In July 1850 the WS&SWR was absorbed into the London and South Western Railway (LSWR).

On 1 January 1883 the LSWR opened a curve enabling down trains from Twickenham to pass the site of what was to become Whitton station and access the Hounslow Loop.

In the late 1920s the Southern was planning to extend its third rail electric train system from London Waterloo to Windsor & Eton (Riverside).

As today Whitton is a classic Southern structure with steel canopies and pre-cast concrete platforms.

In the 1980s and 1990s the station became part of Network South East and that changed due to the privatisation of the railways.
