Railway station in Travelcard Zone 5.

It was opened by the London and South Western Railway on 1 February 1850 on completion of the bridges and embankments at Isleworth. A temporary station had opened as "Hounslow" some 400 metres northeast of the present Isleworth station on 22 August 1849 to allow a service to run until the loop was connected.
