'Hounslow' means something like the mound of the hound.
Old records spell it Hundeslow, from Anglo-Saxon Hundes hlaw: the barrow of a man named or nicknamed Hound. The town grew up on the boundary between the parishes of Heston and Isleworth. The station opened in 1886 as Heston & Hounslow and was renamed Hounslow Central in 1925, when Hounslow West and Hounslow East also took their names.
