The construction of the Great Western Railway line from London to Bristol from 1838 reduced long-distance travel along the Bath Road. By 1842, the local paper was reporting that the 'formerly flourishing village' (which used to stable 2000 horses) was suffering a 'general depreciation of property'. The Hounslow Loop Line was constructed in 1850 - which prompted new development. Hounslow Hospital opened in 1876 and closed in 1978. Hanworth Road drill hall (now the Treaty Lodge Hotel) was built for the 2nd Volunteer Battalion, The Middlesex Regiment.
