History.
Osterley station was opened on 25 March 1934 adjacent to the Great West Road which had been opened in 1925. The station was designed by Stanley Heaps in the modern European style used elsewhere on the Piccadilly line by Charles Holden. The design uses brick, reinforced concrete and large areas of glass and features a brick tower topped with a concrete "obelisk". Osterley station was a replacement for an earlier station, "Osterley & Spring Grove", located about 300m to the east on Thornbury Road, which was closed when Osterley opened. The old station buildings and platforms remain.
The station was served from its opening by trains from the District and Piccadilly lines, although District line services were withdrawn on 9 October 1964.
Step-free access.
In 2009, because of financial constraints, Transport for London decided to stop work on a project to provide step-free access at Osterley on the grounds that it was a relatively quiet station and within one or two stops of an existing step-free station, Hounslow East where step-free access has been available since 2005. In 2017, TfL announced that Osterley station would receive funding for step-free access, with work commencing in 2018. It is due for completion in 2020.
