Railway station in Travelcard Zone 4 opened 1850.

A temporary station east of Wood Lane, some 400 metres northeast of the current site, opened as "Hounslow" on 22 August 1849 to allow a service to run until the bridges, embankment, and station buildings were completed. The name was changed to "Smallberry Green" after four months.[2]

The present station opened on 1 February 1850 as "Isleworth". It was renamed "Spring Grove & Isleworth" in 1855 and became "Isleworth" again in August 1911.
