Kensington (Olympia) station is a station in West London managed and served by London Overground and also served by Southern and London Underground. It is in Travelcard Zone 2. On the Underground it is the terminus of a short District line branch, built as part of the Middle Circle, from Earl's Court; on the main-line railway it is on the West London Line from Clapham Junction to Willesden Junction by which many trains bypass Central London.
A station was opened by the West London Railway as its southern terminus on 27 May 1844 as "Kensington", located just south of Hammersmith Road; it closed at the end of November 1844 due to the losses made. Although a scant and erratic goods service ran, the line re-opened to passengers with a new station called "Addison Road" on 2 June 1862, located to the north of Hammersmith Road. Metropolitan Railway trains started serving the station in 1864, via a link to Latimer Road, with District Railway trains arriving in 1872. This enabled the so-called "Middle Circle" service to operate via Paddington to the north and South Kensington to the south. From 1869, the L&SWR operated trains from Richmond to London Waterloo via Addison Road, until their branch via Shepherd's Bush closed in 1916. In 1940 Addison Road, as well as the link to the Metropolitan line at Latimer Road, closed along with the other West London Line stations, but in 1946 it was renamed "Kensington (Olympia)" and became the northern terminus of a peak-hour shuttle service to Clapham Junction, as well as a District line shuttle to Earl's Court. The current District Line bay platform opened in 1958, but the previous (1872) connection between the District and the main line south of the station wasn't finally lifted until 1992. Two years later, a full passenger service between Willesden Junction and Clapham Junction was reinstated after a gap of 54 years.http://kensingtonandchelseamansions.blogspot.com/
