West Ealing railway station is on the Great Western Main Line in Ealing, west London. It is 6 miles 46 chains (10.6 km) down the line from London Paddington and is situated between Ealing Broadway to the east and Hanwell to the west. Its three-letter station code is WEA.
All main line trains serving it are currently operated by Great Western Railway and TfL Rail. In December 2018 the TfL Rail service will be re-branded as the Elizabeth line and in December 2019 the Elizabeth line service will open to Reading and Heathrow Airport.
The station was opened in 1871 as Castle Hill and Ealing Dene on the Great Western Railway, which was constructed from London Paddington through Ealing to Maidenhead in 1836–1838. From 1 March 1883, the station—then named Castle Hill (Ealing Dean)—was served by District Railway services running between Mansion House and Windsor. This service was discontinued as uneconomic after 30 September 1885. The station was located next to the London Co-operative Society's main creamery, and so was equipped with a dedicated milk train platform.
Originally the station consisted of four platforms in a staggered layout: platform 1 (along with a siding) and the island comprising platforms 2 and 3 to the west of the Drayton Green Road bridge, and platform 4 on the east side. Platform 1 and its siding were demolished in the late 1960s; platform 4 was demolished and moved west of the bridge by early 1990, partially covering the site of the then long-closed milk depot; platform 2 was partially demolished and fenced off by early 1991 as trains on the main line no longer serviced the station. From around 1985 to 1990, access to the original platform 4 was opposite the station building, across Drayton Green Road bridge. The current station building was completed in early 1987, following the demolition of the previous century-old building a year earlier. A west-facing terminating platform, platform 5, was added in 2016 for trains on the Greenford branch.
