Gatwick Airport railway station is on the Brighton Main Line in West Sussex, England.

It serves Gatwick Airport, 26 miles 47 chains (42.8 km) down the line from London Bridge via Redhill.

Gatwick Airport was the busiest station in South East England region (which excludes London) from 2017 to 2018.

Train services are provided by Southern, Gatwick Express, Thameslink and Great Western Railway.

When viewed from the air (or in satellite imagery), the station's British Rail logo etched on the roof is visible.

[5] Between late 2010 and early 2014, new facilities were built at the station, among them platform 7; infrastructure was renewed and the concourse was refurbished.

The facilities included passing loops and sidings, which enabled race trains to be held without impeding regular traffic on the Brighton Main Line.

[11] In the early 1950s, the airport was expanded over land formerly occupied by the racecourse, and it was decided to rebuild the station.

The station was integrated into the airport terminal via an upper level concourse designed by British Rail Southern Region.

[11] Automated teller machines, payphones and e-mail access points are installed on the main concourse.

[14] On 13 October 2010, a £53 million redevelopment programme was announced to provide another platform capable of accommodating 12-car trains, refurbishment of the concourse, and track and signal upgrades.

[11] By 3 February 2014, completion was marked by a ceremony officiated by Minister of State for Transport Baroness Kramer, who formally opened the new platform.

[19] In April 2018, Network Rail submitted a planning application for modernising the station; doubling the size of the concourse, widening two platforms, and improving connections to the airport terminal.

[20][21] The expansion is an element of a five-year programme, costed at £1.11 billion, announced by Gatwick Airport in early 2018.
