During occasional closures on the District line, the Piccadilly line provides additional services to serve destinations on the District line such as Ealing Broadway. This is done either by diverting some trains bound for Rayners Lane and Uxbridge, or as a shuttle from Acton Town. Also, Piccadilly line trains may also run on the District line tracks between Hammersmith and Acton Town to serve the District line stations with no platforms on the Piccadilly line, namely Ravenscourt Park, Stamford Brook, Turnham Green and Chiswick Park.
