After Tower Hill, the Circle line diverges, the District line joining the Hammersmith & City line just before Aldgate East station. The line passes over the London Overground at Whitechapel station before continuing on the Whitechapel & Bow Railway to Bow Road, where the line surfaces, and Bromley-by-Bow, where the line runs alongside the London, Tilbury and Southend line from Fenchurch Street station. There is an interchange with this line at the next station, West Ham, as well as with the Jubilee line and the Docklands Light Railway. There is a bay platform at the next station, Plaistow, and the Hammersmith & City line terminates at Barking station. The District line follows the London, Tilbury and Southend Railway for another eight stations, before terminating at Upminster station.
