scheduled maintenance work is carried out.
However, 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. A consultation published in January 2014, concluded that the business case would currently have an overall negative impact on business across London from introducing increased stopping at Turnham Green, but did outline the future plans to do so when upgrades had taken place, with passengers benefiting from improvements to the District line and the Night Tube (on Friday and Saturday nights, beginning with the Jubilee, Victoria, Central, Northern and most of the Piccadilly line,
